What is an API key and where can I find it?

An API key is a string of characters that is used to connect your merchant account with your website or plugins. You do not need an API key if you just want to use payment requests or invoices.

To locate your API key:

• Log in to your Revolut Business portal.
• In the top left corner, click your account name, then click Merchant API.
• Under the Production API Key section you will find the API key.
• Click "Generate" button to create your unique API key (only if it is your first time using the API key).

You can also use this link to directly open the Merchant API page.
