Jira REST API oauth2 and create issue via postman

[David Aslan]

I need to build a postman api call to jira using oauth2.0 but the docs and chat-gpt has gotten me confused.

In postman i go to the authorization tab and fill the following tabs:

• Type: OAuth2.0
• Token Name: AcessToken
• Grant Type: Authorization Code
• Callback URL: https://getpostman.com/oauth2/callback
• AuthUrl : provided by Authorization URL generator
• Access Token Url: https://auth.atlassian.com/oauth/token
• Client Id: provided by Authentication details in developer settings
• Client Authentication: Send as Basic Auth Header

In my body i have : 

{

    "fields": {

        "project": {

            "key": "DV"

        },

        "summary": "New task",

        "description": {

            "type": "doc",

            "version": 1,

            "content": [

                {

                    "type": "paragraph",

                    "content": [

                        {

                            "type": "text",

                            "text": "This is a new task"

                        }

                    ]

                }

            ]

        },

        "issuetype": {

            "name": "Task"

        }

    }

}

I do get to login but i keep running into 

"Hmm... We're having trouble logging you in.

We're having trouble logging you in. There seems to be an issue with your identity provider. Wait a few moments, then try again." 

But i also receive a cookie with the value: atlassian.xsrf.token=xxxxxxxxxxxxxxxMaybe secret numbersxxxxxxxxxxxxxx_lout 

Im not quite shure how to continue, the goal is to create an issue from postman and then replecate it via c#.
