Hello, If you conducted the transaction within our sandbox environment, login to the sandbox account which was to receive the transaction and check the recent activity section, where you should see all the recent account activity including the transaction you completed. If you don't see the transaction under the recent activity, please share one of the following so I can review. 1. Merchant ID for the sandbox account which was to receive the transaction 2. Transaction ID for the completed transaction 3. The sandbox "client_id" which you used within the button code Please note, for sandbox transactions you should not be using a "real world" debit/credit card, but rather one of the test card numbers which can be generated from our card generator tool which is available on our developer site. Thanks !
