Hello,
We've updated to adWords API v201306 and switched from simple login to
OAuth2. We are using one MCC account to access multiple underlying customer
accounts. OAuth2 is working fine when accessing only a few
ClientCustomerId’s.
A “User Rate Limit Exceeded” error is occurring when spawning multiple
processes (lets say 20), getting some info from CampaignService. It seems
that this is not an adWords error, but a Google API error (OAUTH 2), when
refreshing the authtoken to often. This is however handled by the PHP
Client Library…
We’ve made sure that “new AdWordsUser()” and “GetAuthToken()” is called
before the fork and “SetClientCustomerId()” and “GetService()” inside the
fork. It is our understanding that the php client library should handle the
refresh token afterwards…
What are we doing wrong? It is not possible to change the rate limits for
AdWords inside Google API…
Thanks,
Jan
How is the script made up (simplified, just to get the idea):
> <?php
> $user = new AdWordsUser();
> $user->SetOAuth2Info(
> array('client_id' => CONFIG_GAPI_CLIENT_ID,
> 'client_secret' => CONFIG_GAPI_CLIENT_SECRET,
> 'refresh_token' => CONFIG_GAPI_REFRESH_TOKEN)
> );
> $user->SetUserAgent(CONFIG_GAPI_USERAGENT);
> $user->SetDeveloperToken(CONFIG_GAPI_DEVELOPER_TOKEN);
> $user->SetApplicationToken(CONFIG_GAPI_APPLICATION_TOKEN);
> $user->GetAuthToken();
>
> $aAccounts = array('account', 'anotheraccount', 'andanother');
> $children = array();
> $i=0;
> while ($i < count($aAccounts)) {
> $customerId = $aAccounts[$i];
> if (($pid = pcntl_fork()) === 0){
> // Child process
> try {
> $user->SetClientCustomerId($customerId);
> $campaignService = $user->GetService('CampaignService',
> 'v201306');
> $selector = new Selector();
> $selector->fields = array('Status', 'StartDate', 'EndDate',
> 'Id');
> $selector->paging = new Paging(0, 10);
> do {
> // Make the get request.
> $page = $campaignService->get($selector);
> $selector->paging->startIndex += 10;
> } while ($page->totalNumEntries >
> $selector->paging->startIndex);
> } catch (Exception $e) {
> echo $e->getTraceAsString();
> }
> exit();
> }else if ($pid){
> // Parent process
> $children[] = $pid;
> }
> $i++;
> }
> ?>
