Respond to incidents with Google Chat, Vertex AI, and Apps Script

This tutorial shows how to make a Google Chat app that responds to incidents in real time. When responding to an incident, the app creates and populates a Chat space, facilitates incident resolution with messages, slash commands, and dialogs, and uses AI to summarize the incident response in a Google Docs document.

An incident is an event that requires the immediate attention of a team of people to resolve. Examples of incidents include:

  • A time-sensitive case is created in a Customer Relationship Management (CRM) platform, requiring a service team to collaborate on a resolution.
  • A system goes offline, alerting a group of site reliability engineers (SREs) so that they can work together to bring it back online.
  • A high magnitude earthquake occurs, and emergency workers need to coordinate their response.

For the purposes of this tutorial, the incident alert starts when someone reports the incident with a button click from a web page. The web page simulates an incident by asking users to enter basic incident information: title, description, and email addresses of the responders.

See the incident management Chat app in action:

  • The website that starts an incident.

Prerequisites

If you need any of these prerequisites turned on for your organization, ask your Google Workspace administrator to turn them on:

  • A Business or Enterprise Google Workspace account with access to Google Chat.
  • To have Directory (contact sharing) turned on for Google Workspace. The incident app uses the directory to look up the incident responders' contact info, like name and email address. Incident responders must be users with a Google Chat account in your Google Workspace organization.

Objectives

  • Build a Chat app that responds to incidents.
  • Help users respond to incidents by doing the following:
    • Creating incident response spaces.
    • Posting messages summarizing incidents and responses.
    • Supporting collaboration with interactive Chat app features.
  • Summarize conversations and resolutions with Vertex AI.

Architecture

The following diagram shows the architecture of the Google Workspace and Google Cloud resources used by the incident response Google Chat app.

Architecture of the incident response Google Chat app

The architecture shows how the incident response Google Chat app processes an incident and resolution.

  1. A user starts an incident from an external website hosted on Apps Script.

  2. The website sends an asynchronous HTTP request to the Google Chat app, also hosted on Apps Script.

  3. The incident response Google Chat app processes the request:

    1. The Apps Script Admin SDK service gets team member information, like user ID and email address.

    2. With a set of HTTP requests to Chat API using the Apps Script Advanced Chat service, the incident response Google Chat app creates an incident Chat space, populates it with team members, and sends a message to the space.

  4. Team members discuss the incident in the Chat space.

  5. A team member invokes a slash command to signal a resolution to the incident.

    1. An HTTP call to Chat API using the Apps Script Advanced Chat service lists all the Chat space's messages.

    2. Vertex AI receives the listed messages and generates a summary.

    3. The Apps Script DocumentApp service creates a Docs document and adds Vertex AI's summary to the document.

    4. The incident response Google Chat app calls Chat API to send a message sharing a link to the summary Docs document.

Prepare the environment

This section shows how to create and configure a Google Cloud project for the Chat app.

Create a Google Cloud project

Google Cloud console

  1. In the Google Cloud console, go to Menu > IAM & Admin > Create a Project.

    Go to Create a Project

  2. In the Project Name field, enter a descriptive name for your project.

    Optional: To edit the Project ID, click Edit. The project ID can't be changed after the project is created, so choose an ID that meets your needs for the lifetime of the project.

  3. In the Location field, click Browse to display potential locations for your project. Then, click Select.
  4. Click Create. The Google Cloud console navigates to the Dashboard page and your project is created within a few minutes.

gcloud CLI

In one of the following development environments, access the Google Cloud CLI (gcloud):

  • Cloud Shell: To use an online terminal with the gcloud CLI already set up, activate Cloud Shell.
    Activate Cloud Shell
  • Local Shell: To use a local development environment, install and initialize the gcloud CLI.
    To create a Cloud project, use the gcloud projects create command:
    gcloud projects create PROJECT_ID
    Replace PROJECT_ID by setting the ID for the project you want to create.

