The Instant WhatsApp API for Global Authentication.

No Meta business verification. No waiting for approvals. Just create an account, add $10 to your wallet, and get a production-ready API key and endpoint to send WhatsApp OTPs across the globe.

Live in Production in 3 Steps

1

Fund Your Wallet

Login to the dashboard and add a minimum $10 top-up. These are 100% usable funds with zero hidden fees.

2

Get API & Endpoint

Your Master API Key and our simple REST endpoint URL are instantly generated. No complex configurations.

3

Send OTPs Globally

Inject the API into your app, website, or backend, and start delivering WhatsApp OTPs anywhere in the world.

244 Global Destinations

Our API connects you to every country and territory where WhatsApp operates. You can check the exact pricing for all 244 destinations directly on our Pricing Calculator before you send a single message. The cost per OTP is automatically deducted from your wallet based on the destination's official Meta rate plus a fractional routing margin.

High-Speed Golang Backend

Send as many messages as you want, whenever you want. Our routing engine is built entirely on Golang (Go), designed specifically for massive concurrency and low latency. Whether you are sending 100 OTPs a day or bursting 10,000 auth requests per second, our backend processes and routes them to Meta's servers instantly without any bottlenecks.

curl -X POST "https://api.5minutesapi.com/v1/send-otp" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -d '{"to":"971501234567","code":"492011"}'

Real-Time Analytics & Auto-Refunds

Your dashboard gives you a complete, real-time breakdown of your traffic. Track exactly how many OTPs were successfully delivered and how many failed.

Never pay for ghost traffic: If you send an OTP to an invalid number, or a user who doesn't have WhatsApp installed, our system detects the failure via Meta's webhook and refunds the exact cost back to your wallet in milliseconds.
