flask-request-id-header
Python Flask middleware to ensure all requests have a request ID header
Decision gist · record as of 2026-08-14
Yes, if you need a minimal, zero-configuration request ID middleware for a Flask application and can accept that the package is unmaintained. It has no known vulnerabilities, low install friction, and a simple, stable API. No, if you require active maintenance, support for recent Flask versions, or a more feature-rich tracing solution. Verify the Open Government Licence v3.0 is acceptable for your use case.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Installation is straightforward with low friction—only flask as a runtime dependency.
- However, the package is abandoned: last release was 2019-03-02, last commit 2022-12-27, and no maintenance activity since.
- Use only if you need a minimal, stable request ID middleware and can maintain it yourself if needed.

What it is and what it does
Flask Request ID Header is a lightweight middleware that ensures every HTTP request to a Flask application carries a unique X-Request-ID header. If a request arrives without one, the middleware generates a UUID v4 and adds it; if one exists but lacks a UUID v4 value, the middleware appends one. This enables request tracing across microservices, load balancers, and reverse proxies—critical for correlating log entries and debugging distributed systems.
The middleware integrates directly into Flask's request handling with no required configuration. It exposes the current request ID via the request environment (HTTP_X_REQUEST_ID) so your application code can access it for logging or forwarding. You can optionally set a REQUEST_ID_UNIQUE_VALUE_PREFIX config to treat certain prefixed IDs as already unique, preventing unnecessary appends. The package is minimal and stable but unmaintained since 2019.
Use it for
- Trace a single user request through multiple microservices by including the X-Request-ID in logs at each layer.
- Correlate errors in a load-balanced Flask deployment by extracting the request ID from response headers.
- Include request IDs in application logs using a custom logging formatter to link log entries to specific user actions.
- Pass request IDs downstream to external APIs or databases to maintain end-to-end request context in distributed systems.
