Security

Authentication Methods

WchatPro uses token-based authentication for secure and flexible API access

User Token

Standard

For regular API endpoints, include your user token in the request header. This token provides access to message sending, session management, and user-specific operations.

Authorization: YOUR_USER_TOKEN

// OR as Token header
Token: YOUR_USER_TOKEN

// OR as query parameter
?token=YOUR_USER_TOKEN

Use this method for all message sending, session management, and user-specific operations.

Admin Token

Admin Only

For administrative endpoints (/admin/*), use the admin token. This provides elevated privileges for user management, database operations, and system configuration.

Authorization: YOUR_ADMIN_TOKEN

// Used for endpoints like:
POST   /admin/users
GET    /admin/users
DELETE /admin/users/{id}

Get your admin token from your environment configuration or dashboard settings. Keep it secure and never expose it in client-side code!
