Why does this API matter?

OTPZap provides a public REST API for developers. Generate keys in your dashboard, authenticate via Bearer token, 300 req/min rate limit. Perfect for testing, automation, and growth hacking.

API quick start

• POST /api/v1/order/create with body {server:1, product_id:...}
• GET /api/v1/order/check?order_id=N to poll for OTP
• Header: Authorization: Bearer otpzap_live_xxxxxxxx
• For safe retry, send header Idempotency-Key: unique-string

Best practices

• Use webhooks to avoid polling (set in Developer API → Webhook tab).
• Implement exponential backoff to handle rate limits.
• Do not hardcode API keys, use env vars in production.
• Audit request logs periodically in the dashboard.
