GitHub - OAuth2

This feature is only available on the Pro and Enterprise plans.

Buf's SSO integration supports the following SAML features:

  • Identity Provider (IdP)-initiated SSO
  • Service Provider (SP)-initiated SSO
  • Just-in-Time (JIT) user provisioning

The steps below must be carried out by a GitHub administrator for your organization. These instructions can be followed alongside the Creating a GitHub App guide.

Prerequisites

  • Setup (Pro | Enterprise) needs to be complete.
  • You need to know your private BSR instance's domain name (for example, example.buf.dev or buf.example.com) for the steps below.

Create an SSO GitHub App

Note

This GitHub App is only used for SSO and is separate from the Buf GitHub App used for CI/CD integration.

  1. Sign in to your GitHub organization at https://github.com/organizations/YOUR_GITHUB_ORG/settings/apps.
  2. Click the New GitHub App button.

Configure GitHub App

Only configure what's listed here.

  • Set the GitHub App name to something like "Buf Schema Registry" or "Buf". This should be something meaningful to your users.

  • Set the Homepage URL to https://buf.example.com—this varies depending on your installation.

  • Ensure that Expire user authorization tokens is selected.

  • Under Identifying and authorizing users, set the Callback URL to https://buf.example.com/oauth2/callback

    • Sign-in redirect URIs should be https://buf.example.com/oauth2/callback
    • Sign-out redirect URIs should be https://buf.example.com/logout

  • Under Webhook make sure that Active isn't selected.

  • Under User permissions ensure that Email addresses is set to Read-only, no other permissions are needed.

  • Click Create GitHub App to create the app.

  • Click Generate a new Client Secret.
