cfnresponse

cfnresponse is a micro Python package designed to simplify sending responses from AWS Lambda functions acting as custom resources back to AWS CloudFormation. It abstracts the HTTP call to the pre-signed S3 URL provided by CloudFormation, ensuring that stack operations (create, update, delete) complete successfully or fail gracefully. The current version is 1.1.5, and releases are infrequent, primarily for updates related to AWS Lambda runtime environments or underlying HTTP client changes.
