We already have an existing Zendesk API Key which is used to authorize the Zendesk Web API calls in creating a ticket-based Slack application and worked previously, which is now giving the unauthorized exception when we connect to the zendesk api.
Any help would be much appreciated.
Thank you for posting your question to the Community. I went ahead and created a ticket for you as I'm going to need to get some account info in order to help troubleshoot this specifically.
Best,
Erica
