# Campaign.fetchByCampaignId

Loads a `Campaign.` by its Campaign ID.

## 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.

*campaignId*: the ID of the Campaign you wish to return.

## Output

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

*campaign*: the `Campaign` object whose `CampaignId` matches the input.

## Returns

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

| Return Code | Return String |
| - | - |
| `400` | `Can't load Campaign with ID *input-campaignId*.` |

## Example

```

$camp = new Campaign();
   $response = $camp->fetchByCampaignId('camp132');

   // check $response

   $campaign = $response['campaign'];
   print "got campaign " . $campaign->name() . "\n";
```
