Create a Google BigQuery base connection using the Flow Service API

NOTE

The Google BigQuery connector is in beta. See the Sources overview for more information on using beta-labelled connectors.

A base connection represents the authenticated connection between a source and Adobe Experience Platform.

This tutorial walks you through the steps to create a base connection for Google BigQuery (hereinafter referred to as “BigQuery”) using the Flow Service API.

Getting started

This guide requires a working understanding of the following components of Adobe Experience Platform:

  • Sources: Experience Platform allows data to be ingested from various sources while providing you with the ability to structure, label, and enhance incoming data using Platform services.
  • Sandboxes: Experience Platform provides virtual sandboxes which partition a single Platform instance into separate virtual environments to help develop and evolve digital experience applications.

The following sections provide additional information that you will need to know in order to successfully connect to BigQuery using the Flow Service API.

Gather required credentials

In order for Flow Service to connect BigQuery to Platform, you must provide the following OAuth 2.0 authentication values:

Credential Description
project The project ID of the default BigQuery project to query against.
clientID The ID value used to generate the refresh token.
clientSecret The secret value used to generate the refresh token.
refreshToken The refresh token obtained from Google used to authorize access to BigQuery.
connectionSpec.id The connection specification returns a source’s connector properties, including authentication specifications related to creating the base and source connections. The connection specification ID for BigQuery is: 3c9b37f8-13a6-43d8-bad3-b863b941fedd.

For more information about these values, refer to this BigQuery document.

Using Platform APIs

For information on how to successfully make calls to Platform APIs, see the guide on getting started with Platform APIs.

Create a base connection

A base connection retains information between your source and Platform, including your source’s authentication credentials, the current state of the connection, and your unique base connection ID. The base connection ID allows you to explore and navigate files from within your source and identify the specific items that you want to ingest, including information regarding their data types and formats.

To create a base connection ID, make a POST request to the /connections endpoint while providing your BigQuery authentication credentials as part of the request parameters.

API format

POST /connections

Request

The following request creates a base connection for BigQuery:

curl -X POST \
    'https://platform.adobe.io/data/foundation/flowservice/connections' \
    -H 'Authorization: Bearer {ACCESS_TOKEN}' \
    -H 'x-api-key: {API_KEY}' \
    -H 'x-gw-ims-org-id: {IMS_ORG}' \
    -H 'x-sandbox-name: {SANDBOX_NAME}' \
    -H 'Content-Type: application/json' \
    -d '{
        "name": "Google BigQuery connection",
        "description": "Google BigQuery connection",
        "auth": {
            "specName": "Basic Authentication",
            "type": "OAuth2.0",
            "params": {
                    "project": "{PROJECT}",
                    "clientId": "{CLIENT_ID},
                    "clientSecret": "{CLIENT_SECRET}",
                    "refreshToken": "{REFRESH_TOKEN}"
                }
        },
        "connectionSpec": {
            "id": "3c9b37f8-13a6-43d8-bad3-b863b941fedd",
            "version": "1.0"
        }
    }'
Property Description
auth.params.project The project ID of the default BigQuery project to query. against.
auth.params.clientId The ID value used to generate the refresh token.
auth.params.clientSecret The client value used to generate the refresh token.
auth.params.refreshToken The refresh token obtained from Google used to authorize access to BigQuery.
connectionSpec.id The Google BigQuery connection specification ID: 3c9b37f8-13a6-43d8-bad3-b863b941fedd.

Response

A successful response returns details of the newly created connection, including its unique identifier (id). This ID is required to explore your data in the next tutorial.

{
    "id": "6990abad-977d-41b9-a85d-17ea8cf1c0e4",
    "etag": "\"ca00acbf-0000-0200-0000-60149e1e0000\""
}

Next steps

By following this tutorial, you have created a BigQuery connection using the Flow Service API, and have obtained the connection’s unique ID value. You can use this connection ID in the next tutorial as you learn how to explore databases or NoSQL systems using the Flow Service API.
