Wayfair Integration Guide
Integrate Wayfair supplier operations with enterprise systems through approved REST APIs, partner callbacks, and account-specific file or EDI processes.
Wayfair integration options at a glance
Wayfair supplier integrations primarily use partner-facing REST APIs, with available resources and permissions determined by the supplier program, region, and enabled API products. These APIs can support operations for Orders, Products, Inventory, Shipments, and Returns. Selected partner processes may also provide notifications or callbacks, although broad webhook coverage is not confirmed. Larger exchanges may use account-specific batch, asynchronous, file, or EDI processes. Martini can authenticate with Wayfair-provisioned credentials, schedule incremental retrievals, submit updates, transform payloads, validate business rules, and expose internal APIs for downstream systems.
| Integration point | Supported by Wayfair? | Common use cases | How Martini supports it |
|---|---|---|---|
| REST APIs | Yes | Wayfair supplier APIs can support Orders, Products, Inventory, Shipments, and Returns, subject to the supplier program and enabled API products. | Martini can consume documented Wayfair REST endpoints, schedule retrievals, submit updates, transform responses, and expose APIs for downstream applications. |
| Webhooks and outbound callbacks | Limited | Selected partner processes may provide notifications or callbacks, but broad coverage across Wayfair business objects is not confirmed. | Martini can receive supported webhook-style notifications or callbacks and use them to start workflows that retrieve the current Wayfair resource. |
| Bulk, asynchronous, and batch APIs | Limited | Large-volume exchanges may be available through specific API products or supplier processes; operation-specific behavior must be verified. | Martini can orchestrate batch workflows, checkpoint progress, partition large workloads, and handle asynchronous completion where the documented process supports it. |
| File and EDI exchange | Limited | Some suppliers may use file-based or EDI-oriented processes for catalog, orders, inventory, or fulfillment exchanges. | Martini can orchestrate supported file processes, parse applicable formats, map records, validate batches, and route rejected rows for remediation. |
| Authentication | Yes | Wayfair supplier API access requires provisioned application or supplier credentials, with the exact token flow and permissions depending on the account. | Martini can store credentials in secrets or protected environment configuration and use the confirmed token-based authentication flow for API requests. |
| GraphQL APIs | Not confirmed | No official Wayfair GraphQL API was confirmed for the supplier integration scenario. | Martini should use the documented Wayfair REST or approved partner process instead of assuming GraphQL availability. |
| SOAP APIs | Not confirmed | No current official Wayfair SOAP API was confirmed for the supplier integration scenario. | Martini should not assume SOAP support and can use the confirmed Wayfair API or file-based mechanism for the required operation. |
| Database access | No | Wayfair does not provide public direct database access for supplier integrations. | Martini can persist checkpoints or canonical data in an approved internal database, while obtaining Wayfair data through APIs, exports, or partner processes. |
How Wayfair exposes data and business events
Wayfair REST APIs
Wayfair supplier integrations are primarily associated with partner-facing REST APIs. Available resources, operations, fields, and permissions depend on the supplier account, region, program, and enabled API products.
Martini implementation pattern
Martini implementation pattern: a workflow authenticates with Wayfair-provisioned credentials, retrieves or submits the required resource, handles pagination and incremental filters, maps the payload to a canonical model, applies validation and business rules, and writes the result to downstream systems.
Implementation sequence
Wayfair callbacks
Selected Wayfair partner processes may provide event notifications or outbound callbacks, but broad webhook coverage for Orders, Products, Inventory, Shipments, and Returns is not confirmed.
Martini implementation pattern
Martini implementation pattern: receive a supported callback, validate its source and event details, then retrieve the current Wayfair resource through the applicable API before applying business processing. Polling remains necessary where callbacks are unavailable.
Implementation sequence
Wayfair batch and file processes
Some Wayfair supplier programs may support large-volume, asynchronous, batch, file, or EDI-oriented exchanges for catalog, order, inventory, or fulfillment data. Exact formats and transport methods require account confirmation.
Martini implementation pattern
Martini implementation pattern: obtain or produce the approved batch or file, parse and validate each item, process successful records independently where possible, and preserve row-level errors for correction and replay.
