Revolut Business API reference

Introduction to the Business API

As a Revolut Business customer, you can use the Business API to automate your own business processes.

For example, you can view accounts, add counterparties, make payments or currency exchanges without manual effort in the WebUI interfaces. This saves time and reduces costs and errors.

Sign up for a Revolut Business account to start using the Business API. You can also get a Sandbox account to test your application before you pushes the changes to production.

Get Started

The Business API is available only to Revolut Business account holders. You must sign up to start using the API.

Prepare your Sandbox environment

The Sandbox environment is a non-production environment that you can use to start working with the Business API.

To prepare your Sandbox environment, create a Sandbox account first, and then you can use mock data and test your application safely in a simulated environment.

You can sign up for a Sandbox account in a similar way you apply for your Revolut Business account.

Create a Sandbox Business account

Note: To use the Business API with your Sandbox account, change the address of the endpoints that you want to test from https://b2b.revolut.com/api/1.0/ to https://sandbox-b2b.revolut.com/api/1.0.

Make your first API request

To start making your first API request, you must complete the initial setup, which is shown in the following high-level procedure:

Upload your certificate to authorize your application to access your Revolut Business account via the Business API.
Consent the application and you obtain an authorization code and the client ID.
Provide a client assertion JWT to exchange your authorization code for access token.
Exchange authorization code for access token that you can use to access the Business API.
When the access token expires, request a new access token.
Try your first API request to get a list of all your accounts.

After you complete and validate the setup, you can make different requests to the Business API.

1. Upload your certificate

Authorize your application to access your Revolut Business account via the Business API. To do this, you need to first upload your certificate on the API settings page of the Revolut Business portal.

Before you begin

Create a private and public key

$ openssl genrsa -out privatekey.pem 1024
$ openssl req -new -x509 -key privatekey.pem -out publickey.cer -days 1825

Create a public/private key pair, and then copy and paste the publickey.cer into the required field when you complete the following steps.

Procedure

Log in to your Revolut Business portal, and go to Settings > API.
Click Add certificate.
Copy and paste the publickey.cer to the X509 public key field.
Specify the OAuth redirect URI. This is the URL where you are redirected after you consent the application to access your Revolut Business account.
Click Continue.

You are directed to the API Certificate page where you need to consent the application.

Sample Confirmation URL

https://business.revolut.com/app-confirm?client_id=n0z4gsis9cGhwaYxxMlLQ7FScijU6NuqZV1MEP8YQI0&redirect_uri=http://revolutredirect.com/&response_type=code#authorise

Sample Redirect

https://www.revolutredirect.com/?code=oa_prod_vYo3mAI9TmJuo2_ukYlHVZMh3OiszmfQdgVqk_gLSkU

On the API Certificate page, get your client ID from the ClientId field.
Click Enable API access to your account. You are redirected to the /app-confirm URL where you grant your application to access your account via the Business API.

Note: You can also see the client_id in the app-confirm URL. Check the sample confirmation URL on the right.
Click Authorise. This triggers two-factor authentication process. On successful authorization, you are redirected to the OAuth redirect URI tht you specified.
Get the authorization_code from the redirect URI. Check the sample direct on the right.

3. Generate a client assertion

JWT Header

{
  "alg": "RS256",
  "typ": "JWT"
}

JWT Payload

{
  "iss": <insert your_domain>,
  "sub": <insert client_id>,
  "aud": "https://revolut.com",
  "exp": <insert expiry_date>
}

Generate a client-assertion JWT that you use to exchange your authorization code for access token. The client-assertion JWT should be signed with your private key.

Ensure that the parameters meet the following format. Check the JWT header and the payload examples on the right.

Field	Description	Required	Schema
`iss`	Domain from `redirect_url` (without `http://`)	Yes	Text
`sub`	Your `client_id`	Yes	Text
`aud`	`https://revolut.com`	Yes	Text
`exp`	JWT expiration date	Yes	UNIX timestamp in seconds

