Simulate a Transaction

Changed on

Note This endpoint is only available in Sandbox.

Create a Transaction by simulating the attributes that would be expected from reading an actual transaction received from a third party system. The simulated Transaction will appear in the respective Transaction list after it is successfully processed.

Transactions can be simulated against either a Synthetic Account, or a VRN that is created and mapped to a Synthetic Account.