Enable billing for the Cloud project

Google Cloud console

  1. In the Google Cloud console, go to Billing. Click Menu > Billing > My Projects.

    Go to Billing for My Projects

  2. In Select an organization, choose the organization associated with your Google Cloud project.
  3. In the project row, open the Actions menu (), click Change billing, and choose the Cloud Billing account.
  4. Click Set account.

gcloud CLI

  1. To list available billing accounts, run:
    gcloud billing accounts list
  2. Link a billing account with a Google Cloud project:
    gcloud billing projects link PROJECT_ID --billing-account=BILLING_ACCOUNT_ID

    Replace the following:

    • PROJECT_ID is the Project ID for the Cloud project for which you want to enable billing.
    • BILLING_ACCOUNT_ID is the billing account ID to link with the Google Cloud project.

Enable the APIs

Google Cloud console

  1. In the Google Cloud console, enable the Google Chat API, the Google Docs API, the Admin SDK API, and the Vertex AI API.

    Enable the APIs

  2. Confirm that you're enabling the APIs in the correct Cloud project, then click Next.

  3. Confirm that you're enabling the correct APIs, then click Enable.

gcloud CLI

  1. If necessary, set the current Cloud project to the one you created with the gcloud config set project command:

    gcloud config set project PROJECT_ID

    Replace PROJECT_ID with the Project ID of the Cloud project you created.

  2. Enable the Google Chat API, Google Docs API, Admin SDK API, and Vertex AI API with the gcloud services enable command:

    gcloud services enable chat.googleapis.com docs.googleapis.com admin.googleapis.com aiplatform.googleapis.com

Set up authentication and authorization

Authentication and authorization lets the Chat app access resources in Google Workspace and Google Cloud to process an incident response.

In this tutorial, you publish the app internally so it's OK to use placeholder information. Before publishing the app externally, replace placeholder information with real information for the consent screen.

  1. In the Google Cloud console, go to Menu > APIs & Services > OAuth consent screen.

    Go to OAuth consent screen

  2. Under User type, select Internal, then click Create.

  3. In App name, type Incident Management.

  4. In User support email, select your email address or an appropriate Google group.

  5. Under Developer contact information, enter your email address.

  6. Click Save and Continue.

  7. Click Add or Remove Scopes. A panel appears with a list of scopes for each API that you've enabled in your Cloud project.

  8. Under Manually add scopes, paste the following scopes:

    • https://www.googleapis.com/auth/chat.spaces.create
    • https://www.googleapis.com/auth/chat.memberships
    • https://www.googleapis.com/auth/chat.memberships.app
    • https://www.googleapis.com/auth/chat.messages
    • https://www.googleapis.com/auth/documents
    • https://www.googleapis.com/auth/admin.directory.user.readonly
    • https://www.googleapis.com/auth/script.external_request
    • https://www.googleapis.com/auth/userinfo.email
    • https://www.googleapis.com/auth/cloud-platform
  9. Click Add to Table.

  10. Click Update.

  11. Click Save and Continue.

  12. Review the app registration summary, then click Back to Dashboard.

Create and deploy the Chat app

In the following section, you copy and update an entire Apps Script project that contains all the required application code for your Chat app, so there's no need to copy and paste each file.

Some functions include underscores at the end of their names, like processSlashCommand_() from ChatApp.gs. The underscore hides the function from the incident initialization web page when it's open in a browser. For more information, see Private functions.

Apps Script supports two file types, .gs scripts and .html files. To abide by this support, the app's client-side JavaScript is included inside <script /> tags and its CSS is included inside <style /> tags inside an HTML file.

Optionally, you can view the entire project on GitHub.

View on GitHub

Here's an overview of each file:

Consts.gs

Defines constants referenced by other code files, including your Cloud project ID, Vertex AI location ID, and the slash command ID for closing an incident.

View Consts.gs code

apps-script/incident-response/Consts.gs
const PROJECT_ID = 'replace-with-your-project-id';
const VERTEX_AI_LOCATION_ID = 'us-central1';
const CLOSE_INCIDENT_COMMAND_ID = 1;
ChatApp.gs

Handles Chat interaction events, including messages, card clicks, slash commands, and dialogs. Responds to the /closeIncident slash command by opening a dialog to gather incident resolution details. Reads messages in the space by calling the spaces.messages.list method in the Chat API. Gets user IDs using the Admin SDK Directory service in Apps Script.