Implementation sequence
Common Wayfair integration patterns
Pattern 1: Sync Wayfair orders to an ERP
When to use this pattern
Use this pattern when an ERP or order-management platform must receive new or changed Wayfair Orders. Scheduled retrieval is appropriate when event coverage is unavailable or not confirmed.
Integration direction
Example Mapping
| Wayfair Field | Canonical Field | Target Field |
|---|---|---|
| orderId | externalOrderId | externalId |
| orderStatus | orderStatus | status |
| lineItems[].sku | itemSku | item |
| lineItems[].quantity | orderedQuantity | quantity |
Martini implementation pattern
A scheduler starts a workflow that retrieves Orders using documented pagination and an overlap window. Martini validates addresses, line items, quantities, and identifiers, maps the payload to the ERP model, applies duplicate checks, writes the order, and routes authentication, throttling, validation, or downstream failures to bounded retry and error handling paths.
Martini capabilities used
- workflows
- API consumption
- scheduling
- data mapping
- business rules
- idempotency
- error handling
Pattern 2: Send inventory updates to Wayfair
When to use this pattern
Use this pattern when Wayfair should receive available-to-sell quantities from an ERP, warehouse, or fulfillment platform.
Integration direction
Example Mapping
| Wayfair Field | Canonical Field | Target Field |
|---|---|---|
| sku | productSku | sku |
| availableQuantity | availableToSell | quantity |
| warehouseCode | fulfillmentLocation | location |
| updatedAt | inventoryAsOf | effectiveAt |
Martini implementation pattern
Martini reads inventory from the authoritative source, applies safety-stock and reserved-quantity rules, resolves SKU cross-references, and submits updates through the Wayfair inventory process enabled for the supplier. Responses are reconciled, temporary failures are retried with backoff, and rejected items are retained for correction.
Martini capabilities used
- workflows
- API consumption
- data mapping
- business rules
- validation
- retry handling
Pattern 3: Submit shipment updates from fulfillment
When to use this pattern
Use this pattern when a warehouse, transportation, or order-management system produces fulfillment information that must be sent to Wayfair.
Integration direction
Example Mapping
| Wayfair Field | Canonical Field | Target Field |
|---|---|---|
| orderId | externalOrderId | orderId |
| trackingNumber | trackingNumber | trackingNumber |
| carrier | carrierCode | carrier |
| shippedQuantity | fulfilledQuantity | quantity |
Martini implementation pattern
A workflow retrieves completed fulfillment data, maps carrier, tracking, date, order, and line-item identifiers, validates the shipment state, and submits the Wayfair Shipments update. Split shipments are handled as separate transactions where supported, while deterministic keys prevent duplicate submissions.
Martini capabilities used
- workflows
- API consumption
- data mapping
- business rules
- idempotency
- error handling
Pattern 4: Synchronize products and catalog data
When to use this pattern
Use this pattern when a product information system or ERP must publish product attributes and identifiers through the Wayfair process enabled for the supplier.
Integration direction
Example Mapping
| Wayfair Field | Canonical Field | Target Field |
|---|---|---|
| itemSku | productSku | supplierSku |
| productName | productTitle | title |
| dimensions | productDimensions | dimensions |
| imageReference | mediaReference | image |
Martini implementation pattern
Martini retrieves product data, transforms attributes and identifiers into the account-specific Wayfair model, validates required catalog fields, and submits records in a batch or API workflow. Invalid products are separated with validation details so successful records can proceed without hiding remediation work.
Martini capabilities used
- workflows
- API consumption
- data mapping
- validation
- batch orchestration
- error handling
Applications commonly integrated with Wayfair
Wayfair can be integrated with the named enterprise applications below as part of a marketplace, commerce, fulfillment, or retail data architecture. These are common architecture targets rather than confirmed Wayfair-certified integrations, so enabled APIs and partner processes should be verified for each account.
| Application | Scenario | Direction | Martini Pattern |
|---|---|---|---|
| NetSuite | Synchronize Wayfair orders, inventory, fulfillment, returns, and financial reconciliation with ERP processes. | Wayfair → Martini → NetSuite | A scheduled workflow retrieves Orders and Returns from Wayfair, maps them to NetSuite transactions, and sends inventory and shipment updates from NetSuite back through the applicable Wayfair API. Martini stores source identifiers, validates payloads, and routes rejected transactions for review. |
| SAP S/4HANA | Connect marketplace orders and fulfillment information with enterprise order, inventory, and finance processes. | Wayfair → Martini → SAP S/4HANA | Martini orchestrates bidirectional REST-based exchanges, normalizes product and order identifiers, applies inventory and fulfillment rules, and records checkpoints so retries do not create duplicate transactions. |
| Microsoft Dynamics 365 | Align Wayfair sales orders, inventory, shipments, and returns with Microsoft business operations. | Wayfair → Martini → Microsoft Dynamics 365 | A workflow retrieves changed Wayfair Orders and Returns, maps them to Dynamics 365 structures, and submits outbound inventory or shipment updates after validation and business-rule checks. |
| Shopify | Keep marketplace catalog, inventory, and order information aligned with a direct-to-consumer commerce operation. | Wayfair → Martini → Shopify | Martini maintains a canonical product and inventory model, transforms identifiers and quantities between systems, and uses scheduled workflows with overlap windows and idempotent writes for reconciliation. |
| Salesforce Commerce Cloud | Coordinate marketplace product and inventory information with a branded commerce storefront. | Wayfair → Martini → Salesforce Commerce Cloud | Martini retrieves or receives account-approved Wayfair data, maps catalog and inventory attributes to storefront models, and sends validated updates through the target system's APIs. |
| ShipStation | Consolidate Wayfair orders and shipment tracking with carrier and fulfillment workflows. | Wayfair → Martini → ShipStation | A workflow maps Wayfair Orders into ShipStation fulfillment requests, consumes shipment and tracking data, and submits Shipments back to Wayfair with retry and duplicate-protection controls. |
| SPS Commerce | Use a retail integration service to exchange orders, inventory, and fulfillment data where the supplier program supports the process. | Wayfair → Martini → SPS Commerce | Martini coordinates API or approved file/EDI exchanges, converts partner-specific formats into canonical order and fulfillment models, and isolates rejected records for correction and replay. |
| Manhattan Active | Coordinate marketplace orders, inventory, and fulfillment execution with an enterprise fulfillment platform. | Wayfair → Martini → Manhattan Active | Martini synchronizes Wayfair order and inventory data with Manhattan Active, applies warehouse and quantity rules, and sends shipment status updates after confirming source identifiers and fulfillment state. |
How to build a Wayfair integration in Martini
Objective

Common Wayfair data objects used in integrations
| Object | Typical Use | Common target systems | Martini handling |
|---|---|---|---|
| Orders | Retrieve customer orders routed to the supplier, acknowledge or process them, and create downstream sales orders. | NetSuite, SAP S/4HANA, Microsoft Dynamics 365, ShipStation | Martini retrieves Orders incrementally, applies pagination and validation, maps identifiers and line items, and records source IDs for idempotency. |
| Products | Synchronize catalog identifiers, attributes, merchandising information, and product content. | Shopify, Salesforce Commerce Cloud, NetSuite, SAP S/4HANA | Martini transforms product attributes and identifiers into target models, validates required catalog fields, and preserves rejected records for remediation. |
| Inventory | Exchange available-to-sell quantities and inventory updates between supplier systems and Wayfair. | NetSuite, SAP S/4HANA, Microsoft Dynamics 365, Manhattan Active | Martini reads authoritative quantities, applies safety-stock or reservation rules, maps SKUs, submits updates, and reconciles accepted and rejected responses. |
| Shipments | Submit fulfillment, carrier, tracking, ship-date, and shipment-status information. | ShipStation, Manhattan Active, NetSuite, SAP S/4HANA | Martini maps order and line-item identifiers, carrier codes, tracking numbers, and split-shipment details before submitting validated updates. |
| Returns | Process returned items, return authorizations, and return-status information. | NetSuite, SAP S/4HANA, Microsoft Dynamics 365, SPS Commerce | Martini retrieves or submits return information where enabled, maps statuses and quantities, and links return activity to the original order. |
| Suppliers | Represent supplier account or relationship information where exposed by the applicable API. | ERP, supplier operations platforms, internal master-data services | Martini can synchronize exposed supplier attributes while respecting account permissions and avoiding assumptions about unavailable fields. |
Authentication and security considerations
Account-specific access
Wayfair API access is provisioned for approved suppliers, and the exact credentials, token flow, scopes, and resources depend on the supplier program and enabled API products.
