GetAllBidders
Use this call to retrieve bidding activity for a list of eBay users that have bid on an active or recently-ended auction listing.
Usage Details
GetAllBidders provides three modes for retrieving a list of bidders. The call is primarily used as part of the Second Chance Offer feature. In this case, the seller selects one bidder from the list of bidders returned by GetAllBidders. Then, using the bidder's UserID, they extend a Second Chance Offer for the item using AddSecondChanceItem. While this is the primary use-case scenario for GetAllBidders, the data returned in this call can be used for other purposes.
Working with the Response
GetAllBidders returns a list of the item's bidders with their associated bid information (bid time, bid amount, and so on). Traverse the elements in each Offer container to obtain details on each bid. As applicable to the application, store the pertinent data for later use.
If the listing has ended, determine which of the high bidders are actually eligible to purchase items from the listing (i.e., how many are actually winning bidders) and how many items each is eligible to purchase.
Note that if the seller designated the listing as a private auction, the user IDs of some bidders will not be returned. While the private listing is still active, the seller will only have access to the user IDs of the winning bidder(s). For any other bidders the user ID is returned as Invalid Request. If the function requester is other than the seller, all of the user IDs will be returned as Invalid Request (except for a bid by the requester). The seller will only have access to all bidders' user IDs through GetAllBidders (winning and non-winning bidders alike) after the listing has ended.
Testing GetAllBidders
You can test this call in the Sandbox environment. However, before testing GetAllBidders, you should have at least three test users. One is needed to list the item and two or more to bid on the listing. If the testing is part of Second Chance Offer functionality, use EndItem to end the item early after the bids have been placed.
It is a good idea to test GetAllBidders using all of the available inputs for limiting the list of bidders. For example, filter on second chance offer enabled and the bidder type. Test using these inputs individually and in combination.

| ErrorLanguage | string | Optional |
Use ErrorLanguage to return error strings for the call in a different language from the language commonly associated with the site that the requesting user is registered with. Below are some examples from different countries.
|
||||||||||||||||||||||||||||||||||||||||
| MessageID | string | Optional |
Most Trading API calls support a MessageID element in the request and a CorrelationID element in the response. If you pass in a MessageID in a request, the same value will be returned in the CorrelationID field in the response. Pairing these values can help you track and confirm that a response is returned for every request and to match specific responses to specific requests. If you do not pass a MessageID value in the request, CorrelationID is not returned. Note: GetCategories is designed to retrieve very large sets of metadata that change once a day or less often. To improve performance, these calls return cached responses when you request all available data (with no filters). When this occurs, the MessageID and CorrelationID fields aren't applicable. However, if you specify an input filter to reduce the amount of data returned, the calls retrieve the latest data (not cached). When this occurs, MessageID and CorrelationID are applicable. |
||||||||||||||||||||||||||||||||||||||||
| OutputSelector | string | Optional,
repeatable: [0..*] |
You can use the OutputSelector field to restrict the data returned by a call. This field can make the call response easier to manage, especially when a large payload is returned. If you use the OutputSelector field, the output data will only include the field(s) you specified in the request, as well as all of its child fields (if a field is a container) and its parent fields (if any). Note that it is possible that a field included through an OutputSelector field may still not be returned if it is not applicable, or if it is not found based on other criteria set up in the request payload. For example, if you are using GetItem and you only want to retrieve the URL of the View Item page (emitted in ViewItemURL field) and the item's Buy It Now price (emitted in BuyItNowPrice field), you would include two separate OutputSelector fields and set the value for each one as ViewItemURL and BuyItNowPrice as in the following example: If the following output selectors are used: See OutputSelector. |
||||||||||||||||||||||||||||||||||||||||
| Version | string | Conditional |
The version number of the API code that you are programming against (e.g., 1149). The version you specify for a call has these basic effects:
