⚡ Reliability
Best When
Your e-commerce agent needs to automate order fulfillment through a 3PL warehouse network with programmatic inventory and shipment management.
Avoid When
You're just starting out or ship fewer than 200 orders/month — ShipBob's minimums and costs aren't justified at low volume.
Use Cases
- • Agents submitting orders to ShipBob for fulfillment when customers checkout on any sales channel
- • Inventory monitoring — agents checking real-time inventory levels across ShipBob warehouses and triggering restocking
- • Multi-channel order routing — agents sending orders from Shopify, Amazon, and DTC to ShipBob for unified fulfillment
- • Shipment tracking — agents querying ShipBob for tracking numbers and delivery status to update customers
- • Returns management — agents initiating return requests and tracking returned inventory back to warehouses
Not For
- • Small brands not yet outsourcing fulfillment — ShipBob requires minimum volume commitments for new merchants
- • International-only fulfillment — ShipBob is primarily US-focused with limited international warehouse coverage
- • Digital products or services — ShipBob is for physical product fulfillment only
Interface
Authentication
OAuth2 for app integration. Personal access token for direct API access. Scoped OAuth permissions for read-only vs full access. Channel ID required in headers for multi-channel setups.
Pricing
No self-service API pricing — fulfillment pricing is negotiated based on volume and requirements. API access included with active ShipBob account.
Agent Metadata
Known Gotchas
- ⚠ Channel ID header required for multi-merchant setups — missing header returns wrong merchant's data
- ⚠ Order fulfillment is async — submitted orders take 1-3 business days to ship; agents must not expect immediate fulfillment
- ⚠ SKU must be pre-registered in ShipBob inventory — orders with unknown SKUs are rejected
- ⚠ Inventory allocation is eventually consistent — real-time inventory may show available but allocation can still fail
- ⚠ Returns require separate RMA process — agents must create Return objects before marking orders as returned
