How can I find the ID of a custom field in Jira 5?

[Drew Peifer]

I have found multiple articles on how to find the ID of a custom field using the API, but none without it. IMHO this should be a visible attribute when editing or configuring a Custom field.

The only solution I have found so far is to do the following:

• Enter administration section of Jira
• Go to Issues Tab >> Fields...
• View Field Configurations
• hover mouse over "Screens" link (in JIra 4 this worked for the "Edit" link, it is different in Jira 5 though)
• URL preview at bottom of browser will include fieldID=....

Has anyone found an easier solution? This becomes quite a pain if you have many custom fields and have to scroll down and hover over each screen link.

Actually, if you use the REST API Browser and execute the "field" command, or just run http://localhost/rest/api/2/field, you will get a list of all your configured fields, along with their ids.

To identify the custom field ID:

Icon

1. go to Administration/Custom Fields
2. click on the "Configure" link for the custom field you're interested in
3. in the URL of the Configure Custom Field page, note the number after "customFieldId=" and append it to "customfield_" to build the custom field ID

And if you have the customFieldId and you're looking for the Custom Field name? What do you have to do each and every custom field?

Surely there should be an easier way?

But How I can get the System field ID ?

/rest/api/2/field : Returns a list of all System fields as well as Custom fields.

Also you can find these kind of details here https://docs.atlassian.com/jira/latest/constant-values.html

It will still work on edit link, under Administration > Custom Fields - just hover over the Edit dropdown from the cog. Another way is to look into database but that will be even more painful!

You can access the system field with the equivalent name in english. According to this, the system field id for "description" is "description" .

To find a custom field ID / name I open JIRA exported data (.xml) file (backup file) with Notepad+ and search the value I know. Custom field ID and name are associated on same line.
