# post\_\_auth\_google

`POST /auth/google`

*Google OAuth Authentication*

Authenticate user with Google OAuth access token.

This endpoint validates a Google OAuth access token and creates or updates the user account. The system automatically:

* Creates an organization based on the email domain
* Assigns appropriate subscription based on account type
* Handles both personal (gmail.com) and business accounts

**Account Types:**

* **Personal**: gmail.com addresses create personal accounts
* **Business**: Other domains create business accounts with organization name derived from domain

**Requirements:**

* Valid Google OAuth access token
* Token must be obtained through proper OAuth flow

#### TypeScript Client Library

```typescript
private authenticateGoogle = async (data: AuthTypes.GoogleLoginRequest): Promise<any> => {
  this.setAuthToken(data.token);
  return this.makeRequest<any>('auth/google', 'POST', data);
};
```
