Simulates an inbound wire, ACH or RTP deposit into a virtual account in the zerohash CERT environment, so you can test deposit handling without sending real money. The deposit then follows the same path as a real one: it is listed in the virtual account transactions and you receive the same deposit webhooks. Every request creates a new deposit; repeating a request creates another one. A virtual account that is not ACTIVE returns 409 Conflict with a message naming its status; an unknown id or an account belonging to another platform returns 404 Not Found. Not available in production.
