Magento 2: Get extension attributes data before customer address is saved

Question

We have created an extension attribute which we would be accepting via customer address REST API

Endpoint: PUT customers/:customerId

Request body:

{
 "customer": {
 "email": "[email protected]",
 "firstname": "test",
 "lastname": "test",
 "addresses": [
 {
 "region": {
 "region_code": "NY",
 "region": "New York",
 "region_id": 43
 },
 "country_id": "US",
 "street": [
 "Address1",
 "Verified"
 ],
 "firstname": "test",
 "lastname": "test",
 "default_shipping": false,
 "default_billing": true,
 "telephone": "8600360471",
 "postcode": "98761",
 "city": "New York",
 "extension_attributes": {
 "verification_status": 1
 }
 }
 ]
 }
}

Created an observer on customer_address_save_before however the following returns null: $customerAddress->getExtensionAttributes();

public function execute(Observer $observer)
{
 $customerAddress = $observer->getCustomerAddress();
 $verificationStatus = $customerAddress->getExtensionAttributes();
}

I need to fetch the extension attribute to save it to the customer address via REST API

There is also a custom attribute created but that too is coming as null when passed via REST API

Answer 1

Have you correctly declared the extension attributes via extension_attributes.xml? You will have to declare verification_status along with the expected type for Magento\Customer\Api\Data\CustomerInterface if you haven't already.
