To secure VTEX API keys in a headless storefront, use a Backend-for-Frontend (BFF) to proxy private API calls and manage credentials server-side. This prevents sensitive keys from leaking to the client browser.

Managing VtexIdclientAutCookie server-side is the best way to handle shopper sessions. The BFF architecture securely routes requests and handles session validation without exposing cookies to the public client.

You separate public and private endpoints in a VTEX BFF by routing them through /pub and /pvt paths respectively. This modular setup ensures only authorized requests access sensitive private API operations.

Yes, you need a BFF to proxy VTEX API calls when building a headless storefront. It acts as a secure middleware layer that validates requests, handles sessions, and protects API keys from public exposure.

Yes, using a BFF proxy prevents VTEX API key leakage by keeping segregated keys on the server. The proxy validates requests and handles authentication, ensuring keys never reach the frontend client.