For the SOAP API: If you are using the SOAP API, this field is required. Specify the version of the WSDL your application is using. For the XML API: If you are using the XML API, this field has no effect. Instead, specify the version in the X-EBAY-API-COMPATIBILITY-LEVEL HTTP header. (If you specify Version in the body of an XML API request and it is different from the value in the HTTP header, eBay returns an informational warning that the value in the HTTP header was used instead.) See:
|
||||||||||||||||||||||||||||||||||||||||
| WarningLevel | WarningLevelCodeType | Optional |
Controls whether or not to return warnings when the application passes unrecognized or deprecated elements in a request. An unrecognized element is one that is not defined in any supported version of the schema. Schema element names are case-sensitive, so using WarningLevel can also help you remove any potential hidden bugs within your application due to incorrect case or spelling in field names before you put your application into the Production environment. WarningLevel only validates elements; it doesn't validate XML attributes. It also doesn't control warnings related to user-entered strings or numbers, or warnings for logical errors. We recommend that you only use this during development and debugging. Do not use this in requests performed in the Production environment. Applicable values: High if the user wishes to receive warnings when the application passes unrecognized or deprecated elements in an API call request. Setting the WarningLevel value to High is not recommended in a production environment. Instead, it should only be used during the development/debugging stage.Low if the user does not wish to receive warnings when the application passes unrecognized or deprecated elements in an API call request. This is the default value if WarningLevel is not specified in the call request.See Warning Level. |

| Return Value | Type | Occurrence | Meaning |
|---|
repeatable: [0..*] Each Offer container consists of detailed information on each bid made on an auction listing that is specified in the call request. Information in this container includes the amount of the bid, the time of the bid, and data for the user making the bid.
Applicable values: See Action.
Code so that your app gracefully handles any future changes to this list.
[ attribute currencyID ] CurrencyCodeType Always Dollar amount of the bid in the user's currency. This field is always returned but its amount will be the same as the value in the MaxBid field, unless currency conversion was actually performed.
For a list of possible enumeration values, see CurrencyCodeType.
Applicable values: See Currency.
Code so that your app gracefully handles any future changes to this list.
[ attribute currencyID ] CurrencyCodeType Always This amount indicates the highest bid that the corresponding bidder has made on the auction item. If that specific bidder has only made one bid on the auction listing, this value will be the same value as in the MaxBid field, but if the bidder has made multiple bids on the auction item, the HighestBid will show the highest of the bidder's bids, but MaxBid will show the value of the corresponding bid.
For a list of possible enumeration values, see CurrencyCodeType.
[ attribute currencyID ] CurrencyCodeType Always Amount of the offer placed. For auction listings, the amount bid on the item (subject to outbid by other buyers). For fixed-price listings, the fixed sale price at which the item is purchased. For auction listings with an active Buy It Now option, this amount will be either the Buy It Now price for purchase or the amount of a bid, depending on the offer type (as specified in Action). For PlaceOffer, the CurrencyID attribute is ignored if provided. Regarding Value-Added Tax (VAT): Even if VAT applies, you do not need to add VAT to the MaxBid value. If VAT applies to the listing, the seller can specify a VAT percent value when they list the item.
For a list of possible enumeration values, see CurrencyCodeType.
[ attribute currencyID ] CurrencyCodeType Always The maximum bid placed by the user making the call. This field is only returned if the corresponding bid was made by the user making the call.
For a list of possible enumeration values, see CurrencyCodeType.
.SecondChanceEnabled boolean Always Indicates the user's preference to accept second chance offers. If
true, the user is willing to be the recipient of second chance offers.
Applicable values: See SiteCurrency.
Code so that your app gracefully handles any future changes to this list.
.AboutMePage boolean Always
A value of
true indicates that the user has set up an About Me page. Note: This field will stop being returned in GetItemTransactions and GetSellerTransactions on January 31, 2024.
.BiddingSummary BiddingSummaryType Conditionally Contains information about the user as a bidder on a certain item. Returned by GetAllBidders if IncludeBiddingSummary =
true is included in the request.
.BiddingSummary
.BidActivityWithSeller int Conditionally This integer value is actually a percentage value that indicates what percentage of the user's total number of bids during the last 30 days (or the number of days specified in the SummaryDays field) has been placed on auction items that the seller has listed. The percentage value is rounded up to the highest whole percentage number.
