Hi Thuc,
Thanks, understand and clear you like to use the both clouds.
Are you in contact with the team about the connector? believe they can share more info to setup Airvantage<>Google Cloud.

And in that case, WP only need to be able to upload data to Airvantage server, below the guideline for that part if you haven’t go thru.
