ballerinax/trigger.salesforce Ballerina library

Overview

The ballerinax/trigger.salesforce module provides a Listener to grasp events triggered from a Salesforce org. This functionality is provided by Salesforce Streaming API.

Prerequisites

Before using this connector in your Ballerina application, complete the following:

• Create a Salesforce account.
• Obtain the security token for the your Salesforce org by visiting
  Profile -> Settings -> My Personal Information -> Reset My Security Token
• Add the API Enabled permission & Streaming API permissions for your Salesforce org.
• Prerequisites for different kind of events
  • Subscribe to Change Data Capture Events
    1. Subscribe to channels to receive notifications for record changes by visiting
       Setup -> Integrations -> Change Data Capture

Quickstart

To use the Salesforce listener in your Ballerina application, update the .bal file as follows:

Step 1: Import listener

Import the ballerinax/trigger.salesforce as sfdc module as shown below.

import ballerinax/trigger.salesforce as sfdc;

Step 2: Create a new listener instance

Create a sfdc:Listener using your Salesforce User Name, Salesforce Password Salesforce Security Token, Subscribe Channel Name and initialize the listener with it.

sfdc:ListenerConfig configuration = {
    username: "USER_NAME",
    password: "PASSWORD_SECURITY_TOKEN",
    channelName: "CHANNEL_NAME"
};
listener Listener sfdcListener = new (configuration);

Step 3: Implement a listener remote function

1. Now you can implement a listener remote function supported by this connector.

• Write a remote function to receive a particular event type. Implement your logic within that function as shown in the below sample.

• Following is a simple sample for using Salesforce listener

import ballerina/log;
import ballerinax/trigger.salesforce as sfdc;

service sfdc:StreamingEventService on sfdcListener {
    isolated remote function onUpdate(sfdc:EventData event) returns error? {
        log:printInfo(event.toString());
    }

    isolated remote function onCreate(sfdc:EventData event) {

    }
        
    isolated remote function onDelete(sfdc:EventData event) {

    }

    isolated remote function onRestore(sfdc:EventData event) {

    }
}

2. Use bal run command to compile and run the Ballerina program.

• Receiving events
  • After successful verification of Request URL your ballerina service will receive events.
