Getting JIRA ApplicationID in JIRA

[Robin Peters]

Hello,

I am writing a groovy postfunction where I want to create a confluence page with JIRA filters.

For this, I have to get the JIRA ApplicationId of the Confluence - JIRA application link to set up the JIRA filters correctly.
In JIRA I have the possibility to get the ApplicationId of Confluence with the ApplicationLinkService, but how can I get the JIRA ApplicationId?

I read something about HostApplication, but don't know how I can initialize it in groovy.

Can someone help me?

Best,
Robin

Can someone help me here?

At the moment, I set the id hardcoded, which is not nice.
