Connect GitHub repositories to sync documentation files into your Supermemory knowledge base with OAuth authentication, webhook support, and automatic incremental syncing.
The GitHub connector requires a Scale Plan or Enterprise Plan.

Quick setup

1. Create GitHub Connector

OAuth Scopes: The GitHub connector requires these scopes:
  • repo - Access to private and public repositories
  • user:email - Access to user’s email address
  • admin:repo_hook - Manage webhooks for incremental sync

2. Handle OAuth callback

Send the user to authorization.url before authorization.expiresAt. After the user grants permissions, GitHub redirects to your redirectUrl. A pending OAuth connector is not visible in list or get until the user finishes authorization. Once it is visible, the user can select which repositories to sync.

3. Select Repositories

Unlike most connectors, GitHub requires repository selection before syncing begins. There are two ways to set it:
  • Hosted picker: read the connector with include: "picker" and send the user to picker.url. The link works once and expires at picker.expiresAt.
  • Direct selection: if you already know the repository ids, pass them in selection.repos with connectors.update. A new selection replaces the old one and starts a sync.
See Managing Connector Selection for the generic selection API that GitHub, Gmail and Google Drive share.
The legacy GET /v3/connections/{id}/resources repository listing has no v5 route. The hosted picker shows the user their repositories and saves the selection for you.

Supported document types

The GitHub connector syncs documentation and text files with the following extensions:
  • Markdown files: .md, .mdx, .markdown
  • Text files: .txt
  • reStructuredText: .rst
  • AsciiDoc: .adoc
  • Org-mode: .org
Files are indexed as github_markdown document type in Supermemory.
Only text-based documentation files are synced. Binary files, images, and code files (.js, .py, .go, etc.) are excluded by default to focus on searchable documentation content.

Incremental sync with webhooks

The GitHub connector automatically sets up webhooks for real-time incremental syncing. When files are pushed or deleted in configured repositories, Supermemory is notified immediately.
Batch Processing: Webhook events are processed in batches with a 10-minute delay to optimize performance and prevent excessive syncing during rapid commits. This means changes pushed to your repository will be reflected in Supermemory within approximately 10 minutes.

How it works

  1. Webhook Setup: When you set the selection, a webhook is automatically installed in each repository
  2. Push Events: When commits are pushed to the default branch, changed documentation files are synced
  3. Delete Events: When documentation files are deleted, they’re removed from your Supermemory knowledge base
  4. Incremental Updates: Only changed files are processed, keeping sync fast and efficient

Webhook security

Webhooks are secured using HMAC-SHA256 signature validation with constant-time comparison. Supermemory automatically validates that webhook events come from GitHub before processing them. Each repository gets a unique webhook secret for maximum security.

Connector Management

List All Connectors

Update Repository Selection

You can update which repositories are synced at any time. The new selection replaces the old one and starts a sync.
When you update the repository selection:
  • New repositories are added and synced immediately
  • Removed repositories have their webhooks deleted
  • Existing documents from removed repositories remain in Supermemory unless you delete them manually

Delete Connector

Deleting a GitHub connector will:
  • Stop all future syncs from configured repositories
  • Remove all webhooks from the repositories
  • Revoke the OAuth authorization
  • Permanently delete all synced documents from your Supermemory knowledge base (unless you pass deleteDocuments: false to keep them)

Manual sync

Trigger a manual synchronization for all selected repositories. The call returns 409 while a sync for that connector is already running.

Advanced configuration

Custom OAuth application

For white-label deployments or custom branding you can connect with your own GitHub OAuth app. Custom OAuth credentials are an organization setting and are not part of the v5 connector routes. See Custom OAuth Applications.
Setting up a GitHub OAuth App:
  1. Go to GitHub Settings → Developer settings → OAuth Apps
  2. Click “New OAuth App”
  3. Set Authorization callback URL to: https://api.supermemory.ai/v3/connections/auth/callback/github
  4. Copy the Client ID and generate a Client Secret
After configuration, all new GitHub connectors will use your custom OAuth app instead of Supermemory’s default app.
