About "Payment API - Web" (Ref.: https://github.com/sumup/sumup-android-api#payment-api---web)

What does it happen if the callback URL you provide is down? Does SumUp retry to send the callback?

Hi there
At this point there is no retry implemented. If the URL is down, the response will be lost. To verify the status of a transaction, one can make use of the transaction identifier as part of the request. See https://github.com/sumup/sumup-android-api/#transaction-identifier
Partners can then verify with SumUp's transaction history API as a second source of truth:
