Method failed: (/rest/api/2/issue) with code: 400 when creating an Issue

I have been successfully querying projects and issues from JIRA. but i get an error when i try to create an Issue. Below is the data that i am trying to post to rest/api/2/issue endpoint


"{\"fields\":{\"description\":\"test\",\"issuetype\":{\"name\":\"Bug\"},\"project\":{\"key\":\"TSTB\"},\"summary\":\"this is a test\"}}"


Can anyone help identify what's wrong with the above syntax?

Your endpoint and data look fine to me. 

One quick check (although I'd expect a different error) - can you manually create the issue in the UI with the same data? 

Could you give us the line of code making the call, and the full error?

Hi Indira

Just to reassure you, I had been querying using the API for ages, then really struggled with my first issue creation.

Your JSON looks fine, so I don't think that that's the problem. Are there any required (mandatory) fields that you don't have in your JSON? This could result in an error.

Are you certain that you have an issue type of Bug?

Apart from the 400 code, what is the return message - it may give some indication as to what the problem is. 

What is the code and format that you're using in your Post?


Thank you Warren! Looks like the Priority field was mandatory. Once I set that, I was able to create the issue successfully.

Priority was a Mandatory field which had to be set in the JSON.
