30-Day Free Trial
Login with 1 WhatsApp number to dispatch up to 50 messages per day. Full support for text messages, verification OTPs, images, and PDF invoice documents.
Key Expiry & Stop
After your 30-day trial expires, the API key is automatically paused to prevent unauthorized spam. Renew anytime through your dashboard to re-activate messaging.
