Java API - Use Elements Connect API in Jira actions processing v6.0

Use case

Sometimes, you want to populate Elements Connect custom field during Jira actions processing. Jira has its own business model objects (like IssueInputParameters or CustomFieldParams) wich are forwarded throught actions chain. This is how you can use Elements Connect API to make it work.

Using the API

The following example shows how to set a value of a Standard Elements Connect field:
