Which authentication method to use to create a JIRA issue using REST API in R?

[Rajkumar Balakrishnan]

When I use the authentication methods provided in the documentation, it fails. I am not able to access projects created through JIRA Work Management. Am I looking at the correct help document? Can someone direct me to recent documentation that as a working script?

The authentication method depends on if you are on cloud or not.  For cloud, you can access the REST API with Basic Auth as described here: https://developer.atlassian.com/cloud/jira/platform/basic-auth-for-rest-apis/

Thanks a lot, @marc -Collabello--Phase Locked-! I am able to authenticate my credentials now. However, I am not able to create issues using the script as shown below using R (libraries: httr and RJSONIO). Kindly let me know what am I missing?

{
  "fields": {
     "project": [ABC"],
     "summary": ["TESTING SUMMARY"],
     "description": ["TESTING DESCRIPTION"],
     "issuetype": ["Story"],
     "assignee": ["5XXXXXXXXXXXXXXXXXX2"]
    }
}

 x <- list(fields=list(project=c(key="ABC"),
              summary="TESTING SUMMARY",
              description="TESTING DESCRIPTION",
              issuetype=c(name="Story"),
              assignee=c(accountId="5XXXXXXXXXXXXXXXXXX2")
           )
)

POST("https://sitename.atlassian.net/rest/api/2/issue/",body=RJSONIO::toJSON(x),
            authenticate("abcedfegeisadfksdalfkjsdlfkf=", "basic"),
            add_headers("Content-Type"="application/json"), verbose() )

How do I create a TASK using POSTMAN REST client? I am not able to use Basic authentication as both user id and password are required. At present, we are using base64(user id:password). I am in desperate need of a solution. Can you please help?

I am able to fetch Project information using the JiraAgileR package. But, not able to create a Task.

My recommendation is to look into the documentation and source code of https://github.com/atlassian-api/atlassian-python-api . The code is quite readable, and you could translate the methods you need into R.