Credential protection
Store Wayfair application credentials and tokens in Martini secrets or protected environment configuration. Do not place secrets in workflow source, logs, or error payloads.
- Use separate sandbox and production configuration where available.
- Restrict permissions to the required Wayfair operations.
- Mask customer, address, and authentication data in operational logs.
Operational considerations for Wayfair integrations
Throughput and pagination
Use documented pagination and server-side filters where available. Confirm Wayfair rate limits and operation-specific batch behavior before selecting polling intervals or concurrency levels.
Reliability
- Use overlap windows and persisted high-water marks for incremental retrieval.
- Retry transient throttling and server failures with bounded exponential backoff.
- Do not retry unchanged validation failures.
- Use deterministic identifiers for idempotency and reconciliation.
Change management
Wayfair schemas, API versions, and program-specific validation rules may change. Test representative Orders, Products, Inventory updates, split Shipments, cancellations, and Returns before production changes.
Monitoring
Monitor response codes, token failures, pagination progress, rejected records, processing latency, and accepted versus failed updates. Preserve correlation identifiers and support replay without reprocessing committed transactions.
Why use Martini instead of scripts or point-to-point integrations?
Centralized orchestration
Martini coordinates Wayfair API calls, scheduled retrievals, callbacks where supported, transformations, validations, and downstream writes in workflows rather than scattering logic across scripts.
Maintainable data movement
Explicit mappings, reusable workflow logic, canonical models, and protected configuration make marketplace integrations easier to change as Wayfair programs and target systems evolve.
Operational control
Martini provides structured error handling, retry paths, checkpoints, logging, and replay-oriented processing for orders, inventory, shipments, products, and returns.
Controlled APIs
Where appropriate, Martini can expose an internal API façade that hides Wayfair-specific authentication and mapping details from downstream applications.
Frequently asked questions
Wayfair supplier integrations primarily use approved partner-facing REST APIs for Orders, Products, Inventory, Shipments, and Returns. Depending on the supplier program, selected callbacks, batch or asynchronous operations, and file or EDI processes may also be available. Access, resources, and formats depend on the supplier account and must be confirmed with Wayfair.
Yes. Martini can integrate with Wayfair by consuming the applicable Wayfair REST APIs, handling supported partner callbacks, and orchestrating approved file or EDI processes. Martini can schedule synchronization, map and validate data, apply business rules, and update downstream systems.
No. A dedicated Wayfair connector is not required. Martini can use Wayfair's confirmed native APIs, supported callbacks, authentication methods, and account-specific file or partner processes.
Lonti does not charge an additional per-connector or per-vendor fee to integrate Wayfair. The integration is subject to the provisioned capacity of the Martini environment. Separate costs may apply from Wayfair, cloud infrastructure, or other third-party systems depending on subscription, usage, and deployment model.
REST APIs are the primary mechanism when they are enabled for the required supplier operation. Selected callbacks, batch or asynchronous exchanges, and file or EDI processes may be used when the account supports them. GraphQL and current SOAP APIs were not confirmed for this scenario.
Broad webhook coverage is not confirmed. Wayfair may provide notifications or callbacks for selected partner processes, but integrations should not assume that every Order, Product, Inventory, Shipment, or Return change is event-driven. Scheduled polling may be required.
Martini can run scheduled workflows that retrieve new or changed objects using pagination and available date or status filters. It maps data into canonical and target models, maintains high-water marks and overlap windows, and stores source identifiers to support idempotent processing and reconciliation.
Martini can classify authentication, throttling, transport, validation, and business-state failures. Transient failures can use bounded exponential backoff, while validation failures are quarantined for correction. Deterministic keys based on order, line-item, shipment, or update identifiers help prevent duplicate downstream transactions.
