  • Developer
IMPORTANT
The Google BigQuery source is available in the sources catalog to users who have purchased Real-Time Customer Data Platform Ultimate.

A base connection represents the authenticated connection between a source and ÃÛ¶¹ÊÓƵ Experience Platform.

Read this guide to learn how to create a base connection for Google BigQuery using the .

Get started

This guide requires a working understanding of the following components of 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 Google BigQuery using the Flow Service API.

Gather required credentials

Read the Google BigQuery authentication guide for detailed steps on gathering your required credentials.

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 Google BigQuery authentication credentials as part of the request parameters.

API format

POST /connections
Use basic authentication

Request

The following request creates a base connection for Google BigQuery using basic authentication:

code language-shell 
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: {ORG_ID}' \
    -H 'x-sandbox-name: {SANDBOX_NAME}' \
    -H 'Content-Type: application/json' \
    -d '{
        "name": "Google BigQuery connection with basic authentication",
        "description": "Google BigQuery connection with basic authentication",
        "auth": {
            "specName": "Basic Authentication",
            "type": "OAuth2.0",
            "params": {

                }
        },
        "connectionSpec": {
            "id": "3c9b37f8-13a6-43d8-bad3-b863b941fedd",
            "version": "1.0"
        }
    }'
table 0-row-2 1-row-2 2-row-2 3-row-2 4-row-2 5-row-2
Property Description
auth.params.project The project ID of the default Google 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 Google 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.

    -H 'x-sandbox-name: {SANDBOX_NAME}' \
    -H 'Content-Type: application/json' \
    -d '{
        "name": "Google BigQuery base connection with service account",
        "description": "Google BigQuery connection with service account",
        "auth": {
            "specName": "Service Authentication",
            "params": {
                    "projectId": "{PROJECT_ID}",
