Community Python SDK for WeChat Pay API v3 — the de-facto standard for WeChat Pay v3 integration in Python. Covers direct merchant mode and service provider (partner) mode. Handles RSA signature generation, platform certificate auto-download and rotation, sensitive field encryption, and callback verification/decryption automatically. IMPORTANT: Multiple competing packages exist on PyPI (wechat_pay, pywechatpay, wechatpy, pywe-pay). Only 'wechatpayv3' targets the v3 API and is actively maintained. NOTE: This is a community SDK — WeChat Pay has no official Python SDK.
