Welcome to OneSpan Sign!

If you are using the default email service provided by OneSpan Sign, it also handles the email bounce.

When OneSpan Sign receives a bounce back, its response is to send a notification email to the sender mentioning their transaction was not received by the recipient (see attachment). In addition, it will also send out a callback notification if a listener has been set up and subscribed to the “bounced email” event, with a payload similar to below:


Note: There are two available values for the “message” parameter: "BOUNCE" and "OOTO". They tell your listener whether the event was triggered because the email is invalid or because of the OOTO reply.
