Remove the Postal Code Requirement

Remove the postal code requirement from the In-App Payments SDK card entry form.

• You have integrated the In-App Payments SDK into your iOS or Android application.
• Your application can get the location country code of the seller who is taking the payment. This must be done by your server backend using the Locations API, because the payment is taken on the buyer's mobile device.
• Your application is based in a country that doesn't require the postal code for processing payments.

Your mobile application needs to make a request to your server backend to get the correct location and location country. To be valid, the target location must have ACTIVE status and CREDIT_CARD_PROCESSING enabled and the location.country field cannot be US, CA, or GB.

Follow the steps in Locations API Overview to find the correct location.

In the CardEntry.startCardEntryActivity method, set the collectPostalCode parameter to false.

public class CheckoutActivity extends AppCompatActivity {

 @Override
 protected void onCreate(Bundle savedInstanceState) {
   super.onCreate(savedInstanceState);
   setContentView(R.layout.checkout_activity);

   //Find the add card button and set a click listener that starts the CardEntry activity
   findViewById(R.id.addCardButton).setOnClickListener(v -> {
     //Start the In-App Payments CardEntry activity
     CardEntry.startCardEntryActivity(CheckoutActivity.this, false);
   });
 }
}
