What environment variables are required?

You must set AUTHORIZE_NET_API_LOGIN_ID, AUTHORIZE_NET_TRANSACTION_KEY, and optionally AUTHORIZE_NET_SANDBOX (set to "true" for sandbox mode).

How does sandbox vs production work?

Sandbox testing uses Authorize.net sandbox credentials and the AUTHORIZE_NET_SANDBOX env variable. For production, switch the base URL in authorizeNetHandlers.ts and use live credentials.

Where is security discussed?
