Google Books™ Custom Adapter for Salesforce Connect
This example illustrates how to work around the requirements and limits of an
external system’s APIs: in this case, the Google Books API Family.
To integrate with the Google Books™ service, we set up Salesforce Connect as follows.
- The Google Books API allows a maximum of 40 returned results, so we develop our custom adapter to handle result sets with more than 40 rows.
- The Google Books API can sort only by search relevance and publish dates, so we develop our custom adapter to disable sorting on columns.
- To support OAuth, we set up our authentication settings in Salesforce so that the requested scope of permissions for access tokens includes https://www.googleapis.com/auth/books.
- To allow Apex callouts, we define these remote sites in Salesforce:
- https://www.googleapis.com
- https://books.google.com
