INVALID_CARD_DATA error when saving card on file from webhook (after successful payment)

Hi team,

I’m encountering an issue while trying to save a card on file via the Cards API after a successful payment.

Here’s the flow:
A customer makes a payment using a Square-hosted payment link (Checkout API).

• The payment is successful — confirmed via the payment.created webhook.
• In the webhook handler, I attempt to save the card on file using:
  • payment['id'] as the card token
  • customer_id from the same webhook payload

Here’s the code I use:
$card = new \Square\Models\Card();
$card->setCustomerId($customer_id);

$body = new \Square\Models\CreateCardRequest(
uniqid(), // idempotency key
$payment[‘id’], // payment ID used as token
$card
);
$response = $cardsApi->createCard($body);

The issue:

• This works fine for most users — card is saved on file successfully.
• But for one specific client , the same logic throws an INVALID_CARD_DATA error.
• The payment still goes through successfully for that user.
  Any insights or guidance would be appreciated — thanks in advance! Please try to repond as soon as possible.
