Order already being charged on a reader
HTTP status 409 Conflict, code TERMINAL_PAYMENT_IN_PROGRESS.
What it means#
Another terminal payment for this order is still in progress. One order is charged on one reader at a time, so a repeated tap cannot take two cards.
What to do#
Wait for that payment to succeed or fail, or cancel it, then charge again if it is still due.
