I’ve built a plugin using ACE and I added three custom fields (single_select). What I need now is a way to populate these fields with values from a third party REST api.
Also, the values of he second select depend on the first and the third on the second. Is this at all possible and if so, how?
Hey @marknilsson
Have you checked out the REST API docs for updating custom field options? https://developer.atlassian.com/cloud/jira/platform/rest/v3/api-group-issue-custom-field-options/#api-group-issue-custom-field-options 
That sounds like what you’re trying to do. Get the data from the third-party REST API and then use it to set the options.
Thanks for the reply. The link you are referring to is deprecated but there is a substitution there I can use.
I was hoping I could set the options directly from the plugin but it seems that’s not possible. I’m now looking into the option of using a custom script to set the options I need.
By the way, the depency I described with 3 selects isn’t possible but with 2 it is when using a cascading select list.
