If your Merchant Account application has been successful, you’ll receive an email from us. As soon as you receive this email, you can begin using your Merchant Account by integrating the Revolut payment widget into your website’s checkout page. You can also send your customers a payment request link, or install one of our available plugins if you’re using an e-commerce platform.
If you want to accept payments through your website (through either a Revolut Checkout solution or one of the official plugins), you’ll need to use a Merchant API key – which you can find under the API option of the Merchant tab in your Revolut Business App portal. You can refer to the full Merchant API documentation for details.
