Publish to SNS

The Publish action sends a message to all of a topic’s subscribed endpoints. A returned messageId indicates that the message was saved and Amazon SNS will attempt to deliver it to the topic’s subscribers shortly. The format of the outgoing message to each subscribed endpoint depends on the notification protocol selected. Lets see how we can publish to SNS

Create project in Anypoint studio and configure the listener to trigger the flow

Drag and drop publish operation and provide the connector configuration

Topic ARN: The topic you want to publish to.

To get the topic arn you can get the arn value from Amazon SNS Service as shown below

Message:The message you want to send to the topic.

Subject:Optional parameter to use as the “Subject” line when the message is delivered to email endpoints

Create the transform message to send the message to subscribed endpoint as a string value

%dw 2.0
output application/json
---
'{
    "EmployeeId":1234,
    "EmployeeName":"John",
    "EmployeeEmail":"Dey"
}'

See below url to check when we need to send the string message and when as a json object
