Getting Started

• Copy at minimum the configration_sample.yml and lookerapi.py files.
• Change the config_sample.yml to config.yml and update with your credentials. You can get API 3 credentials by:
  1. Go to Admin > Users in your Looker instance.
  2. Either make a new user or click to an existing users page using the "Edit" button. Remember the API user will have the same credentials as the user so keep that security point in mind when choosing a user.
  3. Click the "New API 3 Key" button to make API 3 credentials for the user.
  4. In the config.yml file, the "Client Secret" on the user page should be copied into the secret: string and the Client ID should be copied into the token: string. For the host: string replace the word localhost with your Looker instance domain name (i.e. companyname.looker.com).
  5. Make sure your Looker instance is configured to a working API Host URL by going to Admin > API in your Looker instance and checking the API Host URL field. A blank field is the default for Looker to auto-detect the API Host URL.
• Run any file in the shell with python <<filename>>
