If you receive error code 403 when setting up Tap to Pay via SumUp in the iOS App SDK, this usually indicates a problem with access rights or certification. To fix this error, you should consider the following points:
- Check the Payment Scope: Make sure that the necessary payment permissions for Tap to Pay are enabled in your SumUp account. Without these permissions, access to the function may be denied.
- Check sub-account: If you are using a sub-account, it may have limited permissions. In this case, you should use the main account to ensure that all functions are available.
It is important to check your account settings and permissions regularly to avoid the 403 error and ensure smooth use of Tap to Pay.