4. Exchange authorization code for access token

Exchange for an access token

curl https://sandbox-b2b.revolut.com/api/1.0/auth/token \
  -H "Content-Type: application/x-www-form-urlencoded"\
  --data "grant_type=authorization_code"\
  --data "code=<insert authorisation_code>"\
  --data "client_id=<insert client_id>"\
  --data "client_assertion_type=urn:ietf:params:oauth:client-assertion-type:jwt-bearer"\
  --data "client_assertion=<insert JWT>"

curl https://b2b.revolut.com/api/1.0/auth/token \
  -H "Content-Type: application/x-www-form-urlencoded"\
  --data "grant_type=authorization_code"\
  --data "code=<insert authorisation_code>"\
  --data "client_id=<insert client_id>"\
  --data "client_assertion_type=urn:ietf:params:oauth:client-assertion-type:jwt-bearer"\
  --data "client_assertion=<insert JWT>"

Response

{
  "access_token": "oa_sand_rPo9OmbMAuguhQffR6RLR4nvmzpx4NJtpdyvGKkrS3U",
  "token_type": "bearer",
  "expires_in": 2399,
  "refresh_token": "oa_prod_hQacSGnwx-luIfj3dlVByrytVV9rWAnyHkpJTwG_Tr8"
}

Use the authorization_code, client_assertion, and client_id generated from the previous steps to exchange for an access token that you can use to access the Business API.

Request fields (URL-encoded)

Field	Description	Required	Schema
`grant_type`	The OAuth grant type: `authorization_code`.	Yes	Text
`code`	The authorization code.	Yes	Text
`client_id`	The application ID.	Yes	Text
`client_assertion_type`	The type of the client assertion: `urn:ietf:params:oauth:client-assertion-type:jwt-bearer`.	Yes	Text
`client_assertion`	The JWT token that you generated.	Yes	Text

5. Refresh access token

Refresh access token

curl https://sandbox-b2b.revolut.com/api/1.0/auth/token \
  -H "Content-Type: application/x-www-form-urlencoded"\
  --data "grant_type=refresh_token"\
  --data "refresh_token=<insert refresh_token>"\
  --data "client_id=<insert client_id>"\
  --data "client_assertion_type=urn:ietf:params:oauth:client-assertion-type:jwt-bearer"\
  --data "client_assertion=<insert JWT>"

curl https://b2b.revolut.com/api/1.0/auth/token \
  -H "Content-Type: application/x-www-form-urlencoded"\
  --data "grant_type=refresh_token"\
  --data "refresh_token=oa_prod_gg-_wDV66wYfKKpnF4RIrpOZs2oPTwNp4TXOra5pS0g"\
  --data "client_id=<insert client_id>"\
  --data "client_assertion_type=urn:ietf:params:oauth:client-assertion-type:jwt-bearer"\
  --data "client_assertion=<insert JWT>"

Response

{
  "access_token": "oa_prod_rPo9OmbMAuguhQffR6RLR4nvmzpx4NJtpdyvGKkrS3U",
  "token_type": "bearer",
  "expires_in": 2399
}

After the access token expires, use the refresh_token to request a new one.

Note: For businesses on the freelancer plan, the refresh token is terminated every 90 days to ensure compliance to PSD2 SCA regulations.

Therefore, you must authorize the API to access your account once more and request a new access token.

Request fields (URL-encoded)

Field	Description	Required	Schema
`grant_type`	The OAuth grant type: `refresh_token`.	Yes	Text
`refresh_token`	The refresh token.	Yes	Text
`client_id`	The application ID.	Yes	Text
`client_assertion_type`	The type of the client assertion: `urn:ietf:params:oauth:client-assertion-type:jwt-bearer`.	Yes	Text
`client_assertion`	The JWT token that you generated.	Yes	Text

Create a counterparty

To make a fund transfer or payment, add the counterparty that you intend to transact with.

Depending on whether a counterparty has a Revolut account and which country a counterparty account is based on, the fields that you need to specify are different.

Notes: It is recommended to utilise all available address fields when creating a counterparty and accurately define either individual_name or company_name field for individuals and companies respectively. This significantly reduces the risk of any disruption to payments made via API.

Add a Revolut counterparty

Add a Revolut user as counterparty

curl -X POST https://sandbox-b2b.revolut.com/api/1.0/counterparty \

  "updated_at": "2017-12-19T15:58:34.485Z"
}

If a counterparty has a Revolut account, you need to only provide the phone number, and you don't need full account details to add. However, if you add full account details, this also works.

Create a payment

This tutorial walks you through the steps to make an instant payment and schedule a payment.

