Connect channels once
Authorize social accounts in PostSider so your application can publish through one unified layer instead of managing every provider connection itself.

How it works
Use one publishing layer across your workflow.
The hard part of multi-network publishing is not sending content. It is maintaining authentication, provider differences, scheduling state and delivery across every destination.
Send content to one publishing API
Create drafts, scheduled posts or immediate publications with one API surface that sits above the supported social networks.
Use the interface that fits the workflow
Call REST from your backend, use the SDK in application code or expose the same publishing actions to compatible AI agents through MCP.
Track delivery and state
Keep publishing state available to your system and use webhooks on supported plans when you need event-driven updates.

FAQ
Common questions.
What is a social media publishing API?
A social media publishing API lets software create, schedule and publish posts programmatically. A unified publishing API can hide provider-specific request shapes behind one integration layer.
What is the difference between a publishing API and a scheduling API?
A publishing API covers creating and sending social content broadly, while a scheduling API emphasizes future publish times and queue management. In PostSider both use the same underlying publishing system.
Can one API publish to multiple social networks?
Yes. PostSider provides one publishing layer for connected destinations so your application does not need a separate implementation for every supported network.
Can I use the publishing API from an AI agent?
Yes. Agents can call the REST API directly or use MCP when tool discovery is useful.
