Connecting to Google BigQuery Using OAuth Authentication

[animesh123]

 We are following the process below to create a service account token for connecting to GCP Big query.

Created an Azure client id and client secret.
Generated an Azure Access Token using ClientID, client secret, and GCP project number.
Created a Workload Identity Token using GCP project number and Azure Token.
Generated a Service Account Token using service account name and workload identity token.

We have updated the SAS code to connect to GCP Big query using GCP project ID and Service Account Token as a refresh token, and the project Id as the Client ID.

We are unsure about the correct value to use for the client secret. Could you please guide us on how to establish a connection using the Service Account Token generated from the WIF process.

%let WIF_TOKEN = %sysget(WIF_TOKEN);
