📄 Description

Fixes: https://github.com/better-auth/better-auth/issues/6938

Summary by cubic

Standardized API error responses to always include a machine-readable code, and surfaced plugin error codes to clients for consistent handling.

  • New Features

    • Introduced APIError in @better-auth/core/error with from and fromStatus helpers.
    • Added isAPIError utility and updated docs to use it for safe error detection.
    • defineErrorCodes now returns { code, message }; BASE_ERROR_CODES expanded (origin/callback/redirect, email verification, sessions, etc.).
    • Updated all routes and plugins to return consistent { code, message } errors.
    • Origin/callback/redirect/errorCallbackURL/newUserCallbackURL validation now throws specific error codes.
    • Exposed error codes to clients via $ERROR_CODES across core plugins (admin, anonymous, api-key, email-otp, generic-oauth, multi-session, organization, phone-number, two-factor, username), plus Stripe and Passkey.

  • Migration

    • Client code should read error.code alongside error.message in responses.
    • Use isAPIError instead of instanceof checks when handling errors.
    • Custom plugins: update $ERROR_CODES to the new shape { code, message } and use defineErrorCodes accordingly.
    • When throwing errors in custom code, use APIError.from(status, errorCode) or APIError.fromStatus(status).

Written for commit 7c39df9b61. Summary will update automatically on new commits.
