callback

Hello,

We have an azure function setup to listen to onespan callbacks which works great nearly all the time, but on the rare occasion we get a failed callback. I supposed there is a number of reasons that could happen. In this specific case the error indicates a timeout exception.

I have a couple of questions

1 - When this exception occurs it appears that the onespan package sender/creator is notified via an email. here is a sample of the email

Hello,

I have a question with regards to callbacks. In our OneSpan account we have a callback URL configured to be used by one system for eSignature package events. We now are going to use the same OneSpan account for another system but want the events for package from the new system to be routed to a different callback URL.

We are trying to set up a URL to listen for Callback Notifications in salesforce. Following the API documentation here: https://community.onespan.com/documentation/onespan-sign/guides/feature-guides/developer/setting-callback-notifications I am a little confused as to how this would work in terms of Salesforce Authentication?

For the different callback notification events in https://community.onespan.com/documentation/onespan-sign/guides/feature-guides/developer/set-callback-notifications  what is in the sessionUser property in the payload?
