Frequent errors:

The form will be rejected if:
  • The transmitted value is shorter than 6 digits.
  • The value is null.
  • The field is absent.
  • An identical transaction number has already been sent the same day.
    When the buyer clicks on "Cancel and return to shop", the transaction number will have to be different on the next attempt and the previous one will be considered as already used.

    If it is the same, the message "The transaction has been canceled" will appear.
