Fields with immutable values

[Jamie Gardyne]

I need to have a field with company name as the label/UI but a different immutable id as the value. The company name may change, but the id wont. I need to define the id as well as the value

Company name and id will be pushed into Jira using the Jira REST API from an external source. 

We have a team dedicated to getting this done, so integrations and infrastructure shouldn't be an issue.

What options do I have?

[Nic Brough -Adaptavist-]

Every field and field option has a unique immutable id.

I would create your "company" field as a simple select list (or multi-select).  You'll be able to rename the options the field without changing their immutable id.

Maybe I didn't explain well enough. I need to define the id as well as the value

You don't get to define IDs in Jira.

You'll need to find some app that can do id/data pair values, Jira does not have one natively.
