We are a consulting firm and provide access to our JIRA instance to multiple clients. we currently have 1 client in which we have integration with their zendesk. We now have another customer whowould like the same integration. When I contacted zendesk they indicated that they only are enable for 1 to 1 as the assumption in the zendesk and JIRA instances are with 1 company. I'm looking for options to meet my clients needs and allow has to integrate with more then one client's zendesk
