While implementing and testing local currency payment flow for my app I got an error with the pay dialog.
error_code = 1383044 error_message = "no callback url" I have been reading the How-To at https://developers.facebook.com/docs/howtos/payments/ and the impression I got was that the payments callback was optional. However this error message seems to imply that it is required. Is setting up a payments callback a must for local currency payments?
(also, as a side question, are real time updates different from the payments callback? https://developers.facebook.com/docs...lfillment/#rtu)
