Send payment authentication code
Verify API supports Strong Customer Authentication for payments. To begin the process, supply the customer's telephone number (in E.164 format ), the payee that will receive the payment, and the amount (in Euro) of the transaction, to the PSD2 endpoint.
The Verify API returns a request_id. Use this to identify a specific verification request in subsequent calls to the API, such as when making a check request to see if the user provided the correct code.
Replace the following variables in the sample code with your own values:
| Key | Description |
|---|---|
VONAGE_API_KEY | Your Vonage API key (see it on your dashboard). |
VONAGE_API_SECRET | Your Vonage API secret (also available on your dashboard). |
RECIPIENT_NUMBER | The phone number to verify |
PAYEE | Included in the message to describe the payment recipient |
AMOUNT | How much the payment is for (always in Euro) |
