## Getting Started with Big Query

There are three steps to connect Big Query with Secoda:

1. Enable the Big Query API
2. Create a service account for Secoda
3. Connect Big Query to Secoda

#### Enable Big Query API for GCP <a href="#h_3ec8fd603e" id="h_3ec8fd603e"></a>

Log in to your existing project on GCP and [enable the BigQuery API](https://cloud.google.com/bigquery/docs/quickstarts/quickstart-web-ui). Once you’ve done so, you should see BigQuery in the [“Resources” section](https://cl.ly/0W2i2I2B2R0M) of Cloud Platform.

#### Create a service account for Secoda <a href="#h_f7ed2acb85" id="h_f7ed2acb85"></a>

To provide [least privilege](https://en.wikipedia.org/wiki/Principle_of_least_privilege) to Secoda for extracting Big Query metadata, you can create a new service account following the steps below. Refer to [Google Cloud’s documentation about service accounts](https://cloud.google.com/iam/docs/creating-managing-service-accounts) for more information.

1. From the Navigation panel on the left, go to **IAM & admin** > **Service accounts**
2. Click **Create Service Account** along the top
3. Enter a name (for example: “secoda”) and click **Create**
4. When assigning permissions, make sure to grant the following permissions:

a) If you're creating the service account via the GCP console add the following roles:

```
BigQuery Metadata Viewer
BigQuery Resource Viewer
BigQuery Data Viewer
BigQuery Job User
```

If you want to enable metadata push feature, add the following role:

```
BigQuery Data Editor
```

If you want to enable syncing policy tags, add the following roles:

```
Data Catalog Admin
Data Catalog Tag Editor
Tag User
```

b) If you're programatically creating the service account add the following roles:

```
roles/bigquery.metadataViewer
roles/bigquery.resourceViewer
roles/bigquery.dataViewer        
roles/bigquery.jobUser
```

If you want to enable metadata push feature, add the following role:

```
roles/bigquery.tables.update
```

If you want to enable syncing policy tags, add the following roles:

```
roles/datacatalog.admin
roles/datacatalog.tagEditor
roles/datacatalog.tagUser
```

5\. [Create a JSON key](https://cloud.google.com/iam/docs/creating-managing-service-account-keys). The downloaded file will be used to create your warehouse in the next section.

#### Connect Big Query to Secoda <a href="#h_724f251572" id="h_724f251572"></a>

* Log into your Secoda profile at <https://app.secoda.co>
* From the Navigation panel on the left go **Integrations** > **Add new integration**
* Select **Big Query**
* Enter in the project name and paste the JSON key file contents that was downloaded
* Click "Connect"
