I have attempted many different test credit cards as advised by the “getting started” guide. No matter what, I keep receiving this “card details are invalid” error. I understand that without this test card, I will be unable to test the APIs. Can someone help?

I realize that this topic was mentioned in 2018, but I am not sure who to reach out to now in 2025. Also, I have tried to follow the instructions there as well… but I am still stuck.

Hi @Champton, thanks for flagging this!

I’ve gone ahead and updated your Sandbox account settings — you should now be able to access and use the Sandbox environment without needing to enter a test credit card. Give it a try and let us know if you run into any other issues.

Cheers!

Hi @Andres, I just wanted to say thank you for updating my Sandbox account settings. That did the trick and I was able to work with the APIs.

Cheers!
