Jira REST API v6.4 - How to Authenticate Protected Calls

[LearnNShare]

Hello All. My organisation has Jira v 6.4 installed on an Internal Server. I am trying to understand how to use the REST APIs for protected operations. E.g. Login a User and Post a Comment on a Jira-ticket.

I found https://bitbucket.org/atlassian_tutorial/atlassian-oauth-examples/src?_ga=2.222679198.481098606.1529672290-1649287736.1529672290 which suggests how to use OAUTH 1.0a with Jira

Kindly confirm in case that is the only way to API calls in order to perform operations which require Authentication?

I am basically looking for a way to do this using Javascript alone.

Thanks

Hi, Amandeep, did you try using Basic authentication?

Hello Mikhail

Sorry, I didn't realised I should have referred /rest/auth/1/session in to https://docs.atlassian.com/software/jira/docs/api/REST/6.4/

I am able to get following response:

{
  "session": {
    "name": "JSESSIONID",
    "value": "D2796442969CE6E6355C6FA2DE3BBDE6"
  },
  "loginInfo": {
    "failedLoginCount": 13,
    "loginCount": 177,
    "lastFailedLoginTime": "2018-05-29T12:16:02.842-0400",
    "previousLoginTime": "2018-06-23T13:21:01.089-0400"
  }
}

Thanks
