[sandbox] inconsistent support of emails like [email protected]

Hi,

My OP was asking about possibly a broken sandbox credit card support on your end but I remembered that I had the same issue a while ago (see https://developer.squareup.com/forums/t/sandbox-card-4111-1111-1111-1111-does-not-work-anymore)

It would be good to unify the acceptance of test email addresses like [email protected] across your APIs (accept everywhere or reject everywhere).

Right now I can create a Square customer using this email address, but I’m unable to process any payment with it (eg when using Subscriptions).

All my best.

We’re constantly working to improve our features based on feedback like this, so I’ll be sure to share your request to the API product team. :slight_smile:
