# Maintain Account Closures
source: https://developer.mastercard.com/payment-account-management/documentation/use-cases/closures/index.md

**Scenario** : A cardholder has either lost/stolen his card or devcides to close his account with the institution and as a result their debit card is closed as well.  

**Description** : In this use case, `/closeAccount` API is used to notify all three Mastercard systems. It will close an account in ABU, delete the associated active and suspended tokens in the Token Vault and delete the associated PAR in the PAR Vault. To confirm successful response, the `/requestStatus` API is then sent.

### Consuming Systems {#consuming-systems}

* Account Billing Updater
* Mastercard Digital Enablement Systems (Token Vault)
* Payment Account Reference Vault

### Sequence {#sequence}

Diagram closeAccount2

1. Issuer sends a `/closeAccount` request to PAM API.
2. PAM API will publish the update to other Mastercard systems such as ABU, Token Vault, and PAR Vault.
3. Each of these Mastercard systems will consume this account update.
   1. Par Vault will delete the PAR associated to this card/PAN and send the success response or an error code to PAM API.
   2. Token Vault will delete the tokens and send the success response or an error code to PAM API.
   3. ABU will mark the account as closed and send the success response or an error code to PAM API.
4. Issuer then sends a `/requestStatus` request to confirm if the account was successfully closed in ABU and the update consumed by all the Mastercard systems.
5. PAM API will then confirm this update to the issuer with a `/requestStatus` response with a success or the specific error code received from ABU, PAR Vault, and MDES.

Refer to the integration tutorial for details on how to use these endpoints for closing an account in ABU.
