how to find system field id

[Rahul Savaikar]

Is there any way where I can find the IDs if the system fields and their values?

E.g. I want to have the ID of the Priority field and the Blocker field value.

you can find all JIRA fields IDs (system and custom) through rest call: {Your JIRA base URL} /rest/api/2/field

Thank you Moe, I will check this and send an update. Hopefully, this should work.

It doenot show any numeric value for system fields. ID will we displayed as characters.

Example: For System Field Name "Fix Version/s", "fixVersions" is the ID

[{"id":"fixVersions","name":"Fix Version/s","custom":false,"orderable"

Correct, system fields do not have a numeric id.

[Nic Brough -Adaptavist-]

Your script is not applying the change you've put into the mutableissue object.
