Manage pages with the API

In most cases, you will use the console to manage pages. In advanced scenarios, you may wish to use the API to manage pages. This guide describes how to create, list, and delete pages using the API.

Create page

To create a page for your agent, call the create method on the Page type.

Select a protocol and version for the Page reference:

Protocol V3 V3beta1
REST Page resource Page resource
RPC Page interface Page interface
C# Not available Not available
Go Not available Not available
Java PagesClient PagesClient
Node.js PagesClient PagesClient
PHP Not available Not available
Python PagesClient PagesClient
Ruby Not available Not available

import com.google.cloud.dialogflow.cx.v3.CreatePageRequest;
import com.google.cloud.dialogflow.cx.v3.Page;
import com.google.cloud.dialogflow.cx.v3.PagesClient;
import java.io.IOException;

public class CreateSimplePage {

  public static void main(String[] args) throws IOException {
    // TODO(developer): Replace these variables before running the sample.
    String projectId = "my-project-id";
    String agentId = "my-agent-id";
    String flowId = "my-flow-id";
    String location = "my-location";
    String displayName = "my-display-name";

    createPage(projectId, agentId, flowId, location, displayName);
  }

  // DialogFlow API Create Page Sample.
  // Creates a page from the provided parameters
  public static Page createPage(
      String projectId, String agentId, String flowId, String location, String displayName)
      throws IOException {
    Page response;
    CreatePageRequest.Builder createRequestBuilder = CreatePageRequest.newBuilder();
    Page.Builder pageBuilder = Page.newBuilder();

    pageBuilder.setDisplayName(displayName);

    createRequestBuilder
        .setParent(
            "projects/"
                + projectId
                + "/locations/"
                + location
                + "/agents/"
                + agentId
                + "/flows/"
                + flowId)
        .setPage(pageBuilder);

    // Make API request to create page
    try (PagesClient client = PagesClient.create()) {
      response = client.createPage(createRequestBuilder.build());
      System.out.println("Successfully created page!");
      return response;
    }
  }

Node.js

async function createPage(projectId, agentId, flowId, location, displayName) {
  const pagesClient = new PagesClient();

  const createPageRequest = {
    parent: `projects/${projectId}/locations/${location}/agents/${agentId}/flows/${flowId}`,
    page: {
      displayName: displayName,
    },
  };

  const response = await pagesClient.createPage(createPageRequest);
  console.log(response);
}

Python

async def create_page(project_id, agent_id, flow_id, location, displayName):
    pages_client = PagesAsyncClient()

    page = Page()
    page.display_name = displayName

    request = CreatePageRequest()
    request.parent = (
        "projects/"
        + project_id
        + "/locations/"
        + location
        + "/agents/"
        + agent_id
        + "/flows/"
        + flow_id
    )
    request.page = page

    response = await pages_client.create_page(request=request)
    return response

List pages

To list the pages for your agent, call the list method on the Page type.

Select a protocol and version for the Page reference:
