Public API Reference (2025-07-30)

The Zephr Public API provides common client-side actions tied to a session cookie. Unlike the Admin API, neither users nor other resources can be dereferenced; the only data that can be accessed is owned by the user who is currently signed-in. This design is used to protect other users from malicious attacks.

You can find the base URL for the Public API by navigating to your site domains. To do this, select Sites from the Delivery menu, select your site, and then click the Site Domains button. The base URL is the Live domain.

Zephr forms use the Public API by default, with relative URLs based on the base URL.

Authentication

Operations

Start the passwordless authentication flow

Request

Starts the passwordless authentication flow by sending an email to the user with a sign-in link. When the user clicks the link, they are directed to GET /blaize/token-exchange?token=..., which authenticates them automatically. IMPORTANT: Passwordless authentication requires the user's email to be verified. This means the user must first receive a separate verification email and click the link to confirm their email address. Verification can be triggered by sending a POST request to the appropriate endpoint.
