Accounts

API reference for account-related endpoints

PreviousCustomersNextCards

Last updated 1 year ago

Creating a New Account for a Customer

A new account for a customer can be created using the POST endpoint: /customers/{customerId}/accounts. .

Account Entity Updates

Any internal updates to the account entity will be reported through webhook update events. For details on how to set up and manage webhook subscriptions, please refer to Webhooks.

Blockchain Updates

To proceed with account deployment and activation, a challenge issued by the endpoint must be signed and verified (see Blockchain Updates).

Retrieve Account Entities

To retrieve a list of all account entities registered for the programme, make a GET request to /accounts.

Retrieve an Individual Customer's Accounts

To retrieve information about an individual customer's accounts, make a GET request to /customers/{customerId}/account with the customer ID as a path parameter.

Retrieve an Individual Account

To retrieve information about an individual account, make a GET request to /accounts/{accountId}.

Deactivate an Account

To deactivate an account, use a PATCH request to /accounts/{accountId}/deactivate. This action will also deactivate all associated resources, such as cards.

Reactivate an Account

To reactivate a previously deactivated account, use a PATCH request to /accounts/{accountId}/activate.

Closing an Account

An account can be closed and subsequently removed from the programme using a DELETE request to /account/{accountId}. This will also deactivate all associated resources, including cards, and irreversibly deactivate the smart contract associated with it. All data will be preserved for audit and compliance purposes.
