Retrieve a customer's payment method

Authorization​

Each Merchant API request must contain an authorization header in the following format to make a call:

'Authorization: Bearer <yourSecretApiKey>'

Before you start, ensure that you've successfully applied for a Merchant Account in your Revolut Business Account.

The Public key is on the same path in your Revolut Business account as the Secret key. There are two different functions for each:

• Public key should be provided with payment methods at checkout
• Secret key is used as a part of the authorization header for all server calls, e.g., creating order

Complete the following steps to generate the Production API keys (Secret, Public):

1. Log in to your Revolut Business account: Access the Revolut Business log in page and enter your credentials.
2. Navigate to Merchant API settings: Once logged in, access the Merchant API settings page by clicking in the top right corner, then selecting APIs > Merchant API. Here you can access your Production API keys (Public, Secret) specific to your Merchant account.
3. Get API keys: If you're visiting this page for the first time, you'll need to generate your Production API Secret key, click the Generate button.

SSL​

Connection over HTTPS is using SSL authentication. For successful authentication, your system's certificate should be issued by a Public Certificate Authority (PCA) and your system should trust Revolut's public certificate.

Revolut-Pay-Payload-Signature​

Data integrity and authorship will be verified using a payload-based signature. The response of a successful URL registration for address validation (see: Register address validation for Fast checkout) will contain a secret signing key.

The signing key will be used by Revolut to compute a Hash-based Message Authentication Code (HMAC) payload signature whenever the registered URL is called, which should be verified by your backend.
