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/v0.11 description: Sandbox - url: https://api.polygon.technology/v0.11 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: CashIns - name: CashLocation - name: Sandbox - name: VirtualAccount - name: Counterparty - name: ExternalAccount - name: DepositAddress paths: /webhooks/{webhookId}/deliveries/{deliveryId}: get: tags: - Webhooks summary: Get a delivery with its attempts operationId: getWebhookDelivery parameters: - name: webhookId in: path required: true schema: type: string - name: deliveryId in: path required: true schema: type: string responses: '200': description: Delivery with attempts content: application/json: schema: $ref: '#/components/schemas/GetDeliveryResponse' '401': description: Unauthorized content: application/json: schema: $ref: '#/components/schemas/ErrorResponse' '404': description: Not Found content: application/json: schema: $ref: '#/components/schemas/ErrorResponse' components: schemas: GetDeliveryResponse: type: object required: - delivery - attempts properties: delivery: $ref: '#/components/schemas/WebhookDelivery' attempts: type: array items: $ref: '#/components/schemas/DeliveryAttempt' ErrorResponse: type: object required: - error - code - msg - status description: >- Canonical OMSX error envelope, matching the webrpc shape every OMSX service emits.
