Changing issue transition with script runner

Question

Hello,

I am currently writing a script in script runner using the REST API.

The feature that i am implementing requires me to change the status of an issue.

Currently, the code looks like this:

def result = put("rest/api/3/issue/<My Issue>/transitions") 
.header('Content-Type', 'application/json')
.body([
transition: [
id: '61'
]
])
.asString()

When running the script, i get:

Method Not Allowed

I know that ID 61 is for me a valid status.

Any idea on what could be the problem?

Thank you and have a nice day!

Using post instead of put worked and changed the status. However i did not understand why?

As far as i know, put updates and post adds new entries. Here i am only interested in updating the issue
