An error has occurred: Unmarshalling Error: For input string: "param1"

[Daniel Gómez]

Hi there,

I have started using AdWords API, so far I have been able to use all the Basic Operations. However now I am trying to use AdParameteres for the Ads been unsuccessful so far. 

I have created a campaign, an Ad group, 4 keywords and 1 ad.

The Ad:

Headline: This test title

description1: This test {param1:$20}

description2: for ads {param2:50}

displayUrl: www.example.com

url: http://www.example.com

The code I am using is:

  $adParamService = $user->GetService('AdParamService', 'v201206');

  // Create ad parameters.

  $adParam1 = new AdParam($adGroupId, $keywordId, '$80', 1);  //keywordId existing under the same AdGroup

  $adParam2 = new AdParam($adGroupId, $keywordId, '18', 2);   //keywordId existing under the same AdGroup

  // Create operations.

  $operation1 = new AdParamOperation($adParam1, 'SET');

  $operation2 = new AdParamOperation($adParam2, 'SET'); 

  // Make the mutate request.

  $adParams = $adParamService->mutate(array($operation1, $operation2));

  // Display results.

  foreach ($adParams as $adParam) {

    printf("Ad parameter with insertion text '%s' and parameter index '%s' "

        . "was set.\n", $adParam->insertionText, $adParam->paramIndex);

  }

try {

  // Get AdWordsUser from credentials in "../auth.ini"

  // relative to the AdWordsUser.php file's directory.

      $user = new AdwordsUser(

'./auth.ini',     // $authenticationIniPath

null,             // $email 

null,             // $password

null,             // $developerToken

null,             // $applicationToken

null,             // $userAgent

null,             // $clientId

'./settings.ini' // $settingsIniPath

);

  // Log every SOAP XML request and response.

  $user->LogAll();

  // Run the example.

  SetAdParametersExample($user, $adGroupId, $keywordId);

} catch (Exception $e) {

  printf("An error has occurred: %s\n", $e->getMessage());

}

However every time I try to execute the script it always returns:

An error has occurred: Unmarshalling Error: For input string: "param1" 

I havent been able to find any help on this issue or similar problem.

I would really appreciate your help as I have been on this matter for couple of days already.

Hi,

  Unfortunately, we need to update the AdParam example for PHP.  In v201206, a new field was added to many constructors, which means the examples need to be changed.  You can see more detail here: https://groups.google.com/d/msg/adwords-api/A9m4SB-Jmtc/DhyILEXnqv4J

I'm not sure which parameter needs to be changed, but the problem is you'll need to add an extra parameter to the constructor.  We're working on publishing a fix for this example.
