4. Get the access token

In order to send requests to the API, you must first get your access token.


You must provide the headers and parameters listed below.


You must use a transport certificate and its private key in order to request an access token.

  • For Sandbox testing, you can use the transport.pem certificate file which you obtained in Convert certificates, together with the private key generated in step Generate a CSR.

  • For Production, you must use a valid OBIE or eIDAS transport certificate from a regulated Certificate Authority (CA), and its corresponding private key.


Revolut Open Banking API servers use certificates issued by Open Banking Limited.

You can find the root and issuing certificates here if you need to add them to your truststore.


  • Content-Type: application/x-www-form-urlencoded


  • grant_type: Must be set to client_credentials to get the access token.
  • scope: Must be set to accounts.



The parameters -k or --insecure are not necessary if you added Open Banking Root and Issuing certificates to your truststore.

curl -k --cert transport.pem --key private.key \
--location -X POST '' \
--header 'Content-Type: application/x-www-form-urlencoded' \
-d 'grant_type=client_credentials' \
-d 'scope=accounts'


The response contains the following JSON object:

"access_token":"<access token>",

What's next

Use this access token as the authentication bearer for all subsequent requests to the API, as described in the Tutorials section. Once your token expires, repeat the steps above to create a new token.
