Common acceptance failures
Trace a refused or stalled receipt back to the rule most likely causing it.
Receipts are being refused or held back more than you expected, and you want to know why. Most acceptance problems come from one of four places: a missing field, the spend amount, which stores count, or which locations count.
Symptom
Genuine-looking receipts are refused right away, get stuck, or fail to unlock the reward you promised.
Likely causes
Still stuck?
Test one obviously valid receipt and one obviously invalid receipt end to end. If a valid receipt still fails after the checks above, send support the challenge name and the two receipts you tested.
