The Looker API offers two different ways to make use of an SDK. We suggest using one of our SDKs, instead of making manual requests to the API, because the SDKs already take care of the intricate details of authentication, parameter serialization, response serialization, and other concerns.
Option 1: Ruby SDK
Option 2: Swagger Generated SDK
If you are not familiar with Ruby or your company uses another language, you can generate a client SDK in the language of your choice. Instructions for doing so can be found in this Discourse article.
Documentation about our old Ruby SDK can be found here.
