# LP Simulation

The Liquidity Provider Simulation has the Pay For Order `POST` api endpoint to ensure payment is successful between a payment provider and a consumer in a sandboxed or test environment. This validates successful funding from the provider to the customer and completes the order.

There are two endpoints in this section. They are:

* [Pay for order (Buy Order)](https://doc.xendbridge.com/api-method-calls/broken-reference)
* [Pay for order (Sell Order)](https://doc.xendbridge.com/api-method-calls/broken-reference)
