Updating custom form values in JSM via REST

[Iain McCarthy]

Hi all. I am looking for some working examples of custom form field updates via REST.

I can't use custom Jira fields to map, as my forms use data connections, so must go direct through the forms API.

The Atlassian Doc falls JUST short of being useful, here:

https://developer.atlassian.com/cloud/forms/rest/api-group-forms-on-issue/\#api-issue-issueidorkey-form-formid-put

This provides the endpoint and request structure but no examples of the field data itself, which is the operative bit. 

--data '{
"answers": {}
}'

This document appears to show the valid structure, but I can't get it to work. If I send this as a payload (the long string is the field's dcId, I've also tried the numeric field number),

{
"answers": {
"68f27692-5a3c-4943-b7d4-b11d80e3f44b": { "choices": ["3441468"] }
}
}

I get the following response: 

 "errors":[{"status":400,"code":"BAD_REQUEST","title":"There was an issue with your request","detail":"1 error found in JSON: (1) should be a JSON object"}]}

Any example of drop-down, text and numeric field updates that you have working on your instances would be super helpful, thank you!

Hi Iain - have you also posted this over in the Developers Community?

I have not! Was not aware that was a distinct thing, thank you - if this question seems more appropriate for that spot I will ask over there.

I think you will get better answers over there. But leave this one here in case @Darryl Lee wants to chime in.

Hi @Iain McCarthy - the page you shared (Integrating Custom Form Fields into Jira Ticket Creation API) says:

(Experimental) Provides answers to the form associated with a request type that is attached to the request on creation. 

(Emphasis mine.)

So I believe that  this is only for populating a form when you are creating a NEW issue. 

You said you're looking to update fields on a form. I take that to mean you're wanting to change values on forms that have already been submitted.

My reading of Forms API is that to update an existing form you would need to:

• Get the IDs of all forms attached to an ticket: Get form index 
• Get existing answers for your form (assuming it's just one), using the formId from the step above. I think when you save answers you have to save all of them. So you'll want to get all the values that you'll need to retain or update: Get form simplified answers 
• You might need to reopen the form: Reopen form 
• Save the answers: Save form answers
• Submit the form: Submit form 

I (finally) found some pages with some examples (using web requests in Automation) that might help:

• Access forms data with the Forms API in Jira Cloud 
• Submitting or reopening a Form using Automation and REST API 
• Automatically update Form fields answers and manipulate more than one form on an issue 

I don't have time right now to test this myself, but those last two articles from @Bruno Altenhofen have a good amount of data. Maybe he can weigh in and see if my suggestions are correct.
