In-App Payments SDK
Java (Android)


If the country code for the targeted location is in the US, CA, or GB, you must not remove the postal code requirement. Doing so will result in all credit card transactions being declined.

The postal code requirement can be removed for all other countries.

  • You have integrated the In-App Payments SDK into your iOS or Android application.

  • Your application can get the location country code of the merchant who is taking the payment. This must be done by your server backend using the Locations API, since payment will be taken on the customer's mobile device.

  • Your application is based in a country that does not require the postal code for processing payments.

Step 1: Get the location country of the merchant

Your mobile application will need 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, CREDIT_CARD_PROCESSING enabled, and the field MUST NOT BE any of the following: US, CA, or GB.

Follow the steps in the Search for Locations to find the appropriate location.
