Why integrating BigQuery was a challenge? BigQuery requires authentication and authorization of the data submitted using the client libraries supported by BigQuery API, which are C#, GO, Java, Node.js, PHP, Python, and Ruby. Engaging Networks used in the Acespace project allows us to edit HTML, CSS, and JavaScript only. Thus BigQuery API integration was not possible there could be many security issues. Hence, we found a PHP-based solution in which we first submitted the data to AirTable and then integrated AirTable into BigQuery using external PHP code. The PHP script reads from AirTable in a row-wise manner. Then inserts the same row into BigQuery, and delete it from AirTable. Furthermore, we scheduled this PHP script to run every few hours using a Cron job.

For this PHP implementation service, an account and API were created in Google Console.

Your service account J-SON will be downloaded to your computer, which contains the details of the service account created and the key generated will also be provided in the downloaded file. Keep the file safe as you will need this later.
The newly created Service Account will be listed in the Service Account menu selected from the IAM & Admin navigation panel.
