What we solve

What DropStream solves for marketplace integrations.

Marketplace integrations break in predictable ways. Listings drift, ASNs miss windows, inventory falls out of sync. DropStream is the platform layer that keeps every channel honest, so your team isn't chasing chargebacks at 11pm.

Get Started
01

Channel sprawl without engineering tax

Add Amazon, Walmart, TikTok Shop, Wayfair without staffing a marketplace integrations team.

02

Inventory drift across channels

One source of truth. Inventory updates broadcast to every connected marketplace within seconds.

03

EDI & API in the same flow

Walmart DSV, Wayfair Castlegate, Target+ — EDI 856 / 940 / 945 alongside REST, in one connector.

04

Chargebacks before they happen

Real-time monitoring catches missed ASNs, late shipments, and spec rejections before deductions hit.

How it works

Your marketplace orders automatically flow.

DropStream connects your marketplaces to your fulfillment systems and keeps order, inventory, and tracking data in sync.

Workflow diagram: marketplaces feed orders down into DropStream, which routes to WMS, 3PL, ERP, and carriers; inventory and tracking flow back up to the marketplaces

What flows in

Orders, order updates, cancellations, and returns from every connected marketplace including Amazon, Walmart, TikTok Shop, eBay, and more

What flows back

Shipment confirmations, tracking numbers, and inventory levels sync back to the marketplace so listings stay accurate and SLAs stay green

What gets mapped

DropStream's rules engine translates marketplace data into the formats your WMS, 3PL, or ERP expects — SKU mapping, address formatting, shipping method translation, and channel-specific business rules

What we monitor

Every sync, every marketplace, every minute. If something breaks — a rate limit, a data mismatch, a marketplace API outage — DropStream alerts you before your customer notices

FAQ

The questions teams ask about marketplace integrations.

Walmart DSV and Wayfair Castlegate are usually the hardest because they layer EDI on top of API. DropStream owns both the EDI side (856 / 940 / 945) and the API side, so the merchant sees one connector and one source of truth instead of two parallel pipelines.
Pre-built marketplaces are typically live in 3–10 business days end-to-end, including credentials, mapping, and a test order cycle. Custom connectors are scoped at days — not quarters.
DropStream owns the connector. API changes, deprecations, and version bumps are handled by our platform team — your engineers don't touch it. We've shipped through Amazon SP-API migration, Walmart's marketplace consolidation, and TikTok Shop's quarterly schema changes without a single customer-facing outage.
No. DropStream is the integration platform underneath channel managers, WMSes, and ERPs. You can run with or without a channel manager — many DropStream customers use Zentail or ChannelAdvisor for listings/pricing and DropStream for the order, inventory, and fulfillment data flow.
