The response has a property called status with value _OK_ for successful requests, _fail_ when an error occurs, or warning when some errors are found but a useful result can be returned. If a fail status is returned, a fatal error occurred and the request could not be fulfilled; as a consequence, no product recommendations are included in the response.
The API returns the following information to the client:
| Parameters | Description | Column Title |
