Your content rarely starts in PostQueen. It starts in a sheet a client fills in, in the post you publish on Friday, in a scenario you built two years ago. Five routes put her inside the tool you already run. Content from AI, an RSS feed or a spreadsheet reaches PostQueen through Create Post and is scheduled to every channel at once ## Pick your route A community node with seven ready-made operations, from scheduling to video generation Webhooks by Zapier in both directions, until the native app ships The HTTP module for scenarios, plus a custom webhook coming back An HTTP call to your endpoint the moment a post goes live She watches a feed hourly and drafts the newest item for you | | Direction | Needs a workflow tool | | ----------------------- | -------------------- | --------------------- | | **n8n · Zapier · Make** | your tool calls her | yes | | **Webhooks** | she calls your stack | no | | **RSS AutoPost** | she moves on her own | no | ## What all five share **One API key.** In [app.postqueen.ai](https://app.postqueen.ai), open **Settings › Developers › Public API** and click **Reveal**. Send it as `Authorization: YOUR_API_KEY`, with no `Bearer` prefix. The n8n credential sends it for you once saved. Everything here speaks to the [Public API](/public-api/introduction) that also sits behind the [CLI](/cli/introduction) and [MCP](/mcp/introduction), so the result never depends on the route. The create-post endpoint allows **30 requests per hour**. A chatty trigger reaches that faster than you would expect, so filter or delay a busy source. ## Self-hosting Your own domain changes the address and nothing else. | Where | Set it to | | ------------------------ | --------------------------------------------- | | n8n credential **Host** | `https://postqueen.example.com/api` | | Zapier and Make base URL | `https://postqueen.example.com/api/public/v1` | | Hourly ceiling | the `API_LIMIT` environment variable | Webhooks and AutoPost live in your instance's own settings, and with billing switched off the plan checks are skipped, so both tabs are there. AutoPost calls OpenAI for captions and pictures, so set `OPENAI_API_KEY` before turning those on, or leave them off and run the feed with no AI key at all.
