Bitbucket just added different levels of access to its APIs, enabling add-on and integration developers to request read, write, or admin access to repos, issues, wikis, and snippets. For Bitbucket users this means that add-ons and integrations now only get the level of access they actually need.
More details can be found in Bitbucket documentation.
Our previous OAuth1 implementation provided only all-or-nothing access to resources. As a developer building integrations or add-ons, you had less control. Additionally, some operations that were not possible via OAuth 1, such as cloning, are now possible via OAuth2, enabling a new set of add-on and integration functionalities.
How do I use OAuth2?
OAuth2 is available within webhooks, REST APIs, and Atlassian Connect for Bitbucket. When you register your application (add-on or integration) with Bitbucket you become an "OAuth consumer". OAuth 1 consumers that have been previously instantiated have been grandfathered into all-access. However, all new consumers will now need to specify the scopes requested, with a much more granular set of scopes available now for both OAuth options.
How does it impact me if I am a Bitbucket user?
You have complete control and visibility over what levels of access are granted to resources and repositories when you plan to use a certain integration or add-on. You may choose to grant access via a page similar to the one shown below:
You can also revoke access easily via "OAuth" under "Access Management" on your Settings page as shown below:
Please upgrade to OAuth2
We encourage all developers of Bitbucket integrations and add-ons to upgrade the authentication mechanism they’re using to scopes and OAuth2 wherever possible.
