# Poynt Cloud
There are several way of integrating an external POS with Poynt:
- Payment Bridge API. This API provides support for basic sale, void and refund operations.
- Using PnP button which requires no API integration. Payment button can be embed in your web-based POS using our javascript snippet.
- Implementing your own communication protocol leveraging Poynt Cloud API. This is the most flexible option but requires more integration effort from the developer.
# Local Network
POS Bridge is a free app that can be downloaded by merchants via Poynt Store. The POS app will need to use either Poynt iOS or Windows SDK to connect to the terminal.
# Other
Since PoyntOS is based on Android, developers have a wide array of options and can implement their own connector using USB, Bluetooth, web sockets, etc.
