Full support for ShipStation's V2 API — batch processing, real-time webhooks, and end-to-end order automation across your entire order lifecycle.
Built for high-volume operations
Process hundreds or thousands of orders in a single run. Rate quotes and order updates are batched through ShipStation's V2 API, so large runs finish fast and stay within API rate limits — perfect for scheduled overnight processing or high-volume stores.
Complete order processing pipelines: validate → optimize boxes → apply rules → rate shop → update ShipStation. Run them on a schedule or on demand, with dry-run previews before anything is written and per-order verification after.
ShipStation webhooks trigger your automation the moment new orders arrive. Rules run per-order in real time, and an automatic reconciliation sweep catches anything a missed webhook would leave behind.
Built for high-throughput operations. Batched API calls, asynchronous background processing, and self-pacing rate-limit handling keep large workloads moving without tripping ShipStation's API limits.
Build powerful integrations
Connect your warehouse or ERP system directly. Push orders, pull shipping updates, sync inventory automatically.
Run overnight batch jobs to process all orders. Wake up to optimized, rule-applied orders ready for fulfillment.
Build custom logic on top of ShipExtension. Trigger Slack notifications, update CRMs, or integrate with any system via webhooks.
ShipExtension runs on ShipStation's V2 API — batch processing, real-time webhooks, and end-to-end order automation are all available now.
