Connect your social channels
Authorize the accounts in PostSider once. Your application then works with connected channel IDs instead of rebuilding each provider OAuth flow.

How to schedule social media posts with an API
Use one social media scheduling API to connect channels once, create posts from your own application, set a publish time and track what happened after the queue runs.
Start with the social media scheduler API or browse the full developer platform.
How it works
Schedule a social post from code in four steps.
The scheduling part is simple. The important pieces are authentication, the connected channel, the post payload and a reliable way to read publishing state.
Create the post payload
Send the content and target integration through the REST API. The same publishing layer is used by the PostSider calendar and API.
Set the publish time
Use a UTC ISO 8601 timestamp for scheduled posts, or publish immediately when the workflow does not need a queue.
Track the publishing state
Read post status from the API and use webhooks on supported plans when your workflow needs event-driven updates.

FAQ
Common questions.
How do I schedule social media posts with an API?
Connect the target channel, send the post content and channel ID to the scheduling endpoint, and include a future publish time in UTC ISO 8601 format. PostSider then owns the queue and publishing step.
Do I need a separate integration for every social network?
Not when you use a unified API. PostSider keeps provider-specific integrations behind one publishing layer so your application can use one API surface.
Can I publish immediately instead of scheduling?
Yes. The same publishing endpoint can be used for immediate publishing when the workflow does not need a future time.
Can an AI agent use the same scheduling system?
Yes. An agent can call the REST API directly or use PostSider through MCP.
