REST API Authentication On Atlassian using Google Apps as OAuth Provider

Enhance API Security for Jira REST APIs with OAuth/API Token plugin will let you authenticate any application (Jira, Confluence, Bitbucket) APIs using any third-party OAuth/OIDC provider or API Tokens. The app supports Azure AD, Keycloak, Okta, AWS Cognito, Google, Github, Slack, Gitlab, Facebook, and any custom provider.

Atlassian provides REST APIs to perform several operations such as Create Page, Delete Page, Add Comment, Create Space, etc. However, it supports only two authentication methods for REST APIs:
  1. Basic Authentication
  2. Using OAuth 1.0
The Enhance API Security for Jira REST APIs with OAuth/API Token plugin allows you to use any third party OAuth 2.0 provider/ OpenID connect to authenticate REST APIs of any application (Jira, Confluence, Bitbucket). Here we will go through a guide to configure Azure AD as Provider.

You can refer the steps to configure REST API Authentication using API Token from the video or documentation given below

Step 2: Fetch Access token through POSTMAN:

  • Open the Postman Application (Here is the link to download Postman Application).
  • Go to the Authorization tab.
  • From the dropdown select type as OAuth 2.0 and click on Get access token.
  • Add the following information from the table below.
  • Postman starts the authentication flow and prompts you to use the access token.
  • Select Add token to the header.
Field Value
Grant type Authorization Code or Client Credentials
Callback URL Enter the application's base URL if you dont have a callback URL
Auth URL  https://accounts.google.com/o/oauth2/auth
Access token URL  https://www.googleapis.com/oauth2/v3/token
Client ID Enter the Google Client ID
Client secret Enter the Google Client secret
Scope email
Client Authentication Send as Basic Auth Header

Step 3: Fetch Username through Google Apps:

  • Choose the method type as "GET".
  • Enter the interoception Endpoint from the plugin to fetch the username in the Request URL. For Google APP's it is "https://www.googleapis.com/oauth2/v1/userinfo?alt=json&".
  • Go to the Authorization tab select the Bearer Token and enter the access token here.
  • Add the header "content-type: application/json" and click on Send.

Request: 
     curl 
     -X GET 
     -H "Authorization: Bearer <Access Token>" 
     -H "Content-type: application/json" 
     https://www.googleapis.com/oauth2/v1/userinfo?alt=json&
Copy the attribute value against the username, you will need to configure it in plugin. In this example, the value is "email".

Step 4: Configure the Rest API plugin:

1: Enable Rest API Authentication:
  • After installing the app, click on Configure to configure plugin.
  • Select the Authentication type and navigate to Oauth/OIDC tab, then click on Configure.
  • From the drop down select Google as OAuth Provider.
  • Enter the attribute value against which we received the username in the Postman response.
  • Save the settings.
  • Now navigate to the Global Settings tab.
  • Here you will have to Enable the Authentication through Enable REST API Authentication and click on Save.
  • To configure the username attribute, click on Get username/email Attribute button.
