snapcasterChoose your path
Both Integration paths start the same way. Your Platform pushes a Seller’s Listings, and Snapcaster hosts buyer Browse, Checkout, and payment. The path decides who fulfils the resulting Order.
| Path A: Snapcaster-managed | Path B: Partner-managed | |
|---|---|---|
| Who fulfils | The Seller in the Snapcaster dashboard | Your Platform in its own system |
| What the Platform receives | inventory.adjusted deltas | order.created and lifecycle events |
| Buyer PII | None | Name, email, and shipping address |
| Subscription | inventory | orders, or both |
| Typical fit | A POS or inventory backend | An order-fulfilment backend |
Choose Path A when your system owns On-hand counts but does not model or fulfil Orders. Choose Path B when your system receives and fulfils Orders.
The both Subscription
Section titled “The both Subscription”both is a Path B variant.
Your Platform receives the complete order.created work order and the inventory.adjusted Inventory adjustment.
Deduct On-hand from exactly one source, or the sale will be counted twice.
Shared onboarding
Section titled “Shared onboarding”Snapcaster sets the Platform Subscription during onboarding. Each Seller then generates a Marketplace API key and gives it to your Platform. The per-Platform Signing secret is exchanged separately for outbound webhook verification.
Continue to Credentials and sandbox before running the Golden path.
