Compare a payment request across execution contexts

Enter your API URL, choose POST, set JSON content type and configure authentication. Inspect status, headers and body. Browser Runner needs the target to allow your origin through CORS; Cloud Runner uses backend connectivity and network protections, so it cannot reach every private service.

POST https://api.example.com/payments
Content-Type: application/json
Authorization: Bearer <your-api-token>

{ "amount": 4900, "currency": "EUR" }
