DROP-IN MULTI-PROVIDER SANDBOX

Supported OTP & Messaging Providers

Simulate official telecom APIs and unofficial WhatsApp gateways with 100% payload compatibility. Switch endpoints seamlessly without modifying your application logic.

How Drop-In Replacement Works

Keep your existing SDKs, headers, and request payloads intact. Just point your client base URL to OTP TRAP during development.

Production Base URL

https://api.twilio.com

Connects to live telecom networks and incurs billing charges per message.

OTP TRAP Sandbox Base URL

https://otp.gas.pm/api/provider/twilio

Zero telecom cost. Captures OTP payloads instantly in your local project sandbox inbox.
