Sandbox / non-production only; returns 404 in production-live. The asset and network are resolved server-side from the Deposit Address (limited to ethereum, base, and solana); the caller supplies only the amount. ## OpenAPI ````yaml /api-reference/openapi.yaml post /deposit-addresses/{depositAddressId}/simulate/inbound-transfer openapi: 3.0.3 info: title: Polygon OMS Public API version: v26.05.28-0001 description: >- Unified API for moving money between crypto and fiat. Three ways to move money: Transactions (instant, wallet or card funded, including Cash-In for in-person cash deposits), Deposit Addresses (reusable crypto deposit configurations), and Virtual Accounts (dedicated bank accounts that auto-convert fiat to crypto). Standard transactions follow a two-step flow: create a Quote (pricing), then create a Transaction (execution). Cash-in codes generate a one-time deposit code for in-person cash deposits at retail locations. contact: name: Polygon OMS url: https://oms.polygon.technology servers: - url: https://sandbox-api.polygon.technology/v0.10 description: Sandbox - url: https://api.polygon.technology/v0.10 description: Production security: - BearerAuth: [] tags: - name: Auth description: Authentication via FrontEgg - name: Customers description: Customer management and KYC - name: Customer - name: Wallet - name: Quote - name: Transaction - name: Webhook - name: CashIns - name: CashLocation - name: Sandbox - name: VirtualAccount - name: Counterparty - name: ExternalAccount - name: DepositAddress paths: /deposit-addresses/{depositAddressId}/simulate/inbound-transfer: post: tags: - Sandbox summary: Simulate inbound transfer on a Deposit Address description: |- Simulate an inbound stablecoin (blockchain) transfer against a Deposit Address, for testing webhook and reconciliation flows.
