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
- 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) { } }
- 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.
