      description: 'Sandbox-only endpoint with three modes:


        **Simulate bank transfer processing** — Omit the body or send an empty JSON object. Processes or fails

        the last 500 bank transfers on the authorized application or Sandbox account (and initiated micro-deposits).

        If webhooks are configured, events are delivered. If a bank-to-bank transaction involves two users,

        call this twice to process debit and credit sides. Returns **200** with a HAL document including `total`.


        **Simulate VAN (virtual) transfers** — Send a JSON body with `type` set to `virtual` and a `transfers`

        array (up to 10 items). External transfers are created and processed immediately. Returns **202 Accepted**.


        **Simulate verification directives** — For a business Verified Customer in **`retry`** or **`document`**

        status, send `type`: `customer-verification`, `_links.customer.href` pointing at that customer, and

        `errorCode` set to one of: `PersonalIDRequired`, `POBoxNotAllowed`, `AddressNotAssociatedWithBusiness`,

        `EINDocumentRequired`. Returns **200** with HAL `_links.self` and `errorCode`. Then **GET** the Customer;

        the same code appears in `_embedded.errors` for end-to-end testing.'
