It seems like you're conflating exactly-once delivery with exactly-once processing. Your proposed solution is only necessary _because_ we can't have exactly-once delivery as TFA states.

This looks great! Will it be possible to create a link on a backend application and have all the frontend handled by Stripe?

Merry Christmas! I wish everyone a day of joy and love
