Connecting two JSM instances

[Nadezhda Hristova]

Dear Atlassian community,

We are expecting to team up with another company on a certain project, so we are planning to connect our Jira instances. As for now, I am looking for a way to do it via API and simple automation (no third-party add-ons). The idea is for them to generate tickets for us through RUN or other triggers, to link the two tickets and, after that, I will need a script for copying the comments from ours to their issue and vice versa.

Could you suggest any options for this case?

P.S. I will get to find out if the other JSM is Cloud or Server based.

Regards,
Nadezhda

Hey @Nadezhda Hristova

since you're looking for a solution without apps, I'd recommend Automation in order to keep your tickets in sync. It's a bit cumbersome to do so, but it's possible in general.

You'd need to setup some automation rules like this in both instances:

• Send the creation of an issue
  • When: Issue created
  • If: Issue matches JQL (if you only want to sync specific ones)
  • Then: Send web request to Automation rule of other instance
• Receive issue creation
  • When: Incoming webhook
  • Then: Create a new Issue
    • with the details received in the webhook
    • make sure to store the issue key of the other side in a custom field for later reference
• Send the update of an issue
  • When: Issue updated (& possibly more events)
  • If: Issue matches JQL (if you only want to sync specific ones)
  • Then: Send web request to Automation rule of other instance
• Receive Issue Updates
  • When: Incoming webhook
    • run a JQL to set the related issue into the context
  • Then: Edit issue fields
• Send the comments
  • When: Issue Commented
  • Then: Send web request to Automation rule of other instance
• Receive comments
  • When: Incoming webhook
    • run a JQL to set the related issue into the context
  • Then: add comment to issue

I'd recommend to try out yourself if this solution works for you - or if it is too cumbersome. If that's the case, you can still go for an issue sync app from the marketplace. There are a couple of them. I'm part of the team behind Backbone Issue Sync and also happy to elaborate on that solution if you wish.

Cheers,
Matthias.

Hello @Matthias Gaiser _K15t_ ,

Thank you very much for the rapid and elaborate response :) 

I think I got the idea. Is it possible If you could give me an example URL for the web request? 

And also I cannot really figure out how to link the issues. A bit more help will be very appreciated :) 

Cheers,
Nadezhda
