The error message you’re seeing, “INVALID_CARD_DATA”, typically indicates that there’s an issue with the card information you’re trying to process. This could be due to incorrect or incomplete card details such as the card number, expiration date, CVV, or postal code.

In your case, the error is pointing to the “source_id” field. The “source_id” should be a valid payment token or card ID. If you’re using a payment token, make sure it’s generated correctly using the Web Payments SDK or In-App Payments SDK. If you’re using a card ID, ensure it’s a valid card on file.

Remember, you should not directly use card information in the CreatePayment endpoint. Instead, you should use a payment token or a card on file.

If you’ve checked these details and the issue persists, it might be a good idea to review your payment processing flow to ensure it aligns with Square’s recommended practices.

We are saving the card on file to the developer account and errors are there. Can you please review our application what is wrong there?

What’s the application ID and is this for shared card on file? :slightly_smiling_face:

We have the same issue. Tried different credit card. Payments went through but when we tried to create new card for customers, the source_id error showed up. Even for new credit card.

For sandbox there is no issue. Only showed up when we moved to production.
