AWS EventBridge triggered functions

Official Content

Amazon EventBridge is a serverless event bus service that delivers a stream of real-time data from your applications to AWS Lambda functions.

When you configure the Trigger type property of a Deployment Unit object to "Event Bridge," triggers will respond to messages from the event bus service.

Deployment steps

First, read How to: create a GeneXus procedure to be deployed as an Azure Function or an AWS Lambda Function.

To deploy the function, use the deployment tool. See Deploy to AWS Lambda Function.

Properties Configuration

In the Deployment Unit, set the following properties as shown below:

  1. AWS Access Key ID/AWS Secret Access Key: Enter your AWS Access Key.
  2. AWS Default Region: Select your preferred region (localization) for your Deployment.
  3. Function Name: It's the name used to display the application.
  4. Trigger type: Select EventBridge.
  5. IAM Execution Role ARN property: Enter the Amazon Resource Names (ARNs) path.
