Happy Monday ​@rod_sanz—welcome to the Community!

I’m not seeing any fields on the Update Ticket action that would allow a Jira issue to be linked. I’d suggest contacting our Support team to submit a feature request for that sort of functionality to be added. You can do that here: https://zapier.com/app/get-help.

In the meantime, perhaps you could try using an API Request action or Custom Action for Zendesk.  As it looks like you could use Zendesk’s Create Link endpoint to create the link between the ticket and the issue. It’s a bit more advanced as you’d need to reference Zendesk’s API to set up the request but if you go down the custom action route it has an AI powered Copilot feature that can help to set it all up for you. You can learn more about how to use API request and custom actions here: 

• Create an API Request action
• Create a custom action

Hope that helps to point you in the right direction. If that helps to solve things for you please mark it as the best answer. And if you run into any issues or have further questions just let us know!
