Magento 2.2.6 : Shipment creation using REST API

Question

Unable to create shipment in Magento 2.2.6

I am using the following source code like this in postman

https://test.com/rest/V1/shipment

{ "entity" : { "order_id" : 70, "items" : [{ "order_item_id" : 94, "qty" : 1 } ], "tracks" : [{ "carrierCode" : "UPS", "order_id" : 70, "title" : "ground", "trackNumber" : "12345678", "parentId" : 1001 } ] } }

Thanks

• Anas Mansuri: this json reponse issue, try with without json format.
• shivashankar m: how can i revert it
• Rohan Hapani: @shivashankarm is it working for you?

Answer 1

It seems like your track array field format is wrong. Please try this below :

{ 
 "entity":{ 
 "order_id":70,
 "items":[ 
 { 
 "order_item_id":94,
 "qty":1
 }
 ],
 "tracks":[ 
 { 
 "carrier_code":"UPS",
 "order_id":70,
 "title":"ground",
 "track_number":"12345678",
 "parent_id":1001
 }
 ]
 ],
 }
}

UPDATE :

Go to this path /vendor/magento/framework/DB/Adapter/Pdo/Mysql.php and replace at line no 3036

case 'longtext':
 if (is_array($value)) {
 $value = json_encode($value);
 }
 $value = (string)$value;
 if ($column['NULLABLE'] && $value == '') {
 $value = null;
 }
 break;
