Facebook Graph API Skill (Advanced)

Purpose

Provide a production-oriented guide for building Facebook Graph API workflows for Pages: publishing posts, managing comments, and operating Page content safely using direct HTTPS calls.

Best fit

• You need Page posting and comment workflows.
• You want a professional command design and safe operational guidance.
• You prefer direct HTTP requests rather than SDKs.

Not a fit

• You need advanced ads or marketing APIs.
• You must use complex browser-based OAuth flows.

Quick orientation

• Read references/graph-api-overview.md for base URLs, versions, and request patterns.
• Read references/page-posting.md for Page publishing workflows and fields.
• Read references/comments-moderation.md for comment actions and moderation flows.
• Read references/permissions-and-tokens.md for access types and scope guidance.
• Read references/webhooks.md for subscriptions and verification steps.
• Read references/http-request-templates.md for concrete HTTP request payloads.

Required inputs

• Facebook App ID and App Secret.
• Target Page ID(s).
• Token strategy: user token → Page access token.
• Required permissions and review status.

Expected output

• A clear Page workflow plan, permissions checklist, and operational guardrails.

Operational notes

• Use least-privilege permissions.
• Handle rate limits and retries.
• Log minimal identifiers only.

Security notes

• Never log tokens or app secrets.
• Validate webhook signatures.

Credentials & Secret Management

This skill requires the following environment variables to be set:

• FB_APP_ID – Your Facebook App ID.
• FB_APP_SECRET – Your Facebook App Secret (highly sensitive).
• FB_PAGE_ID – The target Facebook Page ID.
• FB_ACCESS_TOKEN – A Page access token with sufficient permissions.

Best practices:

• Store secrets in a secure vault or environment manager; do not hardcode.
• Use different tokens for development and production.
• Rotate tokens periodically and after any suspected compromise.
• Restrict App Secret access to minimal personnel.

Incident Response

If a token or secret is suspected to be leaked:

1. Immediately revoke the token in the Facebook Developer Dashboard.
2. Generate a new Page access token.
3. Rotate the App Secret if necessary.
4. Review logs for unauthorized usage.

Authentication

All Graph API calls must include a valid access token either as a query parameter access_token or in the Authorization: Bearer header. See references/http-request-templates.md for examples.
