How can I know when a Jira has been asociated for a case?

Hi! I need to check in Apex whether a Case has an asociated Jira. Is it posible?

Hi @Alexis ,

You can add this into Outgoing Sync rule on Jira side:
replica.key = issue.key
And add this into Incoming Sync rule on ServiceNow side:
entity.correlation_id = replica.key
Other than the field ‘correlation_id’, you can use any other field or a custom field in ServiceNow.
How to Sync Any Entity in Exalate for ServiceNow
Note: It has to be added within firstSync block so that it could sync Jira WorkItem number with ‘Exalate’ operation.

I hope this helps.
Kind regards,
