A Pulumi example that:

• Creates an AWS Lambda function to post a message on Slack via a Webhook URL.
• Adds an AWS API Gateway so the Lambda can be invoked externally, e.g, via GitHub Webhooks.
• Uses a Pulumi ESC Environment to dynamically retrieve AWS OIDC Credentials and the Slack URL from AWS Secrets Manager.
