# Product.fetchByMerchantEntitlementId

The `fetchByMerchantEntitlementId` method returns one or more `Product` objects whose entitlement ID assigned by you (`merchantEntitlementId`) matches the input. For example, call this method in response to a customer request for a list of all your products that offer a certain privilege on your site.

## Input

*srd*: sparse response description, a SOAP string (which must be a JSON object), in which you specify the elements you want returned.This parameter enables the calling system to constrain a `method` call to return only components you specify. This gives you greater control over returned content, and improves response time within the Vindicia platform by reducing the processing needed for the call.

Some fields are required, either practically or in the WSDL, and will be returned regardless of the *srd*. A null *srd* returns the complete response.

*merchantEntitlementId*: your entitlement ID (`merchantEntitlementId`), which serves as the search criterion.

## Output

*return*: an object of type `Return` that indicates the success or failure of the call.

*products*: an array of one or more `Product` objects whose entitlement ID assigned by you (`merchantEntitlementId`) matches the input.

## Returns

In addition to those listed in [The Return Object](The_Return_Object), this call returns:

| Return Code | Return String |
| - | - |
| `400` | `Must specify entitlement id.` |
| `404` | `Could not load product for entitlement id *input-merchant-EntitlementId*.` |

## Example

```

// Create a SOAP caller product object
$prod = new Product();

$response = $prod->fetchByMerchantEntitlementId
      ('PremiumVideoContentAccess');

if($response['returnCode'] == 200) {
   $fetchedProducts = $response['data']->products;

   // process fetched products here
   if ($fetchedProducts != null) {
      foreach ($fetchedProducts as $fetchedProd) {
         // process a fetched product here
      }
   }
}
```
