requests-aws-sign
This package provides AWS V4 request signing using the requests library.
Decision gist · record as of 2026-08-14
No. The package is abandoned (last commit 2020-07-05) and targets Python versions that are now end-of-life. While it has low install friction and a permissive license, its compatibility with modern Python and current boto3/requests versions is unverified. For new projects, use boto3's built-in clients; for existing requests-based code, consider migrating or forking if you need to maintain it.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires valid AWS credentials available to boto3 (environment variables, IAM role, or profile configuration) and a specified AWS region.
- Installation is straightforward with low friction.
- However, the package is abandoned—last release was 2020-07-05 and no commits since then.

What it is and what it does
requests-aws-sign is a thin wrapper that plugs AWS V4 request signing into the requests library's authentication system. It takes a boto3 credentials object, an AWS region, and a service name, then returns an auth handler that automatically signs outgoing HTTP requests with the required AWS headers (X-Amz-Date, X-Amz-Security-Token, Authorization). This lets you make authenticated calls to AWS services like Elasticsearch, API Gateway, or any other service that accepts IAM-signed requests.
The package depends on requests and boto3. It is designed to work with boto3's credential chain, so it can use environment variables, assume-role profiles, or EC2 instance IAM roles. However, the package has been abandoned since 2020-07-05 and was originally written for Python 2.6–3.5, raising questions about compatibility with modern Python and current AWS SDK versions.
Use it for
- Sign requests to AWS Elasticsearch domains that require IAM authentication instead of basic auth.
- Authenticate direct HTTP calls to API Gateway endpoints protected by IAM policies.
- Build custom AWS service clients using requests when the official boto3 client is not suitable.
- Integrate AWS request signing into existing requests-based HTTP workflows without rewriting to boto3.
