How to perform jira transition with attachment?

[Arthi Arumugam]

Am using REST Api calls to perform jira transition. It works perfectly when I perform a transition with a comment/ setting a field. However I am unable to find any help for performing a transition where field attachment is mandatory.

Any help is appreciated!

Natively within JIRA, you actually can't make the attachment a mandatory element.   But you might be able to use a 3rd party plugin like the JIRA suite Utilities to then add a workflow validator in regards to making sure the issue has an attachment say before executing a specific transition.  

There is talk about this on another post, please see How do you make attachment required on issue creat...

While that post is about the create screen in JIRA, it could still be used on other transitions.

I will have a look. Thanks Andy.
