If you're not seeing the message in the Connect Failures log (Preferences >> Connect >> Failures), then this means that either:
- The message was never sent in the first place (perhaps because "Allow Envelope Publish" in the Connect configuration wasn't enabled when the Envelope event occured, or because the Envelope event or Sender that occured did not match any of those selected in the Connect Configuration).
OR
- Connect sent a message that was not acknowledged by the listener app, but "Require Acknowledgement" was NOT selected in the Connect configuration when the Envelope event occured -- therefore no failure was logged within DocuSign.
OR
- The message was sent to your listener successfully ("Allow Envelope Publish" in the Connect configuration was enabled when the Envelope event occured, and the Envelope event or Sender matched those selected in the Connect Configuration).
As long as your Connect settings are configured with "Allow Envelope Publish" selected and "Require Acknowlegement" selected, the Connect >> Failures page should always list any messages that were sent but not successfully acknowledged by the listener. Also, keep in mind that Connect will only send messages for the events and Senders that are selected in the Connect configuration.
Finally, if you select "Enable Log" in the Connect configuration, DocuSign will log (up to the most recent 100) messages sent, regardless of whether or not the message was successfully acknowledged. This log (Preferences >> Connect >> Logs) can be helpful for troubleshooting as well, since examining contents of any individual message in the log will show you whether the message was successfully received/acknowledged.
