### Understanding Accounts {#understanding-accounts}

Customer account records have a lot of different data points that can be used in your application. There are a few important pieces of information to note that can be used to properly identify accounts you want to use in your application, and some data points that will help you best organize account data inside your application. Understanding how to manage these accounts is covered here.

#### Customer Account Operations {#customer-account-operations}

After a customer has added accounts, the list of accounts they have added can be retrieved, and removed using these operations.
Tip: Access to any customer account data requires the **Consent Receipt Id** the customer has given when linking these accounts . **Consent Receipt Id** is obtained through [Consent Notification](https://developer.mastercard.com/open-finance-au/documentation/consent/consent-notifications/index.md) as part of accounts linking.
