The OptiPub API gives you programmatic access to the OptiPub platform — manage subscribers, send messages, create content, build segments, and automate your publishing workflows.

The API follows REST conventions. Resources are accessed via standard HTTP methods (GET, POST, PUT, DELETE) and all responses are returned as JSON.

Base URL

https://{APP_DOMAIN}/api/3.2

Replace {APP_DOMAIN} with your OptiPub application domain (e.g. yourapp.app.optipub.com).

Authentication

Include your API key in the Authorization header of every request:

Authorization: Bearer YOUR_API_KEY

See Creating an API Key for setup instructions.
