BUSINESS MESSAGES: ECHO BOT WITH MESSAGE VALIDATION

In addition to demonstrating how to receive a message from the Business Messages platform and echo the same message back to the user, this sample demonstrates how to validate messages are actually from Google using the Business Messages Node.js SDK. Using Google Cloud Platform Logger, you can view the logs and compare the x-goog-signature from the message payload to the locally generated signature.

You will need you partner key that you received at the time of registration.

The sample also supports the following commands:

  • card - The bot responds with a sample rich card
  • carousel - The bot responds with a sample carousel
  • chips - The bot responds with sample suggested replies

This runs on the Google App Engine.

See the Google App Engine (https://cloud.google.com/appengine/docs/nodejs/) standard environment documentation for more detailed instructions.

PREREQUISITES

You must have the following software installed on your development machine:

SETUP

Register with Business Messages:

1.  Open [Google Cloud Console](https://console.cloud.google.com) with your
    Business Messages Google account and create a new project for your agent.

    Note the **Project ID** and **Project number** values.

2.  Open the
    [Business Messages API](https://console.developers.google.com/apis/library/businessmessages.googleapis.com)
    in the API Library.

3.  Click **Enable**.

4.  [Register your project](https://developers.google.com/business-communications/business-messages/guides/set-up/register)
    with Business Messages.

Create a Business Messages agent:

*   Open the [Create an agent](https://developers.google.com/business-communications/business-messages/guides/set-up/agent)
    guide and follow the instructions to create a Business Messages agent.

RUN THE SAMPLE

1.  In a terminal, navigate to this sample's root directory.

2.  Update the partnerKey in ./src/main/java/com/google/businessmessages/samples/servlets/AgentCallback.java:123
    with the partnerKey you received with the confirmation email from
    registering with Business Messages

2.  Run the following commands:

    gcloud config set project PROJECT_ID

    Where PROJECT_ID is the project ID for the project you created when you registered for
    Business Messages

    mvn appengine:deploy

3.  On your mobile device, use the test business URL associated with the
    Business Messages agent you created. Open a conversation with your agent
    and type in "Hello". Once delivered, you should receive "Hello" back
    from the agent.

    Try entering "card", "carousel", and "chips" separately to explore other
    functionality.
