# Sign In Google

`POST /api/v1/auth/google`

## Request

- Base URL: `https://api.alert.camp` (the document declares no server; this is the origin it was published from)
- URL: `https://api.alert.camp/api/v1/auth/google`
- Auth: none declared

Sign in with Google via backend.

Receives the Google OAuth ID token from the mobile client's native
Google Sign-In SDK, exchanges it for Firebase tokens via REST API
(signInWithIdp). Same pattern as email/password — bypasses the
Firebase SDK's ~4min reCAPTCHA delay on Android.

## Request body

- GoogleSignInRequest: Schema for Google sign-in via backend (reCAPTCHA bypass).
  - `id_token` string, required: Google OAuth ID token
  - `language` string, nullable

## Response `200`

Successful Response

- DirectTokenResponse: Response containing Firebase tokens for direct auth (no SDK needed).
  - `id_token` string, required
  - `refresh_token` string, required
  - `user_id` string, required
  - `email` string, required
  - `display_name` string, nullable
  - `email_verified` boolean
  - `terms_accepted` boolean
  - `terms_previously_accepted` boolean

## Other responses

- `422`: Validation Error
