Simulations (Sandbox only)
Unit's Sandbox environment provides additional operations on top of the regular APIs. Those operations allow you to easily test and simulate activities that would normally take a long time or require interaction with the external world.
A common example for testing would be Simulating a Received ACH Payment to create funds in an account, followed by Simulating a Card Purchase to spend those funds.
note
Simulation operations are subject to the same authentication scheme as the Live APIs, and therefore require a valid Authentication token.
