2025-10-24: 6.0.0: Change base HTTP client to python-httpx

The underlying HTTP client on which this library is based has been changed to python-httpx. The primary motivation of this change is to provide thread safety with a very similar interface to requests, and the possibility to add support for asynchronous usage in future releases.

  • Breaking Changes:

    • The proxies property no longer exists in client classes, and proxy configuration must be passed to the constructor in one of the proxy or mounts keyword arguments. See: HTTPX: Advanced: Proxies

    • Response objects no longer have an ok property; use is_success instead.

    • The following deprecated properties and methods have been removed:

      • ApiClient.auth_header

      • RestApiV2BaseClient.after_set_api_key

      • RestApiV2BaseClient.api_key

    • The deprecated keyword argument routing_key to EventsApiV2Client.send_change_event has been removed.

    • Support for the deprecated Response Plays API has been removed from RestApiV2Client.

2025-10-23: 5.3.0: New AuthMethod class for verbatim authorization header setting

  • New authentication method class PassThruHeaderAuthMethod that treats the secret as the whole content of the Authorization header.

2025-10-13: 5.2.0: New clients for new APIs

  • Client class ScimApiClient for the PagerDuty SCIM API

  • Client class McpApiClient for the PagerDuty MCP API

2025-10-01: 5.1.0: Maintenance update with entity wrapping support for new API endpoints

  • Entity wrapping support added for endpoints including:

    • Incident types API

    • Webhooks API

    • Event Orchestrations cache variables

    • Per-service custom fields

    • OAuth clients (webhook subscriptions)

  • Entity wrapping support not yet removed for deprecated APIs i.e. “Response Plays” to avoid breaking changes.

2025-09-24: 5.0.0: API authentication interface refactor

In this version, the details of how authentication are performed are offloaded to a new class, AuthMethod. Each instance of ApiClient have a new property, auth_method, which is an instance of AuthMethod. This provides a generic framework for implementing all the forms of authentication (using headers or parameters in the request body) utilized in all of PagerDuty’s APIs, minimizing redundant code in ApiClient subclasses.

The primary motivation of this change was to make the behavior of REST API v2 client objects more stable and predictable when swapping out their API credentials mid-process. This is needed for the purposes of an internal project at PagerDuty.

  • Breaking Changes:

    • The api_key property has been removed from all client classes except for pagerduty.RestApiV2BaseClient and subclasses thereof, wherein it is deprecated.

    • The hook method after_set_api_key will be ignored in all classes where the api_key property has been removed.

2025-09-08: 4.1.1: Bugfix: iter_all parameter serialization

  • Fixes a regression wherein a boolean is serialized to the capitalized True / False for the total parameter in classic pagination, whereas the API requires lower case values.

2025-08-27: 4.1.0: Feature: PKCE OAuth helpers

  • Feature: new methods get_new_token_from_code_with_pkce, generate_s256_pkce_params and get_pkce_authorize_url of pagerduty.OAuthTokenClient to assist with implementation of the OAuth via PKCE token grant flow.

2025-08-18: 4.0.1: Bugfix: export all features currently imported to the root namespace

  • Fixes: adds an explicit __all__ declaration to the root pagerduty module namespace for all members that are currently imported to that namespace.

2025-08-12: 4.0.0: REST API Base Client Refactor + New Clients

  • Breaking Changes:

    • Deprecated property RestApiV2Client.trunc_token has been removed.

    • Helper functions have been moved; any namespaced references to them will need to be updated. References to them in the root pagerduty namespace will not be affected; they are still imported there for backwards compatibility. The changes are as follows:

      • Helper functions last_4 and normalize_url have been moved from pagerduty.api_client to pagerduty.common.

      • Helper functions endpoint_matches, is_path_param, infer_entity_wrapper and unwrap have been moved from pagerduty.rest_api_v2_client to pagerduty.rest_api_v2_base_client.

      • Function decorators auto_json, resource_url and wrapped_entities have been moved from pagerduty.rest_api_v2_client to pagerduty.rest_api_v2_base_client.

  • New Features: API client classes for the integration APIs that share many of the same features of pagerduty.RestApiV2Client:

    • pagerduty.SlackIntegrationApiClient and pagerduty.SlackIntegrationConnectionsApiClient provide support for the PagerDuty Slack Integration API.

    • pagerduty.MsTeamsIntegrationApiClient provides support for the PagerDuty MS Teams Integration API.

