Hi Eric Alexandre,
To address the issue with your card being declined, please consider the following steps:
1. **Check Card Information**: Ensure that all card details are correct and the card is supported by Stripe.
2. **Enable Card**: After entering your card details, click the checkmark next to "LINK" to enable it.
3. **Set Default Payment**: Verify that your card is set as the default payment method in billing settings.
4. **Test Transaction**: Try a small transaction to see if it processes successfully.
5. **Screen Recording**: If issues persist, provide a screen recording of the error for further diagnosis.
For more information, you can refer to the [Stripe API documentation](
