One publishing surface
Build your workflow against one API instead of maintaining a separate implementation for each social platform.
Social media scheduling API
Schedule social posts programmatically through one API.
Connect your channels once, then let your backend, automation or AI agent create and schedule posts without rebuilding every network integration yourself.
REST API, MCP and SDK access are included on every current PostSider plan.

}One scheduling request. Same publishing system as the PostSider calendar.
Why use a unified API
Keep social publishing out of your integration backlog.
The hard part is not sending JSON. It is maintaining authentication, platform-specific payloads, scheduling state and delivery logic across every network you support.
Scheduled publishing
Send the post, target channel and UTC publish time from your own application or automation.
30+ destinations
Use the same connected-channel system across mainstream social, video, community and publishing destinations supported by PostSider.
Agent-ready
Call the REST API yourself or expose the same workflow to compatible AI agents through PostSider's MCP server.
Typed SDK path
Move from raw HTTP to the TypeScript and Node.js SDK when the integration becomes part of a larger application.
Webhooks when polling stops scaling
Use webhooks on Pro and Ultimate for event-driven workflows that need publishing updates pushed back to your system.
Choose the caller
REST, MCP and SDK are three doors into the same publishing layer.
REST API
Use raw HTTP when your code already knows exactly what action it needs to perform.
View REST API →MCP
Let a compatible AI client discover publishing actions and call them as tools instead of driving a browser.
View MCP setup →SDK
Use typed helpers when you want the same REST API with autocomplete and a library-native developer experience.
View SDKs →Common API use cases
Use PostSider as the publishing layer behind your own workflow.
Turn releases, changelog entries or product events into scheduled social posts.
Keep your own interface and business logic while PostSider handles the connection to social networks.
Let an agent draft and schedule through MCP or REST while humans can still inspect the calendar.
Batch repetitive client publishing work while preserving the review and approval workflow around it.
Trigger distribution when new content ships instead of manually copying it into each social network.
Use cron jobs or queue workers to build predictable social publishing into an existing system.

FAQ
Social media scheduling API questions.
What is a social media scheduling API?
A social media scheduling API lets your application create and schedule posts programmatically instead of relying on a person to publish them manually. A unified API can also hide the differences between multiple social networks behind one integration layer.
Can PostSider schedule posts through an API?
Yes. PostSider exposes a REST API for creating and scheduling social posts, working with connected channels and reading publishing state. The exact request fields are documented in the public API reference.
Which social networks does the PostSider API work with?
PostSider supports 30+ publishing destinations across social networks, video platforms, communities and publishing platforms. Your API workflow uses the same connected channels as the PostSider application.
Can an AI agent use the same publishing API?
Yes. An AI agent can use the REST API directly, or connect through PostSider's MCP server so it can discover publishing tools as named actions.
Does PostSider provide webhooks?
Webhooks are currently included on Pro and Ultimate plans for event-driven workflows. REST API, MCP and SDK access are included across the current PostSider plans.
Is there an SDK for the PostSider API?
Yes. PostSider provides an official TypeScript and Node.js SDK, and an OpenAPI specification for teams that want to generate clients in other languages.
