The Perl client library is hosted onGitHub, and the package is
available onCPAN.
The library supports Perl version 5.28.1 or greater. To use this library, first
complete theprerequisites.
REST API protocol
Class entities—such as service, resource, enum, and error—in the
Perl client library are generated by parsing theprotocol buffer
definitions.
To learn more about how structured data is serialized, refer to theprotocol
buffer documentation.
To connect with the Google Ads API, the client library creates an HTTP request inJSON, sends it to the REST endpoint over HTTP
1.1, deserializes the response as a JSON object, and interprets the results.
