Test card returning INVALID_CARD_DATA Jquery\Php

[jjonesdesign]

Hey everyone.

After spending several hours developing a backend that is connected to sqaureup payment API, I started to get errors out of nowhere. It was working, then just randomly stopped.

I have jquery on the front end submitting the card data and getting a token back.

I then send this token to my internal API to attach the card to a customer's profile (which i've confirmed exists). Again this was working, and randomly now it's not.

My internal API is now sending back "error":[{"category":"INVALID_REQUEST_ERROR","code":"INVALID_CARD_DATA","detail":"Invalid card data.","field":"source_id"}]

I have been using the test card in sandbox mode: 4111 1111 1111 1111 with expiration 11/22, ccv 111 postal code 11111

I have also tried the other test cards provided in the documentation and get the same results.

I have confirmed that my internal api is getting the proper token from the front end.

Any suggestions on how I can get this test card to start working again would be great.

Thanks.
