GENAI084

Overview

In this lab, you will enhance your Gemini Enterprise assistant by enabling it to handle employee business travel requests. The assistant will communicate with a conversational agent that processes these requests. To facilitate this, you will integrate an OpenAPI Tool, allowing the conversational agent to interact with a Cloud Run function. This function will then write the travel requests directly to BigQuery for storage and further processing. This diagram shows the flow you will enable:

Note: Using an Incognito browser window is recommended for most Qwiklabs to avoid confusion between multiple Qwiklabs student and other accounts. It is particularly helpful for Qwiklabs like this one that use the Conversational agents console. If you are using Chrome, the easiest way to accomplish this is to close any Incognito windows, then right click on the Open Google Cloud console button at the top of this lab and select Open link in Incognito window.

Objectives

In this lab, you learn how to:

• Deploy a Cloud Run function.
• Create an OpenAPI Tool for conversational agents to be able to call your Cloud Run function.
• Deploy a Gemini Enterprise app.
• Create a simple generative conversational agent using a Playbook.
• Integrate your conversational agent into your Gemini Enterprise app.

Setup and requirements

Before you click the Start Lab button

Read these instructions. Labs are timed and you cannot pause them. The timer, which starts when you click Start Lab, shows how long Google Cloud resources will be made available to you.

This Qwiklabs hands-on lab lets you do the lab activities yourself in a real cloud environment, not in a simulation or demo environment. It does so by giving you new, temporary credentials that you use to sign in and access Google Cloud for the duration of the lab.

What you need

To complete this lab, you need:

• Access to a standard internet browser (Chrome browser recommended).
• Time to complete the lab.

Note: If you already have your own personal Google Cloud account or project, do not use it for this lab.

Note: If you are using a Pixelbook, open an Incognito window to run this lab.

Task 1. Create a BigQuery table where travel requests can be recorded

In this task, you'll create a table to serve as the destination to store incoming travel requests that will be sent to the Gemini Enterprise assistant.

1. Open a Cloud Shell terminal, by pressing the G key followed by the S key on your keyboard.

2. Click the Authorize button when prompted to authorize Cloud Shell.

3. In your Cloud Shell terminal, paste the following to create a travel_requests_schema.json file to define the schema for a BigQuery table which will be used to record travel requests:

   cat > travel_requests_schema.json << EOF [ { "name": "user", "type": "STRING", "mode": "REQUIRED" }, { "name": "travel_purpose", "type": "STRING", "mode": "REQUIRED" }, { "name": "departure_city", "type": "STRING", "mode": "NULLABLE" }, { "name": "destination_city", "type": "STRING", "mode": "NULLABLE" }, { "name": "departure_date", "type": "STRING", "mode": "NULLABLE" }, { "name": "return_date", "type": "STRING", "mode": "NULLABLE" } ] EOF

4. Run the following commands in Cloud Shell to create the BigQuery dataset and table , using the schema defined in the travel_requests_schema.json file:

   bq --location=US mk -d {{{project_0.startup_script.bq_dataset | Bigquery Dataset}}} bq mk -t {{{project_0.startup_script.bq_dataset | Bigquery Dataset}}}.{{{project_0.startup_script.bq_table | Bigquery Table}}} travel_requests_schema.json

5. Once the dataset and table have been successfully created, you can close the Cloud Shell panel by clicking the X in the upper right of the terminal panel.

14. Click the Save button at the top of the Settings pane to save your changes.

    

15. Before you create a Playbook, you will create a Tool that the playbook can use to call the Cloud Run function you created. From the left-hand navigation menu, select Tools.

    

16. Click + Create.

17. For Tool name enter Record Travel Request.

18. Keep the Type set to OpenAPI.

19. For a Description, enter Used to record a travel request.

20. For Schema, keep the type YAML selected, and paste the following into the text box. This OpenAPI spec describes an API with:

    • A server url set to your Cloud Functions domain

    • A path called / that accepts POST requests that include JSON in a schema called TravelRequest

    • A definition of that TravelRequest schema to include the fields you defined in your BigQuery schema at the start of this lab:

      openapi: 3.0.0 info: title: Travel Requests API version: 1.0.0 servers: - url: 'YOUR_CLOUD_RUN_FUNCTION_URL' paths: /: post: summary: Record a new travel request operationId: recordTravelRequest requestBody: description: Travel request to add required: true content: application/json: schema: $ref: '#/components/schemas/TravelRequest' responses: '200': description: Success content: application/json: schema: type: object properties: message: type: string example: "New row has been added." components: schemas: TravelRequest: type: object required: - user - travel_purpose properties: user: type: string travel_purpose: type: string departure_city: type: string destination_city: type: string departure_date: type: string return_date: type: string

21. Replace YOUR_CLOUD_RUN_FUNCTION_URL in the spec above with your Cloud Run function's URL that you copied earlier.

22. Click Save at the top of the Tools pane.

23. To allow the Tool to invoke the Cloud Run function, switch to your browser tab displaying the Cloud Console (not the Conversational Agents console) and use the search bar at the top of the console to navigate to IAM.

24. Check the checkbox to Include Google-provided role grants.

25. Find the row for the Dialogflow Service Agent (you may need to refresh the page) and click the pencil edit icon on its row.

26. Click + Add another role.

27. In the Select a role field, enter Cloud Run Invoker.

28. Click Save.

    Click Check my progress to verify the objectives. Create a Conversational Agent tool to call the Cloud Run function

Task 4. Create a Conversational Agent Playbook

In this task, you'll create the conversational agent that can receive requests in natural language and use the Tool to write them to the BigQuery table via the Cloud Run function.

1. In the browser tab with the Conversational Agents console, use the left-hand navigation menu to select Playbooks.

2. Select the Default Generative Playbook that has already been created.

3. Change the Playbook name to Confirm Travel Data.

4. For a Goal, enter: Help users book travel.

5. For Instructions, paste the following into the text field:

   - Ask the user to provide for user name, travel purpose, departure city, destination city, and a range of dates. Assume a year of 2025 for dates without a year: - Use ${TOOL:Record Travel Request} - Let the user know that they should receive a list of flights to choose from in their email within 24 hours.

6. These Playbook instructions are designed for use by Gemini Enterprise because it only includes one turn of conversation, even though it does multiple things within that turn (invokes its tool and generates a response). Later, you will give the Gemini Enterprise agent the responsibility for gathering the relevant info before invoking this Playbook.

7. Click Save at the top of the Playbook pane.

8. In the upper right of the Conversational Agents console, click the Toggle simulator chat button () to preview the conversational agent.

9. In the Enter text input box at the bottom of this panel, start the chat with Can you help me book a flight?

10. Provide a name, travel purpose, departure city, destination city, and a date range (for example, Joe Smith. Customer Presentation. Berlin to Valencia. Feb 21 to 28.) to observe how the agent behaves.

11. You should see a card indicating that the Record Travel Request Tool was used, and you can click on it to see the Tool input and response:

    

    Note: Change the model in case of output other than 200 and restart the chat by resetting the conversation ().

12. Your chat should end with a statement similar to:

    

    Click Check my progress to verify the objectives. Create a Conversational Agent playbook

Task 5. Create a BigQuery Data Store
