# Simulate a fixed-route source deposit

`POST /v1/sandbox/fixed-routes/{id}/simulate-deposit`

Sandbox-only: triggers the fixed-route sweep without on-chain funds or provider webhooks. Works for fiat (`vba_`) and crypto (`inw_`) source routes. Does not use account fund-in -- Infinite wallets cannot be credited that way. Idempotent when `reference` is reused. Wire/FedWire/SWIFT deposits populate `source.originator` with a sandbox remitter unless you pass `originator` or the route has `allowedSenderBanks`.

## Path parameters

- `id` string, required

## Headers

- `X-API-Key` string

## Request body

- SandboxSimulateFixedRouteDepositDto
  - `amount` string, required — Deposit amount in major units (e.g. "1000.00" for USD, "100.5" for USDT)
  - `currency` string — Deposit currency; defaults to the route source currency when omitted
  - `reference` string — Idempotency reference for the simulated deposit; replays return the existing sweep transfer
  - `senderBank` AllowedSenderBankDto
    - `bankName` string — Sender bank name. Matched ignoring case, whitespace, and punctuation.
    - `routingNumber` string — Sender bank routing number (e.g. US ABA). Matched on digits only.
    - `swiftBic` string — Sender bank SWIFT/BIC code (8 or 11 characters)
  - `originator` SandboxDepositOriginatorDto
    - `name` string — Originator / remitter name
    - `bankName` string — Originating bank name
    - `routingNumber` string — Originating bank routing number (e.g. US ABA)
    - `accountNumber` string — Originating account number or IBAN
    - `swiftBic` string — Originating bank SWIFT/BIC
    - `bankCountry` string — ISO 3166-1 alpha-2 country of the originating bank. Inferred from routing/BIC/IBAN when omitted.
