# requests-auth-aws-sigv4 — AWS SigV4 Authentication with the python requests module

License: permissive · Maintenance: dormant · Downloads: 3.5M/mo

## What it is and what it does

This package provides an authentication handler for the requests library that automatically signs HTTP requests with AWS Signature Version 4, the standard authentication method for AWS APIs. It wraps the signing logic and integrates seamlessly with requests' auth parameter, allowing you to make authenticated calls to any AWS service—including API Gateway, Elasticsearch, STS, EC2, and others—without manually constructing signatures.

The package supports multiple credential sources: it will automatically use boto3-configured credentials (AWS CLI or SDK settings) if available, fall back to environment variables (AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, AWS_SESSION_TOKEN), or accept credentials passed directly as parameters. It also includes a command-line interface for curl-like usage and supports temporary security credentials from AWS STS.

Use it for:

- Make authenticated requests to AWS API Gateway endpoints from Python without managing signature headers manually.
- Query AWS services like EC2, STS, or Elasticsearch from a Python application using standard requests syntax.
- Integrate AWS API calls into libraries that use requests under the hood.
- Build CLI tools or scripts that need to call AWS APIs with credentials from environment or boto3 configuration.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Adds AWS Signature Version 4 authentication to requests library calls, enabling signed HTTP requests to AWS APIs and services.

Yes, if you need AWS SigV4 authentication with requests and are comfortable with dormant maintenance. The package is stable and has no known vulnerabilities, but it has not been updated since 2021-02-16. Install it for straightforward AWS API calls in Python; consider alternatives if you require active maintenance.

## Install

pip install requests-auth-aws-sigv4
uv add requests-auth-aws-sigv4
poetry add requests-auth-aws-sigv4

## Installing requests-auth-aws-sigv4

Before you install: Low install friction with a single runtime dependency (requests). Maintenance is dormant—last release was 2021-02-16 and last commit 2023-11-28. The package remains functional but receives no active updates.

License in practice: Licensed under Apache Software License (permissive), which allows commercial and private use with minimal restrictions.

Quickstart:

pip install requests-auth-aws-sigv4

import requests
from requests_auth_aws_sigv4 import AWSSigV4

aws_auth = AWSSigV4('sts')
r = requests.get('https://sts.us-east-1.amazonaws.com', auth=aws_auth)
print(r.text)

AWS credentials must be available via environment variables (AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY), boto3 configuration, or passed as parameters to AWSSigV4().

Verify before relying:

- Whether the package works correctly with current AWS API changes since its last update in 2021.
- Compatibility with recent versions of the requests library and modern Python 3.x releases.
- Whether dormant status affects real-world usage for typical AWS API calls.
