OAuth Service Account Flow

This guide will walk you through how to setup OAuth2 for API access using your own credentials using service accounts. These steps only need to be done once, unless you revoke or delete your OAuth2 credentials.

Step 1 - Creating OAuth2 credentials

Generate a service account ID and a *.JSON file by following the linked instructions, then come back to this page.

Step 2 - Setting up the client library using JSON configuration file

Configure the following keys in your App.config / Web.config. See the configuration guide for additional details.

<add key="OAuth2Mode" value="SERVICE_ACCOUNT" />
<add key="OAuth2SecretsJsonPath" value="INSERT_OAUTH2_SECRETS_JSON_FILE_PATH_HERE" />

<!-- Supply the email address of the user to impersonate. -->
<add key="OAuth2PrnEmail" value="INSERT_OAUTH2_USER_EMAIL_HERE" />
