Backend API Reference

You should prefer to use a library over the API directly. If a library for your language doesn’t exist yet, please reach out to support@propelauth.com and we’ll be happy to help.


PropelAuth uses API keys for the backend API. You can manage your API key(s) under the Backend Integration section of your project at https://app.propelauth.com.

PropelAuth expects the API key in an Authorization header like the following:

Authorization: Bearer YOUR_API_KEY


PropelAuth uses a different domain for each application. Your application, for example, will be hosted at https://auth.yourdomain.com. An HTTP Request of /api/v1/example should be https://auth.yourdomain.com/api/v1/example in that case.

You can set your domain under the Go Live section of your project.
