    ## What''s Changed?


    Several endpoints, headers, and fields changed in `v20250224`. For more on breaking changes, refer to our [versioning](/api-reference/platform-api/overview/versioning#v20250224) and [migration](/api-reference/platform-api/overview/migration) guides.


    ## Version Header

    Versions are set in the `Accept-Version` header of API requests. Version numbers correspond with the date associated with that version.  The example below uses the version `v20250224`.


    ```

    -H ''Accept: application/json''

    -H ''Accept-Version: v20250224''

  description: 'The Accounts endpoints represent a user''s checking, savings, mortgage, 401(k), or other types of accounts held by a financial institution.


    An account belongs to a `member`, which represents the user''s overall relationship with a particular financial institution. A checking account may be just one part of a larger relationship that could also include a car loan and a savings account.


    Accounts—and the transactions associated with them—are updated every 24 hours, unless the associated `user` is disabled.


    You can also create manual accounts. Since a manual account has no credentials tied to the member, the account will never aggregate or include data from a data feed. All manual accounts are automatically created under the Manual Institution member.

        - Prevents MX from creating or storing any additional data associated with the account, for example transactions, holdings, statements, and so on.

        - Immediately and permanently deletes all data associated with the account, for example transactions, holdings, statements, etc.

        This action is scoped to the member the account belongs to. This means that if the real world account is connected or reconnected via another member, the block will have no effect on that account.

        This action cannot be taken on accounts where `is_manual` is `true`.

        Objects deleted as a result of blocking an account will issue a webhook for that object with the action set to deleted. For example, account deleted, transaction deleted, and so on. There is no special webhook or action for blocking.
