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
