# Getting started

Resolve offers both server-side and client-side integrations.
This documentation refers to the server-side API.
Refer to our [e-commerce plugin guides](https://docs.resolvepay.com/docs/) for details on client-side checkout solutions.

There is a sandbox API available for testing, which leverages the same data store as your sandbox dashboard. Testing on sandbox won't affect your live data or create money movements.
