openapi: 3.1.0 info: title: Increase Account Numbers Wire Transfers API description: Increase is a bank-grade payments and financial infrastructure platform that exposes a single REST API for moving and holding money in the United States. This document models the primary resources of the Increase API - Accounts, Account Numbers, Cards, Card Payments, ACH / Wire / Real-Time Payments / Check transfers, Transactions, Entities, Events and webhooks, Bookkeeping, Card Profiles and Digital Wallets, Lockboxes, and Simulations. It is grounded in Increase's public OpenAPI 3.1 spec (https://api.increase.com/openapi.json) and the Stainless-generated SDKs. Authentication is a Bearer API key. All endpoints are HTTPS REST; state changes are delivered as Events over HTTP webhooks (no WebSocket surface). Requests support idempotency via the `Idempotency-Key` header. This is a representative, not exhaustive, subset of the full API. version: 0.0.1 contact: name: Increase url: https://increase.com license: name: Increase Documentation url: https://increase.com/documentation servers: - url: https://api.increase.com description: Production - url: https://sandbox.increase.com description: Sandbox security: - bearerAuth: [] tags: - name: Wire Transfers description: Fedwire transfers and drawdown requests. paths: /wire_transfers: get: operationId: listWireTransfers tags: - Wire Transfers summary: List Wire Transfers responses: '200': description: A list of Wire Transfers. content: application/json: schema: type: object properties: data: type: array items: $ref: '#/components/schemas/WireTransfer' post: operationId: createWireTransfer tags: - Wire Transfers summary: Create a Wire Transfer requestBody: required: true content: application/json: schema: type: object required: - account_id - amount - message_to_recipient properties: account_id: type: string amount: type: integer message_to_recipient: type: string beneficiary_name: type: string account_number: type: string routing_number: type: string external_account_id: type: string responses: '200': description: The created Wire Transfer. content: application/json: schema: $ref: '#/components/schemas/WireTransfer' /wire_transfers/{wire_transfer_id}: parameters: - name: wire_transfer_id in: path required: true schema: type: string get: operationId: retrieveWireTransfer tags: - Wire Transfers summary: Retrieve a Wire Transfer responses: '200': description: The Wire Transfer. content: application/json: schema: $ref: '#/components/schemas/WireTransfer' /wire_transfers/{wire_transfer_id}/approve: parameters: - name: wire_transfer_id in: path required: true schema: type: string post: operationId: approveWireTransfer tags: - Wire Transfers summary: Approve a Wire Transfer responses: '200': description: The approved Wire Transfer. content: application/json: schema: $ref: '#/components/schemas/WireTransfer' /wire_transfers/{wire_transfer_id}/cancel: parameters: - name: wire_transfer_id in: path required: true schema: type: string post: operationId: cancelWireTransfer tags: - Wire Transfers summary: Cancel a pending Wire Transfer responses: '200': description: The canceled Wire Transfer. content: application/json: schema: $ref: '#/components/schemas/WireTransfer' /wire_drawdown_requests: post: operationId: createWireDrawdownRequest tags: - Wire Transfers summary: Create a Wire Drawdown Request requestBody: required: true content: application/json: schema: type: object required: - account_number_id - amount - recipient_account_number - recipient_routing_number properties: account_number_id: type: string amount: type: integer recipient_account_number: type: string recipient_routing_number: type: string recipient_name: type: string responses: '200': description: The created Wire Drawdown Request. content: application/json: schema: type: object additionalProperties: true components: schemas: WireTransfer: type: object properties: id: type: string account_id: type: string amount: type: integer message_to_recipient: type: string beneficiary_name: type: string nullable: true status: type: string enum: - pending_approval - pending_creating - submitted - complete - canceled - reversed type: type: string example: wire_transfer securitySchemes: bearerAuth: type: http scheme: bearer description: 'Increase API key passed as `Authorization: Bearer YOUR_API_KEY`.
