google-auth-httplib2
Google Authentication Library: httplib2 transport
Decision gist · record as of 2026-08-14
Yes, but only if you are actively migrating from oauth2client to google-auth and cannot immediately replace httplib2. For new projects, use google-auth's built-in transport layers instead. The package is actively maintained and carries no known vulnerabilities, but httplib2 itself has documented thread-safety and TLS security issues that make it unsuitable for new development.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.10 or later.
- httplib2 has known thread-safety and TLS security issues; the package documentation discourages its use except for migration from oauth2client.
- Low install friction with only two runtime dependencies (google-auth and httplib2).

Verify before relying

- Specific security implications of using httplib2 beyond the general warnings in the documentation.
What it is and what it does
google-auth-httplib2 is a transport adapter that bridges the deprecated httplib2 HTTP client library with Google's modern google-auth authentication library. It exists primarily as a migration path for code that was previously built on oauth2client and httplib2, allowing those projects to adopt google-auth without immediately replacing their HTTP client layer.
The package is lightweight, depending only on google-auth and httplib2 itself. However, the documentation explicitly warns that httplib2 has significant problems including lack of thread-safety and insecure TLS usage, and recommends using google-auth's own transport layers for new code. It is intended as a temporary bridge for legacy systems, not as a foundation for new projects.
Use it for
- Migrating oauth2client-based authentication code to google-auth while keeping httplib2 as the HTTP transport.
- Maintaining existing applications that depend on httplib2 without rewriting their HTTP layer during an auth library upgrade.
- Providing backward compatibility in legacy systems where replacing httplib2 is not immediately feasible.

Before you install
Low install friction with only two runtime dependencies (google-auth and httplib2). Actively maintained as of 2026-08-14 with recent releases, though the package itself is explicitly marked as no longer maintained in favor of google-auth's own transport layers.
Requires Python 3.10 or later. httplib2 has known thread-safety and TLS security issues; the package documentation discourages its use except for migration from oauth2client.