This field is always returned with the BiddingSummary container.
.BiddingSummary.BidRetractions int Conditionally This integer value indicates the total number of bids that the user has retracted (from any and all sellers) during the last 30 days (or the number of days specified in the SummaryDays field).
This field is always returned with the BiddingSummary container.
.BiddingSummary
.BidsToUniqueCategories int Conditionally This integer value indicates the total number of bids made with unique listing categories that the user has placed during the last 30 days (or the number of days specified in the SummaryDays field).
This field is always returned with the BiddingSummary container.
.BiddingSummary
.BidsToUniqueSellers int Conditionally This integer value indicates the total number of bids to unique sellers that the user has placed during the last 30 days (or the number of days specified in the SummaryDays field).
This field is always returned with the BiddingSummary container.
.BiddingSummary.ItemBidDetails ItemBidDetailsType Conditionally,
repeatable: [0..*] This container provides information on each auction item that the user has placed a bid on during the last 30 days (or the number of days specified in the SummaryDays field).
.BiddingSummary.ItemBidDetails
.BidCount int Conditionally The total number of bids that the user has placed on the auction item.
.BiddingSummary.ItemBidDetails
.CategoryID string Conditionally Unique identifier of the eBay category that the auction item is listed under.
.BiddingSummary.ItemBidDetails
.ItemID ItemIDType (string) Conditionally The unique identifier of an item listed on the eBay site.
Since a bidder's user information is anonymous, this tag will contain the real ID value only for that bidder, and the seller of an item that the user is bidding on. For all other users, the real ID value will be replaced with the anonymous value, according to these rules:
When bidding on items listed on the US site: UserID is replaced with the value "a****b" where a and b are random characters from the UserID. For example, if the UserID = IBidALot, it might be displayed as, "I****A".
Note that in this format, the anonymous bidder ID stays the same for every auction.
(GetMyeBayBuying only) when bidding on items listed on the US site: UserID is replaced with the value "a****b" where a and b are random characters from the UserID.
When bidding on items listed on the UK and AU sites: UserID is replaced with the value "Bidder X" where X is a number indicating the order of that user's first bid. For example, if the user was the third bidder, UserID = Bidder 3.
Note that in this format, the anonymous bidder ID stays the same for a given auction, but is different for different auctions. For example, a bidder who is the third and then the seventh bidder in an auction will be listed for both bids as "Bidder 3". However, if that same bidder is the first bidder on a different auction, the bidder will be listed for that auction as "Bidder 1", not "Bidder 3".
(GetMyeBayBuying only) when bidding on items listed on the UK and AU sites: UserID is replaced with the string "High Bidder".
(GetBestOffers only) - all sites: The last part of the user ID is replaced with asterisks for users that submit best offers on an item. The seller of the item will be able to see the full User ID.
.BiddingSummary.ItemBidDetails
.LastBidTime dateTime Conditionally This timestamp indicates the date/time at which the user placed the last bid on the auction item.
.BiddingSummary.ItemBidDetails
.SellerID UserIDType (string) Conditionally The eBay ID of the seller who listed the item.
This will be returned with the anonymous value "Seller X", where X indicates where the seller falls in the sequence of sellers that the user has purchased items from. For example, if the seller is the third seller that the user has purchased items from, the value "Seller 3" is returned.
Note: Effective September 26, 2025, select developers will no longer receive username data for U.S. users through this field. Instead, an immutable user ID will be returned in its place. For more information, please refer to Data Handling Compliance.
.BiddingSummary.SummaryDays int Conditionally This integer value indicates the length of time (in number of days) that is being used to calculate all counts in the BiddingSummary container. This value is generally
30 (days), which means that all counts in the container have been calculated from the present time and going back 30 days in the past. This field is always returned with the BiddingSummary container.
.BiddingSummary.TotalBids int Conditionally This integer value indicates the total number of bids (from any and all eBay sellers) that the user has placed during the last 30 days (or the number of days specified in the SummaryDays field).
