Create integration with a Salesforce trigger

Learn how to create a sample integration in Application Integration using the Salesforce trigger. The following steps describe how to configure the trigger, tasks, connectors, and data mappings required to run a complete integration.

In this quickstart, you will use the Salesforce trigger to invoke an integration in Application Integration for a Salesforce Change Data Capture (CDC) event as shown in the following figure:

Sample sequence diagram Sample sequence diagram

A Salesforce trigger is subscribed to the Salesforce opportunity channel. Data changes to the Salesforce opportunity invokes an Application Integration which extracts the status of the Salesforce opportunity. If the status is closed, the integration extracts the opportunity details and writes the data to a Cloud SQL instance using a connector. If there is a data change, but the status remains open, the integration sends a message to a pub/sub topic using a connector.

The following steps describe how to configure the trigger, tasks, authentication profiles, edges, variables, and data mapping required to run a successful integration.

Before you begin

  • Confirm that your Salesforce developer account has Change Data Capture (CDC) enabled. This tutorial assumes that you have an existing Salesforce developer account with the required user setup and permission set. For information about Salesforce user setup and permission set, see Configure a Salesforce trigger.
  • Assign the following IAM roles to the Application Integration Service Agent(service-PROJECT_NUMBER@gcp-sa-integrations.iam.gserviceaccount.com) in your Google Cloud project.
    • Pub/Sub Editor
    • Connectors Admin
    • Application Integration Invoker
    For more information about assigning IAM roles, see IAM roles and permissions.
  • Create the Cloud SQL table to store the Salesforce CDC data.
    1. In the Google Cloud console, go to the Cloud SQL Instances page and connect to your MySQL instance. See Connect to Cloud SQL for MySQL from Cloud Shell.

      Go to Cloud SQL instances

    2. Create the following MySQL database on your Cloud SQL instance:
      CREATE DATABASE SALESFORCE_TRIGGER_DEMO;
      USE SALESFORCE_TRIGGER_DEMO;
      
      CREATE TABLE OPPORTUNITIES
      (
           ID              INT NOT NULL AUTO_INCREMENT,
           NAME            VARCHAR(150) NOT NULL,
           AMOUNT          DOUBLE NOT NULL,
           DT_CLOSE        VARCHAR(150) NOT NULL,
           PRIMARY KEY     (ID)
      );
      COMMIT;
      
    3. Verify that the table is created by executing the following command.
      SELECT * FROM OPPORTUNITIES;
  • Create a Cloud SQL for MySQL connection in Connectors. See Create a Cloud SQL for MySQL connection for detailed information.
  • Create a Cloud Pub/Sub connection in Connectors. See Create a Cloud Pub/Sub connection for detailed information.

Add and configure tasks

This tutorial uses the Connectors and Data Mapping tasks. Configuration details for each of these tasks are described as follows.

Configure a Connectors task with a Cloud SQL for MySQL connection

Perform the following steps to configure a Connectors task to insert records into an existing Cloud SQL table using the Cloud SQL for MySQL connection:

  1. Select +Add a task/trigger > Tasks in the integration designer to display the list of available tasks.
  2. Click and place the Connectors element in the integration designer.
  3. Click the Connectors task element on the designer to view the Connectors task configuration pane.
  4. Click and change the Connectors name as Insert row to Cloud SQL.
  5. Click Configure task.

    The Configure connector task dialog appears.

  6. Do the following in the Configure connector task dialog:

    2. Once a region is chosen, the Connection column appears. Select your Cloud SQL for MySQL connection from the list of available connections.
    3. Once a connection is chosen, the Type column appears. Select Entities and then OPPORTUNITIES from the list of available entities.
    4. Once a type is chosen, the Operation column appears. Select Create.
    5. Click Done to complete the connection configuration and close the pane.

Configure a Connectors task with a Cloud Pub/Sub connection

Perform the following steps to configure a Connectors task to publish a Pub/Sub message using the Cloud Pub/Sub connection:

  7. Once your mapping is complete, close the pane. Any changes will be autosaved.

Add edge connection

An edge is a connection between any two elements in an integration and an edge condition lets you specify the conditions that must be met for control of an integration to pass to the task connected by the edge. For more information on edges and edge conditions, see Edges.

  1. Add an edge connection from the Salesforce trigger element to the Data Mapping element.
  2. Add an edge connection from the Data Mapping element to the Insert row to Cloud SQL Connector element with the following edge condition:
      $OpportunityIsClosed$ = TRUE
  3. Add another edge connection from the Data Mapping element to the Cloud Pub/Sub Connector element with the following edge condition:
      $OpportunityIsClosed$ = FALSE

Test the integration

To test the new integration:

  1. Click Test in the integration designer toolbar, and then select the Salesforce Trigger.
  2. In the Confirm Publish and Test dialog, click Publish & Test.

Test the Cloud SQL task by logging in to the Salesforce instance and changing an opportunity status to "closed."

To verify the success of your integration:

  • Go to the Cloud SQL page.

    Go to Cloud SQL

    Check your database and Cloud SQL logs to confirm the insertion of the new row.
  • Go to the Pub/Sub page.

    Go to Pub/Sub

    Select your Pub/Sub topic and then click View messages to confirm receipt of the message sent by the integration.
  • Inspect the Application Integration logs to view the status of a given integration. To view logs:
