POST /mobile/authorization-code stops working
Stopped working
Calls to POST /mobile/authorization-code on Square API stopped working on December 31, 2025.
What to use instead of these calls
Move the app from the Reader SDK to the Mobile Payments SDK, which authorizes with an OAuth access token and a location ID instead of a mobile authorization code.
Replacing the Reader SDK with the Mobile Payments SDK is a rewrite of the app's payment flow.
Calls it hits
POST /mobile/authorization-code
