Easy Tech TutsHow to Find a Custom Field ID in Jira Easily 2026
By Impran M N
If you're working with Jira automation, scripts, or third-party integrations, you'll eventually need the exact ID behind a custom field. This guide covers a few reliable methods for finding that ID, from the admin settings to the REST API.
01Understand what a custom field ID is
Every custom field in Jira has an internal ID that automation, scripts, and integrations reference instead of the field's display name.
02Find the ID in Jira settings
Go to the custom fields administration page, where hovering over or clicking into a field's configuration often reveals its ID in the URL.
03Use the REST API to get the field ID
Query the Jira REST API's field endpoint, which returns a full list of fields along with their corresponding IDs.
04Use the field ID in automation
Reference the ID directly inside automation rules or scripts wherever you need to read or update that specific custom field.
