Exchange money

Exchange money using one of these methods:

  • Sell currency: You know the amount of currency to sell. For example, you want to exchange 135.5 USD to some EUR.

    Specify the amount in the from object.

  • Buy currency: You know the amount of currency to buy. For example, you want to exchange some USD to 200 EUR.

    Specify the amount in the to object.

note

You must specify the amount field only once, either in the from object or in the to object.

For more information, see the guides: Exchange money.

Access Token​

Each Business API request must contain an authorization header in the following format to make a call: Bearer <your_access_token>.

The access token will be obtained the first time you set up your application and has an expiration of 40 minutes. During setup, a refresh_token will also be obtained which allows to obtain a new access_token.

danger

Never share your client-assertion JWT (JSON web token), access_token and refresh_token with anyone, as these can be used to access your banking data and initiate transactions.

Access tokens can be issued with four security scopes and require a JWT (JSON Web Token) signature to be obtained:

  • READ: Permissions for GET operations.

  • WRITE: Permissions to update counterparties, webhooks, and issue payment drafts.

  • PAY: Permissions to initiate or cancel transactions and currency exchanges.

  • READ_SENSITIVE_CARD_DATA: Permissions to retrieve sensitive card details.

    caution

    If you enable the READ_SENSITIVE_CARD_DATA scope for your access token, you must set up IP whitelisting. Failing to do so will prevent you from accessing any Business API endpoint.

    IP whitelisting means that you must specify an IP or a set of IPs which will be the only IPs from which requests to the API will be accepted. To do so:

    1. Go to the Revolut Business web app settings -> APIs -> Business API.
    2. Select the corresponding API certificate.
    3. In Production IP whitelist, provide the IP(s) which should be whitelisted, and save.

To configure your JWT and obtain the refresh and first access tokens, complete the following steps:

  1. Sign up for a Revolut Business account
  2. Prepare your Sandbox environment
  3. Make your first API request
