Authentication
Include your api_key in every protected request. Get the key after signing in to your account.
API Overview
The HANTAR NOW REST API lets authenticated users send WhatsApp content and connect messaging workflows to external systems.
JSON requests
Use POST with Content-Type: application/json. Some endpoints may accept GET, but POST is recommended.
Server-side only
Keep credentials on your backend. Rotate the API key immediately if it is ever exposed.
Before sending: create an account, activate a subscription, connect a WhatsApp device and copy your API key. Recipient and sender numbers should include their country code without spaces or a plus symbol.
