What we solve
What DropStream solves for marketplace integrations.
Marketplace integrations need reliable performance in order to meet the strict marketplace fulfillment requirements. If shipments are late, merchants can get punished by the marketplace. DropStream is the platform layer that knows the marketplace requirements, and is designed to keep your orders and shipments flowing.

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.
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 flows back
Shipment confirmations, tracking numbers, and inventory levels sync back to the marketplace so listings stay accurate and SLAs stay on track.
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.
AI Commerce
You can't predict the next AI commerce channel. You can be ready for it.
The next channel your customers buy from may not exist yet. AI shopping agents and AI-driven discovery, from ChatGPT Shopping to Amazon Rufus, are quickly becoming shopping channels, and every new surface is one more order format that can break when it lands in systems that weren't built for it.
DropStream routes every order to your fulfillment systems no matter where it originates, whether a marketplace, an AI shopping agent, or a channel that doesn't exist yet. DropStream isn't an AI solution. It's the flexibility to adopt one the moment it matters, without rebuilding your stack. Whatever AI commerce becomes, your orders keep flowing.

FAQ
The questions teams ask about marketplace integrations.
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.
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.
Yes. When an AI shopping agent completes a checkout on behalf of your customer, that order flows through DropStream to your fulfillment systems exactly like a human-placed order. DropStream handles the routing, mapping, and monitoring.
Yes. DropStream provides pre-built integrations for TikTok Shop, Instagram Shop, and other social and emerging channels, routing their orders into your WMS, ERP, or 3PL the same way it handles Amazon or Walmart. For 3PLs, that means you can take on a merchant's TikTok Shop volume without a custom build or a separate API project.
