**Configuration Parameters:**

* **BigQuery Project** \* - GCP project ID (e.g. `my-gcp-project`).
* **Service Account Key JSON** \* (sensitive) - Full JSON contents of a service-account key with the BigQuery roles you need.

**Setup Steps:**

1. In the Google Cloud Console, select the project that owns the BigQuery data.
2. Navigate to **IAM & Admin → Service Accounts → Create Service Account**, then grant `roles/bigquery.dataViewer` and `roles/bigquery.jobUser` (or a narrower set).
3. From the new account's **Keys** tab, click **Add Key → Create new key**, choose **JSON**, and download the file.
4. When creating the connection in Natoma, paste the JSON contents and the project ID, then save.
