PDPYRAS: PagerDuty Python REST API Sessions

A module that supplies lightweight Python clients for the PagerDuty REST API v2 and Events API v2.

For how-to, refer to the User Guide.

Overview

This library supplies classes extending requests.Session from the Requests HTTP library that serve as Python interfaces to the REST API v2 and Events API v2 of PagerDuty. One might call it an opinionated wrapper library. It was designed with the philosophy that Requests is a perfectly adequate HTTP client, and that abstraction should focus only on the most generally applicable and frequently-implemented core features, requirements and tasks. Design decisions concerning how any particular PagerDuty resource is accessed or manipulated through APIs are left to the user or implementer to make.

Features

• Uses Requests' automatic HTTP connection pooling and persistence
• Tested in / support for Python 3.6 through 3.10
• Abstraction layer for authentication, pagination, filtering and wrapped entities
• Configurable cooldown/reattempt logic for handling rate limiting and transient HTTP or network issues

History

This module was borne of necessity for a basic API client to eliminate code duplication in some of PagerDuty Support's internal Python-based API tooling.

We found ourselves frequently performing REST API requests using beta or non-documented API endpoints for one reason or another, so we needed the client that provided easy access to features of the underlying HTTP library (i.e. to obtain the response headers, or set special request headers). We also needed something that eliminated tedious tasks like querying objects by name, pagination and authentication. Finally, we discovered that the way we were using Requests wasn't making use of its connection pooling feature, and wanted a way to easily enforce this as a standard practice.

We evaluated at the time a few other open-source API libraries and deemed them to be either overkill for our purposes or not giving the implementer enough control over how API calls were made.
