The event is processed exactly like a real provider deposit notification — asynchronously — so the response is an acknowledgement carrying the `(chain, txHash)` the deposit is detected under, not the deposit itself. Observe the deposit via the `transaction.created` webhook or `GET /v2/transactions?txHash=…`. Re-using a `(chain, txHash)` re-acknowledges the existing deposit rather than creating a second one. Sandbox supplies default sender information so happy-path deposits clear the deposit compliance gate automatically; the default is suppressed when the documented sender-information drivers fire (sourceAddress ending in DE5E11F1 or amount at/above the Travel Rule threshold) so the gate parks instead of clearing. Pass an explicit `originator` object to override the default and clear the gate. ## OpenAPI ````yaml https://api.sandbox.conduit.financial/v2/api-docs/openapi.json post /sandbox/customers/{customerId}/wallets/{walletId}/deposits/simulate openapi: 3.0.0 info: title: Conduit Sandbox API description: >- **Sandbox API** — clients integrate against this surface to exercise happy and unhappy paths without consuming real KYC/PSP credits or moving real money.
