Architecture Overview

What is eBay EDI Integration?

eBay EDI Integration automatically converts retail purchase orders into native eBay Order records through the REST API — no re-keying, no spreadsheets. When your team fulfills, native webhooks fire the 856 ASN back to partners like Walmart and Target, and the 810 invoice follows shipment. The 846 keeps inventory levels synchronized so you never sell stock you cannot ship.

Operational Blueprint Active Sync

Zero-Touch EDI Reliability for eBay

  • Every inbound 850 passes schema and business-rule validation before it becomes a native eBay Order.

  • Webhook events keep eBay inventory and fulfillment status synchronized with every trading partner in real time.

  • Documents move over encrypted AS2, SFTP, or VAN connections with 997 acknowledgment tracking on every exchange.

Raw EDI in. Posted eBay Orders out.

Partner 850s land on the Cogential gateway over AS2, SFTP, or VAN and clear X12 syntax checks, 997 acknowledgment handling, and partner-specific map validation before translation. The mapping engine resolves every PO1 line against your eBay InventoryItem records by Variant SKU or Barcode ID, applying pack-size multipliers and price checks in flight. Validated orders post through eBay's REST and GraphQL endpoints as native Order records, keyed on seller-defined external identifiers so every write is idempotent. Outbound, eBay webhooks — fulfillments/create, orders/fulfilled, inventory_levels/update — fire on real fulfillment and inventory state changes, assembling 856, 810, and 846 documents from actual Shipment and InventoryItem data inside partner compliance windows.

ENGINEERING SPECIFICATION

Bidirectional Pipeline & Native Architecture for eBay

Whiteboard-level breakdown of document intake, field defaults, cross-reference mapping, and runtime handshake constraints.

INBOUND PIPELINE
EDI 850 eBay Order

A Walmart or Target purchase order arrives over AS2, SFTP, or VAN, clears X12 syntax and map validation against your eBay InventoryItem catalog, and posts as a native eBay Order through the REST and GraphQL APIs with no human re-entry. Buyer-initiated 860 change requests update the Order only while it remains unfulfilled; once a Fulfillment Order exists, changes divert to an exception queue instead of overwriting shipped lines.

Runtime Field Defaults

ERP Field Assignment Rule Failure Prevented
Default eBay Location (Locations & Fulfillment Services) When the N1*ST loop carries a store or DC code with no mapped eBay Location, the Order is assigned to a preconfigured default Location and held before Fulfillment Services are invoked. Prevents orders from stalling without a fulfillment service assignment or shipping from the wrong warehouse node.
Order Status & Fulfillment Hold Flag Incoming 850 Orders are created unfulfilled with a fulfillment hold until inventory allocation and buyer payment verification clear. Ensures stock allocation and payment checks complete before a Fulfillment Order is created and tracking is promised to the buyer.
Fallback Buyer & Seller Account Entity N1*BY buying-party identifiers resolve through the cross-reference table to the correct eBay seller account and buyer record; unmatched partners post under a designated fallback account with an exception flag. Prevents high-volume retail orders from posting to unknown buyer accounts or the wrong selling entity.

Data Cross-Reference & Resolution

Mapping Type Source EDI → Target ERP Resolution Logic
Item SKU & Part Number Translation
Partner UPC/GTIN (PO1-06 'UP', PO1-07 value) or Vendor Part # (PO1-06 'VN') eBay InventoryItem Variant SKU & Barcode ID
Resolves retailer UPCs to eBay variant SKUs through the InventoryItem barcode identifier, expanding multi-variation listings to the correct child variant before the Order posts.
Ship-To Store & DC Location Mapping
Partner N1*ST Store or Distribution Center Identification Code eBay Location & Fulfillment Services Assignment
Translates Walmart, Target, and Home Depot DC codes directly into the correct eBay Location so Fulfillment Services ship from the designated node.
Unit of Measure (UOM) Multiplier
Retailer Ordering UOM (e.g., Case 'CA', Inner Pack 'IP') eBay InventoryItem Base Stocking UOM (Each 'EA')
Applies automatic pack-size multipliers so case-ordered lines deduct the correct Each-level quantities from InventoryItem tracking.

Pre-Translation Validation Guards

Duplicate PO Guard Action on Failure: Diverts the duplicate PO to an exception queue with an alert, preventing double fulfillment.

Fingerprints partner ID plus PO number — a repeated Walmart or Home Depot 850, for example — and queries eBay for existing open and closed Order records before posting.

Price & Allowance Tolerance Match Action on Failure: Flags price discrepancies outside the agreed tolerance before committing the Order, preventing downstream invoice deductions.

Compares EDI line pricing against the seller's contracted partner cost and the live eBay offer price for the resolved variant.

Cancel-After Date Enforcement Action on Failure: Prevents allocating stock to orders that would arrive past the retailer's strict receiving window and incur chargebacks.

Validates the PO delivery window against current fulfillment lead times at the assigned eBay Location.

OUTBOUND PIPELINE
eBay fulfillments/create, orders/fulfilled Webhooks EDI 856 (ASN) & EDI 810 (Invoice)

When a Fulfillment Order is marked shipped, eBay's fulfillments/create and orders/fulfilled webhooks fire, and Cogential assembles the 856 ASN from the real Shipment record — carton-level SSCC-18s, carrier SCAC, and GS1-128 label data — transmitting to Walmart inside its one-hour ASN arrival window. Order completion releases the 810 invoice with SAC allowance and charge detail, while inventory_levels/update events drive 846 Inventory Advice so partners such as Costco and Lowe's always see current stock.

