Retrieve Account Failure

GET /v1/clients/{clientId}/accounts/{accountId}?RejectDuplicateCard

Returns

	"type":"http://api.etip-staging.etip.io/errors/bad_request",
	"title":" Bad Request",
	"status":400,
	"detail": "Unhandled tabapay response: 
	{
		\"SC\":410,
		\"EC\":\"3A454002\",
		\"EM\":\"Status\"
	}
}

It was working fine before. Is it because we've hit the endpoint too many times in a time period?
