Hi Phil, I've tried this against my test account using the Java client library and here's the sample SOAP request and response that succeeds. You may want to match this with your logs and see if this helps:
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" > xmlns:xsd="http://www.w3.org/2001/XMLSchema" > xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> > <soapenv:Header> > <ns1:RequestHeader > xmlns:ns1="https://adwords.google.com/api/adwords/cm/v201609" > soapenv:mustUnderstand="0"> > > <ns1:clientCustomerId>YOUR_CLIENT_CUSTOMERID</ns1:clientCustomerId> > <ns1:developerToken>YOUR_DEVELOPER_TOKEN</ns1:developerToken> > <ns1:userAgent>YOUR_USER_AGENT</ns1:userAgent> > <ns1:validateOnly>false</ns1:validateOnly> > <ns1:partialFailure>false</ns1:partialFailure> > </ns1:RequestHeader> > </soapenv:Header> > <soapenv:Body> > <mutate xmlns="https://adwords.google.com/api/adwords/cm/v201609"> > <operations> > <operator>ADD</operator> > <operand> > <campaignId>YOUR_CAMPAIGN_ID</campaignId> > <extensionType>CALL</extensionType> > <extensionSetting> > <extensions > xmlns:ns2="https://adwords.google.com/api/adwords/cm/v201609" > xsi:type="ns2:CallFeedItem"> > <ns2:status>ENABLED</ns2:status> > <ns2:feedType>CALL</ns2:feedType> > > <ns2:callPhoneNumber>YOUR_PHONE_NUMBER</ns2:callPhoneNumber> > > <ns2:callCountryCode>YOUR_COUNTRY_CODE</ns2:callCountryCode> > <ns2:callTracking>true</ns2:callTracking> > > <ns2:disableCallConversionTracking>false</ns2:disableCallConversionTracking> > </extensions> > </extensionSetting> > </operand> > </operations> > </mutate> > </soapenv:Body> > </soapenv:Envelope> [main] INFO > com.google.api.ads.adwords.lib.client.AdWordsServiceClient.soapXmlLogger - > SOAP Response: > <?xml version="1.0" encoding="UTF-8" standalone="no"?> > <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"> > <soap:Header> > <ResponseHeader > xmlns="https://adwords.google.com/api/adwords/cm/v201609"> > <requestId>xxxxxxxxxxxxxxxx</requestId> > <serviceName>CampaignExtensionSettingService</serviceName> > <methodName>mutate</methodName> > <operations>2</operations> > <responseTime>332</responseTime> > </ResponseHeader> > </soap:Header> > <soap:Body> > <mutateResponse > xmlns="https://adwords.google.com/api/adwords/cm/v201609"> > <rval> > > <ListReturnValue.Type>CampaignExtensionSettingReturnValue</ListReturnValue.Type> > <value> > <campaignId>YOUR_CAMPAIGN_ID</campaignId> > <extensionType>CALL</extensionType> > <extensionSetting> > <extensions > xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" > xsi:type="CallFeedItem"> > <feedId>FEED_ID_RETURNED</feedId> > <feedItemId>FEED_ITEM_ID_RETURNED</feedItemId> > <status>ENABLED</status> > <feedType>CALL</feedType> > > <ExtensionFeedItem.Type>CallFeedItem</ExtensionFeedItem.Type> > > <callPhoneNumber>YOUR_PHONE_NUMBER</callPhoneNumber> > > <callCountryCode>YOUR_COUNTRY_CODE</callCountryCode> > <callTracking>true</callTracking> > > <disableCallConversionTracking>false</disableCallConversionTracking> > </extensions> > <platformRestrictions>NONE</platformRestrictions> > </extensionSetting> > </value> > </rval> > </mutateResponse> > </soap:Body> > </soap:Envelope> If the issue persists, please send me (*reply privately to author*) the complete SOAP request and response including the clientCustomerId to better check the issue.
