API Integration
API Authentication
Use Bearer token authentication. Generate API keys from your dashboard under Settings > API Keys. Include the token in the Authorization header: "Authorization: Bearer YOUR_API_KEY". Tokens expire after 90 days.
Sending Messages via API
Make POST requests to /v1/messages endpoint with recipient phone number (E.164 format), message type, and content. For templates, include template name and parameters. Response includes message ID for tracking.
Webhook Configuration
Configure webhooks to receive real-time updates for message status, incoming messages, and delivery receipts. Webhooks must use HTTPS with valid SSL certificate. Include webhook secret for verification.
Troubleshooting
Message Delivery Issues
Common causes: invalid phone number format (use E.164), template not approved, customer hasn't opted in, rate limits exceeded. Check message status via API or dashboard. Error codes provide specific failure reasons.
Rate Limits
Default limit is 1000 messages per second per phone number. For higher volumes, request tier upgrades. WhatsApp also enforces quality-based rate limits - maintain <5% block rate and high engagement to avoid restrictions.
Error Codes
Common errors: 400 (bad request), 401 (unauthorized), 429 (rate limit), 470 (template not approved), 471 (not opted in). Refer to our API documentation for complete error code reference and resolution steps.
