Build
Automations
Publish from a new blog post, a product launch or a spreadsheet row. Any tool that can send an HTTP request can schedule posts with a project API key.
What you need
A project API key (ptk_…) from Connect AI → Project keys (Conectar IA → Claves de proyecto), and the channel IDs from GET /api/v1/channels. See the Quickstart.Every recipe below sends the same request:
- Method
- POST
- URL
- https://postika.app/api/v1/posts
- Header
- Authorization: Bearer ptk_…
- Body
- JSON: content, channel_ids, when, mode
Body
{
"content": "New on the blog: How we cut our build time in half",
"channel_ids": [
"8d0c6f8e-2b7a-4c1e-9f43-2f1d7a8b5c10"
],
"when": "2026-11-12 09:30",
"mode": "approval"
}when is in the project's local time. Use approval while you test so nothing goes out without you.

}AI Agent with MCP
To let an n8n AI Agent decide what to post, add an MCP Client Tool to the agent with endpoint https://postika.app/api/mcp, transport HTTP Streamable and Bearer authentication with your key. The agent gets the five Postika tools.
