Self-host Google Chat.
Create your own Google Chat app and connect it securely to Just Arrived.
Updated 21 September 2026
Use this option when your organisation cannot install the standard Just Arrived Marketplace app. Your Google Workspace administrator creates a Chat app in your own Google Cloud project and connects it to Just Arrived.
Set it up
Choose a self-hosted Chat app
If your organisation cannot install the Marketplace app, ask your Google Workspace administrator to create a Chat app in your own Google Cloud project. When it is ready, open Just Arrived → Connections → Google Chat → Advanced credentials.

Create and configure the Google Cloud project
In Google Cloud Console, create a project, enable the Google Chat API, and configure a Chat app that accepts direct messages and can join spaces. Set its HTTP endpoint to https://justarrived.io/api/public/gchat/events.

Create a service account key
In the same Google Cloud project, create a service account and download a JSON key. Your Google Cloud administrator may need to allow service-account key creation for the project.

Save and verify the Chat credentials
In Just Arrived → Connections → Google Chat → Advanced credentials, enter the Google Cloud project number and upload or paste the service-account JSON. Save it, send help to the Chat app in Google Chat, and then test a kiosk arrival.
