## What it is
IJPay is a lightweight Java payment SDK that wraps WeChat Pay, Alipay, QQ Pay, JD Pay, UnionPay, and PayPal into a unified, framework-agnostic toolkit. It can be embedded into any Java system without depending on any MVC framework, enabling rapid development of payment modules.

## Use cases
- integrate wechat pay into a java application
- add alipay payments to my backend
- accept unionpay and paypal payments in one library
- build a payment module without coupling to an mvc framework
- support multiple wechat pay merchants and api v3
- handle payment callback notifications in java

## When to choose
- you need multi-channel payment support (WeChat, Alipay, UnionPay, PayPal, JD, QQ) in a Java project
- you want a small, framework-agnostic library that embeds into any existing system
- you need WeChat Pay v2/v3 APIs, service-provider mode, or multi-merchant support

## When to avoid
- you need a full payment platform with settlement, reconciliation, or dashboard features
- your stack is not JVM-based
- you need payment channels not covered by the supported gateways

## Facets
- artifact type: library
- maturity: active
- function: sdk, http-client, webhook, developer-tools
- domain: fintech, e-commerce, web-development, backend, developer-tools
- platform: jvm, cross-platform
