In this session you will learn how to integrate Salesforce with Google APIs. This will include the required steps to configure a project in the Google Developer Console and setup the OAuth 2.0 authentication handshake. Through samples and code you will learn how to use an OAuth access token to communicate with the Google APIs.

5. Digital Advertising Project
• Doubleclick For Publishers (DFP)
• Advertising management platform
• SOAP API (xml)
• Oauth 2.0 (json)
6. Project Setup
DFP
• Client already has account
• Get Network Code
• Enable API access
Google Developer Console
• Create a project (Google’s “Connected App”)
• Get Client Id and Client Secret
11. Authorization
OAuth 2.0 Handshake
• The Web Server Applications Flow :
– The goal is to get the access token needed to
access the API
– We will store the access token in a custom setting
to be readily available for use in future callouts
– Use the refresh token to get future access
tokens to make the callouts
12. Authorization
Code Sample
• Leverage custom settings to persist authorization related information:
– From API specs
• Endpoint
• Scope
– From Google Console
• Client secret
• Client ID
– From DFP
• Network Code
– From Oauth handshake
• Access token
• Refresh token
13. Initiate OAuth Flow to Get Auth Code
public string getAuthCodeUrl(string redirectUri) {
// use the URL used when authenticating a google user
pagereference pr = new pagereference(custSetting.AuthEndpoint__c + 'auth');
// add the necessary parameters
pr.getParameters().put('response_type', 'code');
pr.getParameters().put('client_id', custSetting.ClientId__c);
pr.getParameters().put('redirect_uri', redirectUri);
pr.getParameters().put('scope', custSetting.Scope__c);
// add required parameters needed to get an be able to use a refresh token
pr.getParameters().put('access_type', 'offline');
pr.getParameters().put('approval_prompt', 'force');
return pr.getUrl();
}
14. Get Access Token – Prep Work
Create internal class in the image of the json response.
public class AccessTokenResponse {
string access_token { get; set; }
string refresh_token { get; set; }
string token_type { get; set; }
integer expires_in { get; set; }
string id_token { get; set; }
public AccessTokenResponse() {}
}
15. Access Token Callout
Once the user authenticated, the returned URL will include an auth code that can
be exchanged for an access token.
public void getAccessToken(string authCode) {
// prepare a string to send to google as body
string body = 'code= authCode;
body += '&client_id= custSetting.ClientId__c;
body += '&client_secret= custSetting.ClientSecret__c;
body += '&redirect_uri= custSetting.redirectUri__c;
body += '&grant_type=authorization_code';
// HTTP callout to Google to exchange the auth code with an access token
// use internal class from last slide to deserialize json response
Authenticate(body);
}
17. Apex Tools for a Google SOAP API
• Force.com Google Data API Toolkit
– Older APIs - authentication methods are deprecated
• Download WSDL
– Difficult to overcome all conversion issues
• Use HTTP callouts
– Make http callouts with SOAP body (XML)
18. Simplified Look at SOAP XML Body
<envelope>
<Header>
<RequestHeader type="SoapRequestHeader">
<authentication type="OAuth">
<parameters>Bearer My_Access_Token</parameters>
</authentication>
<networkCode type="string">
My_Network_Code
</networkCode>
<applicationName type="string">
My_Google_Project_Name
</applicationName>
</RequestHeader>
</Header>
<Body>
My_SOAP_Body
</Body>
</envelope>
20. Sample Callout
public void SimpleCalloutToGoogle(string endpoint, string method, string body){
// set up the request
HttpRequest req = new HttpRequest();
req.setEndpoint(endpoint);
req.setMethod(method);
req.setTimeout(10000);
// set the headers and body
req.setHeader('Content-Type', 'text/xml; charset=UTF-8');
req.setHeader('SOAPAction', '');
// make the callout
Http h = new Http();
HttpResponse res = h.send(req);
// inspect results with XmsStreamReader...
}
