There isn't currently a jira<->tickets integration; if you were to build one yourself, you'd need to take advantage of the new Tickets API, which is currently in developer preview:
I think we have a number of different threads going now and it's somewhat confusing; if we're working in this thread, then I'll need more info on exactly what response you're getting. If we're working on the same issue in a different thread, feel free to ignore this one.
Hey @Joshua_McQueen , searching through the Integrations Page in my HubSpot account, I found a JIRA integration. Looks like it leverages the CRM Extensions API so you can peek into JIRA from the Contact, Company, or Deal record, or click on a link that brings you into JIRA. I can't see that it supports Tickets for Sevice Hub just yet since HubSpot just added support for CRM extensions on the Tickets Objects, but you can try downloading it and connecting from within the App Marketplace in your portal.
Totally feel you! I don't work for HubSpot or Atlassian, but maybe there's a way to bubble this up via a ticket with Atlassian since they're the ones that built the integration? Since support for CRM Extensions in Tickets only rolled out at the end of August it's likely that the integration just hasn't been updated yet -- I'd assume it'd be a relatively simple code change.
