Setup a Google Chat service account

Service accounts are the primary way to interact with Google Cloud resources, and setting up a chatbot is no different.

The first step is to create a new Google Cloud project. Visit and fill the required fields:

Then, visit this page to enable the Google Chat API for this project:

Then, go to Identity > Service Accounts in the menu (or visit and create a service account for the project.

Once the service account is created, you will need to generate a key. Select the service account, click on Add Key > Create New Key, select JSON as the Key type, and save the file.

Setup the channel in CSML Studio

In CSML Studio, under Channels > Connect a new channel, select the Google Chat channel. In the next screen, give your channel a name, a description and upload your service account credentials.

In the next screen, you can configure the bot's Welcome Flow, and copy the Chatbot Endpoint URL, which we will use in the next step.

Connect the chatbot with Google Chat

To finalize the configuration, visit (make sure that the selected project is still the same one as before) and fill the information as requested.

You can select Bot works in direct messages or Bot works in rooms... depending on the experience you want to give to users.

Under Bot URL, paste the Chatbot Endpoint URL from the previous step.

Click Save, and you are all set!