    • pagerduty.JiraServerIntegrationApiClient provides support for the PagerDuty Jira Server Integration API.

    • pagerduty.JiraCloudIntegrationApiClient provides support for the PagerDuty Jira Cloud Integration API.

  • Fixes and Refactoring:

    • HTTP request headers:

      • Duplicate code has been removed from the prepare_headers method in all client classes and consolidated into pagerduty.ApiClient.

      • The Content-Type header is now added when making PATCH requests in REST API v2.

    • New REST API base class pagerduty.RestApiV2BaseClient brings automatic entity wrapping and pagination helpers to new APIs outside of REST API v2

    • The total query parameter sent to the API by iter_all is now a boolean as it needs to be according to the API documentation.

    • New descriptive types for canonical paths and entity wrapping

    • The get_total method of REST API client classes now tests for a successful response before checking the response schema in order to raise the correct type of exception.

2025-07-15: 3.1.0: New features

  • New features in RestApiV2Client

    • Abstraction for endpoints that implement non-standard styles of pagination

    • Iterator method for incident notes

    • Method for testing if the account has a given ability

  • Fix: Update the “Unknown version” (for versioned user-agent headers in Python prior to version 3.8) and add a test to validate that it is up to date with the true current major version

2025-07-08: 3.0.0: New features

  • Breaking Change: the method ApiClient.normalize_params no longer modifies parameters. The implementation of it that previously did, which was meant only for the child class RestApiV2Client, has been migrated to that class as an override.

  • New Features:

    • New method OAuthTokenClient.refresh_client: instantiates and returns a RestApiV2Client instance and auto-refreshes the access token

    • New method RestApiV2Client.iter_history: iterates through large historical data sets that exceed the hard limit of classic pagination

    • New method RestApiV2Client.get_total: returns the total number of matching records in a classic pagination endpoint

    • Expanded coverage of type hints

    • Documentantion revisions

  • Fixes:

    • Method RestApiV2Client.rpatch now fully implemented (it mistakenly was left with no return value in previous versions)

    • Mutable default values in optional keyword arguments have been replaced with None.

2025-06-23: 2.3.0: Add a new OAuth token exchange client class

  • This version introduces a new client class for obtaining OAuth tokens using code grant / token refresh or for a scoped app.

2025-06-03: 2.2.0: Add py.typed marker file

  • Add a py.typed marker file so that type checkers recognize that pagerduty supports type checking.

2025-05-19: 2.1.2: Bug fixes for iter_cursor and HTTP 204 response handling

  • Allow try_decoding to return None for empty input; fixes GitHub issue #46.

  • Non-breaking changes to RestApiV2Client.iter_cursor, to fix GitHub issue #45:

    • It now uses the default_page_size client setting as the limit parameter.

    • It accepts a page_size parameter that can override said default (and params can also override this default), similar to iter_all.

    • When called indirectly via iter_all, the item_hook keyword argument is passed through to it, along with page_size.

2025-05-14: 2.1.1: Bug fix

  • The “main” method in the entry script is expected to receive no arguments, but in v2.1.0, it requires one positional argument.

2025-05-13: 2.1.0: Command line interface

  • Add a basic command line interface for Events API v2, for feature parity with the legacy library that is used in the Monit Integration Guide.

2025-04-08: 2.0.0: Multi-file refactor

This release introduces major structural changes to the module and how it is built and tested. These changes were made for long-term maintainability of the codebase. Previously, it was all contained within a monolithic .py file (with a single Python script for all unit tests); now it is organized into smaller, appropriately-named Python files.

Some lesser changes are also included:

  • The docstrings for the submit and send_change_event methods of EventsApiV2Client have been updated to reflect how they are expected to always return None; this was causing Airflow build failures.

  • The default user agent header has been updated: the prefix has been changed from pagerduty to python-pagerduty.

  • The version number pagerduty.__version__ is now maintained in pyproject.toml and discovered through package metadata introspection at import time. In Python versions prior to 3.8, the version will be 2.*.* because the new importlib feature required for it is unavailable.

2025-01-02: 1.0.0: Migrate from PDPYRAS

  • BREAKING CHANGE: class names have changed from what they were in pdpyras; see: PDPYRAS Migration Guide

  • The REST API client now supports new status page, event orchestrations, custom incident fields, OAuth delegations and alert grouping settings APIs.