This field is always returned with the BiddingSummary container.
Since a bidder's user info is anonymous, this tag will be returned only to that bidder, and to the seller of an item that the user is bidding on.
.ShippingAddress AddressType Always This container shows the buyer's shipping address.
Note: For an Authenticity Guarantee program order returned in GetItemTransactions or GetSellerTransactions, this is the address of the authenticator's warehouse. The authenticator is responsible for delivery to the buyer's shipping address.
Note: For In-Store Pickup and Click and Collect orders, this is the address of the merchant's store where the buyer will pick up the order. This is only applicable for GetItemTransactions and GetSellerTransactions calls.
Note: For eBay Vault scenarios: GetItemTransactions calls, and GetSellerTransactions calls (Seller View only), mock address details are returned for:
- Vault to vault orders: Buyer and Seller View
- Ship to vault orders: Mock addresses are returned for the Buyer View (only); the address returned for the Seller View will be the authenticator's address.
- Vault in-hand submission orders: the address returned for the Buyer View will be the authenticator's address (GetItemTransactions only).
The following address details are returned for mock addresses:
<ShippingAddress>
<Name>eBay Vault</Name>
<AddressID>Invalid Request</AddressID>
<AddressOwner>eBay</AddressOwner>
<AddressUsage>Invalid</AddressUsage>
<CityName>Invalid Request</CityName>
<Country>US</Country>
<CountryName>Invalid Request</CountryName>
<ExternalAddressID>Invalid Request</ExternalAddressID>
<Phone>Invalid Request</Phone>
<PostalCode>Invalid Request</PostalCode>
<StateOrProvince>Invalid Request</StateOrProvince>
<Street1>Invalid Request</Street1>
<Street2></Street2>
</ShippingAddress>
.ShippingAddress.Country CountryCodeType Always The two-digit code representing the country of the user.
If not provided as input, eBay uses the country associated with the eBay Site ID when the call is made.
Applicable values: See Country.
Code so that your app gracefully handles any future changes to this list.
.ShippingAddress.PostalCode string Always User's postal code.
Max length: GB, DE - 35; US, CA - 40; AU - 80; Other countries - 50.
.eBayGoodStanding boolean Always
This boolean field is returned as
true if the eBay user is in good standing with eBay. Note: This field will stop being returned in GetItemTransactions and GetSellerTransactions on January 31, 2024.
An email address of another user is only returned if you and the other user are in an order relationship, within a certain time of order line item creation (although this limitation isn't applicable to the GetAllBidders call in the case of motor vehicles categories.) Based on Trust and Safety policies, the time is unspecified and can vary by site.
Since a bidder's user info is anonymous, this tag will be returned only to that bidder, and to the seller of an item that the user is bidding on.
For the GetOrders call, the buyer's email address will be returned (to the seller only) for orders less than two weeks old, but for orders that occurred more than two weeks in the past, the buyer's email address will no longer be returned. This Email field will still be returned, but 'dummy data', such as
Invalid Request will replace the actual email address. Note: For the GetItemTransactions call, this field is only returned to the seller of the order; this field is not returned for the buyer or third party.
Max length: 64 for US. May differ for other countries. Note: The eBay database allocates up to 128 characters for this field .
.FeedbackPrivate boolean Always Indicates whether the user has chosen to make their feedback score and feedback details private (hidden from other users). The percentage of positive feedback can still be returned, even if other feedback details are private.
Since a bidder's user info is anonymous, this tag will be returned only to that bidder, and to the seller of an item that the user is bidding on.
.FeedbackRatingStar FeedbackRatingStarCodeType Always
A visual indicator of an eBay user's Feedback score. A different colored star is used for each range of Feedback scores. See FeedbackRatingStarCodeType for specific values.
Note: This field will stop being returned in GetItemTransactions and GetSellerTransactions on January 31, 2024.
Applicable values: See FeedbackRatingStar.
Code so that your app gracefully handles any future changes to this list.
