Close one or more accounts for a given customer. This will set the account status to closed and set the closed_at field on the Retrieve Accounts V3 response.
If an account is already closed, then the request will be ignored, and the closed_at field will remain unchanged.
If a 400 response is returned, any accountIDs or customerIDs not defailted in the error response will have been closed succesfully.
