Buffer API
REST API for programmatically scheduling and publishing social media posts across multiple channels, retrieving post performance analytics, and managing connected social profiles.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Social media scheduling API. OAuth2. Agent can publish to social accounts — restrict carefully. Compliance review for regulated industries before posting.
⚡ Reliability
Best When
Best when you need lightweight, straightforward social post scheduling via API with clean OAuth2 auth and predictable REST semantics — a simpler alternative to Hootsuite for pure scheduling use cases.
Avoid When
Avoid when you need deep analytics, social listening, or high-frequency API calls; the 1000 requests/hour rate limit and v1 deprecation means agents must target v2 endpoints with proper migration.
Use Cases
- • Schedule posts programmatically across Twitter, LinkedIn, Instagram, and Facebook from an agent pipeline
- • Retrieve post performance metrics (reach, clicks, engagement) for automated reporting
- • Manage and rotate content across multiple social channels without manual intervention
Not For
- • Real-time social media engagement or inbox management
- • Complex multi-step campaign tracking with cross-channel attribution
- • Users on free tier who need full API capabilities beyond basic scheduling
Interface
Authentication
OAuth2 flow for third-party app access; personal access tokens available for single-account automation. Token scopes control read vs. write access to profiles and analytics.
Pricing
Pricing is per channel per month. Free tier exists but API access is restricted. Full API capabilities require Essentials plan or above.
Agent Metadata
Known Gotchas
- ⚠ API v1 is deprecated — agents must target v2 endpoints or risk breakage without warning
- ⚠ Rate limit of 1000 requests/hour applies globally across the account, not per-endpoint
- ⚠ Each social channel has its own profile ID that must be fetched and stored before scheduling posts — no shorthand aliases
- ⚠ Free tier API access is restricted; agents hitting free-tier accounts will encounter 403 errors on protected endpoints
- ⚠ No webhook support — agents must poll for post status updates rather than receiving push notifications
