Invoke an integration for a Salesforce Change Data Capture (CDC) event

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:

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([e-mail]) 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.