An incoming or outgoing payment is represented as a transaction. A transaction is processed in two stages:

A transaction is created,
The transaction is processed in either of the following ways:

Credit/debit on both sides of the transaction made between Revolut accounts.
Posted to an external payment network, for example, Faster Payments, SEPA, SWIFT, etc.

If the payment is made to an external payment network, when the transaction is created, it has the the pending state. When it’s processed, it can have one of the following states:

completed
failed
reverted
declined

If the payment is made between Revolut accounts, the transaction is executed instantly, and skips the pending state.

}

Create a payment using the /pay endpoint.

If you make the payment to another Revolut account, either business or personal, the transaction is executed instantly.

Note: When you make the payment to a business counterparty, you must specify the account_id under receiver.

Tip: To avoid submitting duplicate payments because of an error in your code, ensure that request_id is unique for each payment and has persisted on your side previously.

You can schedule payments between Revolut accounts for up to 30 days ahead. Scheduling payments to an external payment network is not supported at the moment.

Scheduled payments must be in the currency of the account that you pay from. To schedule a future payment, as opposed to immediate execution, add the schedule_for field in the POST /pay request:

Field	Description	Format
`schedule_for`	The future date and time that you schedule the payment.	ISO date/time

Learn how to retrieve the historical transactions based on the provided query criteria.

The API returns a maximum of 1,000 transactions per request.

Filter transactions

Get a filtered transaction list

curl https://sandbox-b2b.revolut.com/api/1.0/transactions? \
  counterparty=5138z40d1-05bb-49c0-b130-75e8cf2f7693 \
  &from=2017-06-01 \
  &to=2017-06-10 \
  &count=10 \
  &account=041c7846-4c5e-44af-b8f6-206f61e9f60a \
  -H "Authorization: Bearer <your access token>"

curl https://b2b.revolut.com/api/1.0/transactions? \
  counterparty=5138z40d1-05bb-49c0-b130-75e8cf2f7693 \
  &from=2017-06-01 \
  &to=2017-06-10 \

  &account=041c7846-4c5e-44af-b8f6-206f61e9f60a \
  -H "Authorization: Bearer <your access token>"

You can filter the transactions returned by adding one or more of the following parameters to the URL.

The following table lists the parameters that you can optionally add as filters:

Parameter	Description	Required	Schema
`from`	The date and time you retrieve the historical transactions from.	No	ISO date/time
`to`	The date and time you retrieve the historical transactions to. The default value is now.	No	ISO date/time
`counterparty`	The ID of the counterparty.	No	UUID
`account`	The account ID.	No	UUID
`count`	The number of the historical transactions to retrieve. The maximum number is 1,000. The default number is 100.	No	Number
`type`	The type of the historical transactions to retrieve, which can be `atm`, `card_payment`, `card_refund`, `card_chargeback`, `card_credit`, `exchange`, `transfer`, `loan`, `fee`, `refund`, `topup`, `topup_return`, `tax`, or `tax_refund`.	No	Text

Pagination of transfers

The /transactions endpoint supports time-based pagination. It returns transactions in reverse chronological order (from <= created_at < to) limited to most recent count entities. Thus, to get the next page of results, you should set parameter to with the value of created_at last item of the previous page.

You can exchange the money in either of the following cases:

You know the amount of currency to sell, for example, exchange 100.0 USD to some EUR. Then, specify the amount in the from object. Check the example on the right.
You know the amount of currency to buy, for example, exchange some USD to 100.0 EUR. Then, specify the amount in the to object.

Restriction: You can specify the amount field only once either in the from object or in the to object.

To check the exchange rate and fees for the operation, use the /rate endpoint.

Work with webhooks

A webhook (also called a web callback) allows your system to receive updates about your account to an HTTPS endpoint that you provide. When a supported event occurs, a notification is posted, via HTTP POST method, to the specified endpoint.

If the receiver returns an HTTP error response, there are two more consequent attempts for delivery.

Currently, the following events are supported:

Transaction Creation (TransactionCreated)
Transaction State Change (TransactionStateChanged)

Usage and limits

In order to ensure safe and fair resource sharing, we define the following usage limits:

A maximum of 60 requests per minute for a single business

As businesses on a Freelancer plan, you are also required to ask users for explicit authorization to access their account via the API every 90 days.

This means that access tokens expire every 90 days and you (or your users) will need to authorize access to the app once more. This is due to the recent PSD2 SCA regulations.
