Developers
Build publishing workflows on Ostuu
Connect ChatGPT to Ostuu with OAuth 2.0, or call the HTTP API from your own application. OAuth is for interactive AI connections. API keys remain the way to authenticate direct integrations.
HTTP API
Read and update brands, destinations, posts, media, preflight results, schedules, and publish jobs from your own application.
MCP
Connect a compatible AI client to https://www.ostuu.com/api/mcp. ChatGPT uses OAuth 2.0. Scripts and other direct integrations keep using a workspace API key. Your client supplies the model.
TypeScript SDK
Call API v1 from server-side TypeScript. The signed-in SDK guide describes the current client. A package release that matches today's API is in progress.
Two ways to connect an assistant
ChatGPT is a verified Ostuu connection. Other assistants are not automatically supported, and this is not an OpenAI partnership.
- OAuth 2.0 lets someone sign in and approve one workspace.
- You choose which permissions that application can use, and you can revoke them.
- API keys stay available for existing scripts and direct MCP clients.
What an agent can do
Generate the content in your own client. Then use Ostuu to upload the visuals, create the posts, preflight every one, and schedule the campaign.
- 1Generate the copy and visuals in your AI client.
- 2Upload those visuals and create the posts in Ostuu.
- 3Preflight each post against its destinations.
- 4Schedule the campaign through Ostuu.
Guides for authentication, API keys, MCP clients, and the API reference are in the developer documentation. You will sign in to read them and to create a key.
