Issue with adding values to a multi-select field in Jira Cloud via API

Question

I have a custom field that has 30+ values that can be chosen in any combination.  So for example the field could have A or A,B or A,B,C....the combinations are rather endless.  I have been struggling to update this field via an API for several weeks now.  I have read the documentation and have used the following per the documentation:

"customfield_10112": [{"value": "value1" },{"value": "value2"}] or

"customfield_10112": [{"id": 10156}, {"id": 10163}]

Neither of which work.  Work was done in Postman.  I confirmed that I can update other fields on the Jira ticket, just not this custom field.  I have read through various posts and tried a lot of different suggestions but to no avail.

It appears you are using Edit Issue one: https://developer.atlassian.com/cloud/jira/platform/rest/v3/api-group-issues/#api-rest-api-3-issue-issueidorkey-put

Sorry, I am out of suggestions on this symptom.  The syntax you originally tried for a multi-select custom field seems correct for an update using "fields" to replace the values or "update" with "set" or "add" operations.

REST API function....may not totally understand exactly what that means, but this is my what I use to send my request.

https://mycompanydomain.atlassian.net/rest/api/2/issue/AGT-1986?expand=editmeta

Correct, I send the request with the custom field update and I get a successful response, just no update in Jira on that specific field.

The metadata yess, I see the whole list of different 'valid values' and it is what I expect.

Another side note.  I did do a GET on a record where I updated this field in JIRA, it returned this:

"customfield_10112": [

{

"self": "https://personifyhealth.atlassian.net/rest/api/2/customFieldOption/10156",

"value": "Accordant",

"id": "10156"

},

{

"self": "https://personifyhealth.atlassian.net/rest/api/2/customFieldOption/10163",

"value": "Centene",

"id": "10163"

}

]

I copied this exactly and pasted into my request to see if it would update.  Again, successful response but no update in JIRA for this specific field.
