Hello! I develop an application that designed to accept payments with Squareup. We've set up all the back-end and front-end wires: requests that are responsible for creating customer and processing transactions respond with 200 status, but after transaction request is done - no transactions appears in the transactions list on the dashboard. We're using sandbox application id and token, and we've tried both test and real card number, but none of them gave the result. Have someone issued such problem?
