Retrieve end_user balances details given an end_user_id (external_ref).
B2B’s White Label API uses OAuth2. Currently there is only one supported authentication flow:
Every call to the API has to be authenticated with an OAuth2 Token. In order to request this token, you will need to have sandbox or production API Keys (client id and client secret) that will be needed to generate a credential in order to negotiate an ephemeral access token.
Every request must be accompianed by an Authorization
header with a value that follows the following schema: Bearer ACCESS_TOKEN
Indicates End User external_ref.
Allows filtering the returned balances by one or more currencies. If a currency is requested that the account does not support, it will simply be omitted from the response without error.
