asgi-correlation-id
Middleware correlating project logs to individual requests
Decision gist · record as of 2026-08-14
Yes. The package is production-stable (Development Status 5), has no known vulnerabilities, minimal dependencies, and solves a common observability problem in ASGI applications. Install it if you need to correlate logs across your application; the setup overhead is low and the debugging value is high.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.10 or later; logging must be configured separately to include correlation_id in the format string.
- Low friction: pure Python wheel with a single runtime dependency on starlette.
- Actively maintained with recent releases; last commit 2026-06-09 and 638 repository stars indicate steady adoption and support.

What it is and what it does
This package provides ASGI middleware that attaches a unique correlation ID to each incoming HTTP request, either by reading an existing ID from a header (like X-Request-ID or X-Correlation-ID) or by generating a new one. The middleware stores this ID in a way that makes it accessible to your application's logging system, allowing you to tag all log messages from a single request with the same ID.
The primary use case is request tracing: when logs from different parts of your application are all tagged with the same correlation ID, you can easily retrieve and correlate all logs belonging to a single user request. The package integrates with Python's standard logging module via a filter and supports customization of header names, ID generation, validation, and transformation.
Use it for
- Debugging production issues by filtering logs to show only those from a specific user request.
- Tracing requests across multiple services when correlation IDs are propagated through HTTP headers.
- Integrating with error tracking services to group errors by the request that triggered them.
- Auditing and compliance logging where you need to track all actions during a specific request.
- Correlating logs from multiple handlers or middleware layers processing the same incoming request.
