View OpenAPI Spec

Jentic publishes the only available OpenAPI specification for Buffer API, keeping it validated and agent-ready.

Schedule, publish, and manage social media posts across multiple profiles from a single API with 18 endpoints. Queue content updates with specific scheduling times, reorder and shuffle post queues, track sent post analytics, and retrieve per-profile scheduling configurations. Supports posting to Twitter, Facebook, LinkedIn, and other connected social accounts through a unified content management interface.

Use Cases

Patterns agents use Buffer API API for, with concrete tasks.

★ AI Agent Content Scheduling

An AI agent generates social media content and queues it for publishing across connected profiles by calling POST /updates/create with profile_ids, text content, and optional scheduled_at timestamps. Through Jentic, the agent discovers the scheduling operation by searching 'schedule social media post', loads the request schema with supported fields, and executes without manual API key management. Handles multi-profile posting in a single request.

Create a scheduled post via POST /updates/create with text 'Check out our latest blog post!' targeting profile_ids ['abc123', 'def456'] and scheduled_at set to tomorrow at 9:00 AM UTC

Queue Management and Optimization

Retrieve pending posts for a profile via GET /profiles/{id}/updates/pending, then reorder them by priority using POST /profiles/{id}/updates/reorder or move individual posts to the top with POST /updates/{id}/move_to_top. Shuffle the entire queue randomly using POST /profiles/{id}/updates/shuffle for content variety. Supports queue manipulation without recreating posts.

Retrieve all pending updates for profile-id 'abc123' via GET /profiles/abc123/updates/pending and move update-id 'upd789' to the top via POST /updates/upd789/move_to_top

Multi-Profile Publishing Analytics

Fetch sent post histories for each connected profile via GET /profiles/{id}/updates/sent with pagination to analyze publishing patterns and engagement. Retrieve profile-level schedule configurations showing posting time slots via GET /profiles/{id}/schedules. Compare performance across Twitter, Facebook, and LinkedIn profiles from a unified data source.

Retrieve the last 25 sent updates for profile-id 'abc123' via GET /profiles/abc123/updates/sent?count=25 and return the text and statistics for each

Link Share Intelligence

Look up how many times a specific URL has been shared across the Buffer network using GET /links/shares with the url parameter. Provides aggregate share count data for content performance assessment and viral potential analysis before scheduling reposts or follow-up content.

Check how many times 'https://example.com/blog-post' has been shared via GET /links/shares?url=https://example.com/blog-post and return the shares count

Why though Jentic?

Three things that make agents converge on Jentic-routed access.

Credential isolation

Buffer OAuth 2.0 access tokens are stored encrypted in the Jentic vault (MAXsystem). Agents receive tokens with posting permissions — raw client secrets and authorization codes never enter the agent's context.

Intent-based discovery

Agents search by intent (e.g., 'schedule a social media post') and Jentic returns the matching POST /updates/create operation with its full request schema including profile_ids, text, and scheduling fields, so the agent can queue content without browsing Buffer's docs.

Time to first call

Direct Buffer API integration: 1-3 days for OAuth setup, profile connection, and queue management logic. Through Jentic: under 1 hour — search for the operation, load the schema, execute.

Related APIs

Alternatives and complements available in the Jentic catalogue.

Complementary

Twitter API v2

Direct Twitter access for real-time features like streams and search not available through Buffer's scheduling layer

Use Twitter API directly when the task requires real-time tweet search, streaming, or direct message access — Buffer handles scheduled publishing but not real-time interactions

Complementary

LinkedIn API

Direct LinkedIn access for company page management and UGC posts beyond Buffer's scheduling capabilities

Use LinkedIn API directly when the task requires organization statistics, member profile access, or social actions (comments/likes) that Buffer's publishing-focused API does not cover

Alternative

Sprout Social API

Enterprise social media management platform with deeper analytics and team collaboration features

Choose Sprout Social when the task requires enterprise-grade social analytics, team approval workflows, or social listening capabilities beyond Buffer's scheduling focus

FAQs

Specific to using Buffer API API through Jentic.

What authentication does the Buffer API use?

The Buffer API uses OAuth 2.0 authorization code flow. After authorization, you receive an access_token that must be included as a query parameter or in the Authorization header for all requests. Tokens do not expire but can be revoked via POST /user/deauthorize. Through Jentic, OAuth tokens are stored encrypted in the MAXsystem vault — agents receive scoped tokens without handling raw client secrets.

Can I schedule posts to multiple social media platforms at once?

Yes. Use POST /updates/create with an array of profile_ids to schedule the same content to multiple connected profiles (Twitter, Facebook, LinkedIn, etc.) in a single request. Each profile publishes independently according to its configured schedule or the specified scheduled_at timestamp.

What are the rate limits for the Buffer API?

The Buffer API enforces rate limits per access token. Standard limits allow approximately 60 requests per minute across all endpoints. The POST /updates/create endpoint has additional per-profile limits of 100 queued updates maximum. Rate limit headers are not explicitly documented, so monitor for 429 status codes.

How do I schedule a social media post through Jentic?

Install the Jentic SDK with pip install jentic, then search for 'schedule a social media post'. Jentic returns the POST /updates/create operation with the full request schema showing required text, profile_ids array, and optional scheduled_at, media, and shorten fields. Load the schema and execute with your content. Sign up at https://app.jentic.com/sign-up.

Can I manage the order of queued posts?

Yes. Three queue manipulation endpoints are available: POST /profiles/{id}/updates/reorder lets you specify a complete ordering of update IDs, POST /updates/{id}/move_to_top moves a single update to publish next, and POST /profiles/{id}/updates/shuffle randomizes the entire queue order.

Does the Buffer API provide posting analytics?

Yes. GET /profiles/{id}/updates/sent returns all published posts with their engagement statistics. Each sent update includes retweets, favorites, clicks, reach, and other platform-specific metrics. Use GET /links/shares to check how many times a specific URL has been shared across the Buffer network.
