EngageLab OTP API Skill

This skill enables interaction with the EngageLab OTP REST API. The OTP service handles one-time password generation, multi-channel delivery (SMS, WhatsApp, Email, Voice), verification, and fraud monitoring.

It covers six areas:

1. OTP Send — Platform-generated OTP code delivery
2. Custom OTP Send — User-generated OTP code delivery
3. OTP Verify — Validate OTP codes
4. Custom Messages Send — Send custom template messages (notifications, marketing)
5. Template Management — Create, list, get, and delete OTP templates
6. Callback & SMPP — Webhook configuration and SMPP protocol integration

• otp_client.py — Python client class (EngageLabOTP) wrapping all API endpoints: send_otp(), send_custom_otp(), verify(), send_custom_message(), and template CRUD. Handles authentication, request construction, and typed error handling. Use this as a ready-to-run helper or import it into the user's project.
• verify_callback.py — HMAC-SHA256 signature verifier for incoming OTP callback webhooks. Parses the X-CALLBACK-ID header and validates authenticity. Drop into any web framework (Flask, FastAPI, Django) to secure callback endpoints.