Fulfillment & Packaging Defaults

Parameter Fallback Rule Failure Prevented
Carrier SCAC & Routing Defaults When the eBay Fulfillment or Shipment record carries no explicit carrier assignment, a preconfigured default SCAC — UPSN for ground parcels, for example — is stamped onto the 856. Retailer receiving portals reject ASNs that have missing or invalid SCAC codes.
GS1-128 SSCC-18 Barcode Structure Your GS1 company prefix is applied to generate 18-digit SSCC-18 serial shipping container codes for every carton in the 856 packaging loop, and the same identifiers print on GS1-128 labels and packaging slips. Guarantees globally unique carton tracking numbers for automated scanning at retail distribution centers.

Outbound Normalization & Codes

Mapping Type Source ERP → Target EDI Resolution Logic
ERP Shipping Method to Carrier SCAC
eBay Fulfillment Shipment Carrier & Service Fields Trading Partner SCAC (e.g., UPSN, FDEG, ODFL)
Maps the carrier and service level captured on the eBay Shipment to the formal four-character SCAC each partner's routing guide requires.
Tax & Allowance Charge Codes
eBay Order & Shipment Freight, Discount, and Fee Details EDI SAC Segment Codes
Translates freight surcharges, promotional discounts, and marketplace fees into standardized SAC allowance and charge codes on the 810.

Outbound Dispatch & Timing Guards

Pick/Pack Quantity Reconciliation Action on Failure: Holds ASN generation until the discrepancy is resolved, preventing retailer receiving chargebacks.

Ensures shipped quantities on the eBay Fulfillment match physical carton scans and never exceed the original 850 line quantities.

Advance Shipment Timing Guard Action on Failure: Dispatches a high-priority alert if the ASN has not transmitted within the required partner delivery window.

Verifies the 856 transmits and receives a 997 acknowledgment before the carrier arrives at the partner DC — Walmart's one-hour ASN window being the tightest.

NATIVE HANDSHAKE & CONCURRENCY PROFILE
Reliability metrics engineered for eBay's native interface
ERP Protocol & Interface

eBay REST and GraphQL APIs for all reads and writes, with native webhooks (fulfillments/create, orders/fulfilled, inventory_levels/update) driving outbound event triggers.

Authentication & Tokens

OAuth 2.0 with Bearer access tokens, refreshed on eBay's token lifecycle so long-running integrations never post with expired credentials.

Concurrency & Rate Limits

A rate-aware scheduler queues and micro-batches REST/GraphQL calls against eBay's API call rate quotas, spreading bursts across the window so live seller sessions and dashboards are never throttled or locked.

Idempotent Error Recovery

Dropped connections retry idempotently against eBay Order and InventoryItem records using seller-defined external identifiers, unrecoverable faults park in an exception queue for reprocessing, and versioned REST APIs mean each release is validated in sandbox before cutover.

eBay ACROSS SUPPLY CHAIN SECTORS

Tailored Integration Workflows for Your Industry

Discover how businesses in distinct sectors use eBay EDI to meet stringent partner compliance mandates.

Sector Flow

E-commerce

Marketplace sellers face constant pressure to keep inventory accurate across channels while retail partners demand 846 updates on their own schedule. We sync eBay InventoryItem levels bidirectionally, so every channel and partner DC sees the same stock picture.

Sector Flow

Retail

Retailers like Walmart and Target enforce strict ASN and labeling windows, and every miss becomes a chargeback. We trigger the 856 from eBay fulfillment webhooks the moment goods ship, keeping every shipment inside the compliance window.

Sector Flow

Consumer Goods

Consumer goods suppliers run high SKU counts with promotional pricing that shifts mid-cycle. Price and quantity tolerances are validated against the 850 before the 810 posts, so deductions never surprise you at month end.

Sector Flow

Textiles & Apparel

Apparel lives on size-color variant structures, and one mis-mapped child SKU can poison an entire purchase order. Every variant resolves to the correct eBay InventoryItem before order intake, with exceptions quarantined for review.

Sector Flow

Furniture & Home Goods

Furniture orders ship heavy, split across multiple cartons, and often drop-ship from different Locations. We generate multi-carton 856 ASNs and route lines by Fulfillment Service, so big-ticket orders leave any warehouse compliant.

eBay INTEGRATION HURDLES

Where do eBay EDI connections usually break down in production?

Most EDI failures occur when business rules, custom ERP fields, and trading partner validation are not aligned in real time.

01
Retail partners send 860 PO change requests after picking has started — and eBay API quotas throttle reprocessing during peak season. How do orders stay accurate?

Each 860 re-validates against the original 850 and updates the eBay Order with line-level deltas flagged for your team. Asynchronous queues pace the API calls within quota, so even a peak-day burst of changes processes in sequence without loss.

02
Can the 856 ASN reach Walmart and Target inside their ship window when fulfillment happens across multiple eBay Locations?

Yes — native fulfillments/create and orders/fulfilled webhooks fire the moment a shipment is recorded, triggering ASN generation without polling delays. The 856 transmits with carton and tracking detail inside the partner's compliance window, which is what keeps chargebacks off your deduction reports.

03
How do we stop unit price mismatches between the 850 and our listings from becoming invoice disputes?

Every 810 is three-way matched against the original PO and shipped quantities before it transmits, with price and quantity tolerances enforced automatically. Variances quarantine with an alert, so your team resolves the exception instead of absorbing a deduction.