.FeedbackScore int Conditionally The aggregate feedback score for a user. A user's feedback score is the net positive feedback minus the net negative feedback left for the user. Feedback scores are a quantitative expression of the desirability of dealing with a user as a buyer or a seller in either side of an order.
Each order line item can result in one feedback entry for a given user (the buyer can leave feedback for the seller, and the seller can leave feedback for the buyer.). That one feedback can be positive, negative, or neutral. The aggregated feedback counts for a particular user represent that user's overall feedback score (referred to as a "feedback rating" on the eBay site).
If the user has chosen to make their feedback private and that user is not the user identified in the request's authentication token, FeedbackScore is not returned and FeedbackPrivate is returned with a value of
true. In GetMyeBayBuying and GetMyeBaySelling, feedback information (FeedbackScore and FeedbackRatingStar) is returned in BidList.ItemArray.Item.Seller. For GetMyeBayBuying, the feedback score of each seller with an item having received a bid from the buyer is returned. For GetMyeBaySelling, the feedback score of the seller is returned.
GetMyeBayBuying and GetMyeBaySelling also return feedback information (FeedbackScore and FeedbackRatingStar) in BidList.ItemArray.Item.SellingStatus.HighBidder. GetMyeBayBuying returns feedback information on the high bidder of each item the buyer is bidding on. GetMyeBaySelling returns feedback information on the high bidder of each item the seller is selling.
Since a bidder's user info is anonymous, the real feedback score will be returned only to that bidder, and to the seller of an item that the user is bidding on. For all other users, the value -99 is returned.
For GetOrders and GetItemTransactions only: If using Trading WSDL Version 1019 or above, this field will only be returned to the buyer or seller, and no longer returned at all to third parties. If using a Trading WSDL older than Version 1019, the accurate Feedback Score for the user is returned to the buyer or seller, but a dummy value of
0 will be returned to all third parties.
Indicates whether the user has been verified. For more information about the ID Verify program, see: Protecting your account
Note: This field will stop being returned in GetItemTransactions and GetSellerTransactions on January 31, 2024.
true if the eBay user has been registered on eBay for 30 days or less. Note: The Buyer.NewUser field will stop being returned in GetItemTransactions and GetSellerTransactions on January 31, 2024.
.PositiveFeedbackPercent float Conditionally Percent of total feedback that is positive. For example, if the member has 50 feedbacks, where 49 are positive and 1 is neutral or negative, the positive feedback percent could be 98.0. The value uses a max precision of 4 and a scale of 1. If the user has feedback, this value can be returned regardless of whether the member has chosen to make their feedback private. Not returned if the user has no feedback.
For GetOrders and GetItemTransactions only: If using Trading WSDL Version 1019 or above, this field will only be returned to the buyer or seller, and no longer returned at all to third parties. If using a Trading WSDL older than Version 1019, the accurate Positive Feedback Percentage value for the user is returned to the buyer or seller, but a dummy value of
0.0 will be returned to all third parties.
.RegistrationDate dateTime Always Indicates the date the specified user originally registered with eBay.
Since a bidder's user info is anonymous, this tag will be returned only to that bidder, and to the seller of an item that the user is bidding on.
Since a bidder's user info is anonymous, this tag will be returned only to that bidder, and to the seller of an item that the user is bidding on.
Applicable values: See Site.

.UserAnonymized boolean Always Indicates whether or not the User container has been made anonymous. If
true, some elements in the User container have either been removed, or had their values changed to remove identifying characteristics. If false, all expected elements are returned, and no values are changed. Since a bidder's user info is anonymous, this tag is returned as false only to the bidder, and to the seller of an item that the user is bidding on. For all other users, this tag is returned as
true.
Note: Effective September 26, 2025, select developers will no longer receive username data for U.S. users through this field. Instead, an immutable user ID will be returned in its place. For more information, please refer to Data Handling Compliance.
