REST API Authentication On Atlassian using Meetup as OAuth Provider

Download

Using this app, you can authenticate the Application 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 a number of operations such as Create Page, Delete Page, Add Comment, Create Space, etc. However, it supports only two authentication methods for REST APIs:

Basic Authentication
Using OAuth 1.0

The REST API Authentication plugin allows you to use any third party OAuth 2.0 provider/ OpenID connect to authenticate REST APIs. Here we will go through a guide to configure Azure AD as Provider.
