Deploy the SAM Template:

Deploy your SAM template to AWS and retrieve the API endpoint from the CloudFormation stack output.

Check Feature Flag Status:

Hit the API endpoint with the “/config” URL to view the current status of the feature flags.

Toggle Feature Flags:

Navigate to AppConfig in the AWS Console, locate the feature flags, and toggle them as needed.

Save and Deploy Changes:

Save your changes and start the deployment of a new AppConfig version.

Confirm Deployment:

On the deployment page, confirm the environment, version, and deployment strategy, then hit deploy.

Verify Deployment:

Ensure the deployment is successful.

Re-check Feature Flag Status:

Hit the API endpoint again with the “/config” URL to verify the updated status of the feature flags.