Since a bidder's user info is anonymous, this tag contains the actual value of an ID only for that bidder, and for the seller of an item that the user is bidding on. For other users, the actual value is replaced by an anonymous value, according to these rules:
When bidding on items, UserID is replaced with the value "a****b" where a and b are random characters from the UserID. For example, if the UserID =
IBidALot, it might be displayed as, "I****A". Important: In this format, the anonymous bidder ID can change for each auction. For GetMyeBayBuying only, when bidding on items: UserID is replaced with the value "a****b" where a and b are random characters from the UserID.
When bidding on items listed on the Philippines site: UserID is replaced with the value "Bidder X" where X is a number indicating the order of that user's first bid. For example, if the user was the third bidder, UserID =
Bidder 3. Note that in this Philippines site format, the anonymous bidder ID stays the same for a given auction, but is different for different auctions. For example, a bidder who is the third and then the seventh bidder in an auction will be listed for both bids as "Bidder 3". However, if that same bidder is the first bidder on a different auction, the bidder will be listed for that auction as "Bidder 1", not "Bidder 3". For GetMyeBayBuying only, when bidding on items listed on the UK and AU sites: UserID is replaced with the string "High Bidder".
For PlaceOffer, see also SellingStatus.HighBidder.
.UserIDChanged boolean Always If
true, identifies a user whose ID has changed within the last 30 days. Does not indicate a new user (see NewUser). Since a bidder's user info is anonymous, this tag will be returned only to that bidder, and to the seller of an item that the user is bidding on.
Note: For the GetItemTransactions call, this field is only returned to the seller of the order; this field is not returned for the buyer or third party.
.UserIDLastChanged dateTime Always
Date and time when the user last changed their eBay user ID (in GMT).
Note: The Buyer.UserIDLastChanged field will stop being returned in GetItemTransactions and GetSellerTransactions on January 31, 2024.
Applicable values:
Code so that your app gracefully handles any future changes to this list.
See Vat-exempt sellers.
Note: Effective September 26, 2025, select developers will no longer receive username data for U.S. users through this field. Instead, an immutable user ID will be returned in its place. For more information, please refer to Data Handling Compliance.
[ attribute currencyID ] CurrencyCodeType Always This is the dollar amount of the winning bid (if auction has ended) or dollar amount of the current highest bid (if auction is still active).

Code so that your app gracefully handles any future changes to this list.
Note: GetCategories is designed to retrieve very large sets of metadata that change once a day or less often. To improve performance, these calls return cached responses when you request all available data (with no filters). When this occurs, the MessageID and CorrelationID fields aren't applicable. However, if you specify an input filter to reduce the amount of data returned, the calls retrieve the latest data (not cached). When this occurs, MessageID and CorrelationID are applicable.

[ attribute ParamID ] string Conditionally This optional element carries a list of context-specific error variables that indicate details about the error condition. These are useful when multiple instances of ErrorType are returned.
Applicable values:
If the source of the problem is within the application (such as a missing required element), change the application before you retry the request.
- If the problem is due to end-user input data, please alert the end-user to the problem and provide the means for them to correct the data. Once the problem in the application or data is resolved, you can attempt to re-send the request to eBay.
- If the source of the problem is on eBay's side, An application can retry the request as-is a reasonable number of times (eBay recommends twice). If the error persists, contact Developer Technical Support. Once the problem has been resolved, the request may be resent in its original form.
See the Error handling section of the Making a Trading API call guide for more information.
When a warning occurs, the error is returned in addition to the business data. In this case, you do not need to retry the request (as the original request was successful). However, depending on the cause or nature of the warning, you might need to contact either the end user or eBay to effect a long term solution to the problem to prevent it from reoccurring in the future.

Note: GetCategories and other Trading API calls are designed to retrieve very large sets of metadata that change once a day or less often. To improve performance, these calls return cached responses when you request all available data (with no filters). When this occurs, this time value reflects the time the cached response was created. Thus, this value is not necessarily when the request was processed. However, if you specify an input filter to reduce the amount of data returned, the calls retrieve the latest data (not cached). When this occurs, this time value does reflect when the request was processed.
Detail Controls
DetailLevel
This call does not support varying Detail Levels. You do not need to pass DetailLevel in the request.
