# Integrating with BigQuery

[Prerequisites](#prerequisites)

[BigQuery Setup](#bigquery-setup)\
    [Add an external user in BigQuery](#add-an-external-user-in-bigquery)

## Prerequisites

To connect BigQuery to Drivetrain, you need:

* An active BigQuery account
* Sharing privileges on BigQuery
* Admin privileges in Drivetrain

## BigQuery Setup <a href="#bigquery-setup" id="bigquery-setup"></a>

Drivetrain supports integration with BigQuery from a read-only external user account. To get started you would need to share the read-only access with <drivetrain@integrations-417606.iam.gserviceaccount.com> service account.

1. Select the **Dataset/ Resource** which is to be shared with the user.
2. From the **Sharing** option on the right top of the page, route to **Permissions**.
3. Add <drivetrain@integrations-417606.iam.gserviceaccount.com> as principal.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://integrations.drivetrain.ai/integration-guide/integrate-with-drivetrain/databases-and-warehouses/integrating-with-bigquery.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
