Why teams connect Easypost and TikTok Shop

Keep the storefront in step with the back office: Easypost and TikTok Shop share products, inventory, and orders in real time, in both directions.

Easypost runs the storefront and takes the orders; TikTok Shop owns the item master, the stock on hand, and the finance behind every transaction. The two overlap wherever the same products, customers, and sales matter to both — and when re-keying or an overnight batch is what connects them, the store oversells items it can't ship, quotes prices finance never set, or leaves buyers waiting on status that already changed.

Stacksync syncs Shipment, Address, Parcel, Rate in Easypost with Shops, Products, SKUs, Orders in TikTok Shop field by field, in real time, and in both directions. You decide which system owns which fields — stock and pricing from TikTok Shop, order and customer detail from Easypost — and Stacksync keeps every copy consistent and resolves conflicts by rules you set.

Common use cases

  • 01 Verify and normalize customer Addresses through EasyPost before they are saved to the CRM or OMS to cut failed deliveries and carrier address-correction surcharges.
  • 02 Sync CarrierAccount configuration and negotiated rates so shipping options stay consistent across the storefront, ERP, and 3PL systems.
  • 03 Sync product catalogs and pricing from a PIM or ERP into shop listings
  • 04 Write tracking numbers and fulfillment status back to TikTok Shop when orders ship

Common sync patterns

Fulfillment and shipment status close the loop

As orders are picked, shipped, or invoiced in TikTok Shop, tracking and status flow back to Easypost so buyers see accurate updates.

One customer master

Where both systems keep customer records, a correction in either propagates to the other, ending dual maintenance.

Where TikTok Shop is the inventory system of record: stock stays accurate

Available quantities from TikTok Shop publish to Easypost, so the store shows what can actually ship and stops overselling.

What you can sync between Easypost and TikTok Shop

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

Easypost objects TikTok Shop objects How this pairing syncs
CarrierAccount Carrier credentials and settings that control which carriers and negotiated rates are available; create, update, and delete to manage enabled carriers across accounts. Promotions Discount campaigns that affect order pricing and settlement reconciliation. CarrierAccount is specific to Easypost and Promotions to TikTok Shop — each maps to any object or custom field on the other side.
Webhook Event subscriptions delivering an Event via HTTP POST on object changes; full CRUD (create, retrieve, list, update, delete) and the mechanism for near-real-time change delivery to Stacksync. Shops The seller storefront; API access is authorized and scoped per shop. Webhook is specific to Easypost and Shops to TikTok Shop — each maps to any object or custom field on the other side.
Shipment The central writable object: create with a to/from Address and Parcel, receive Rate options, then buy a label to get postage_label and tracking_code; retrieve and list with cursor pagination. Products Listings synced from a PIM or ERP catalog, subject to platform review. Shipment is specific to Easypost and Products to TikTok Shop — each maps to any object or custom field on the other side.
Address Origin and destination locations; create, retrieve, and list, plus address verification (delivery and residential) to normalize and validate addresses before they are saved downstream. SKUs The purchasable variants under a product; inventory and price live at this level. Address is specific to Easypost and SKUs to TikTok Shop — each maps to any object or custom field on the other side.
Parcel Package dimensions and weight (or a predefined_package); created standalone or inline on a Shipment and reused across shipments and batches. Orders Purchases pulled into an OMS or ERP for fulfillment and accounting. Parcel is specific to Easypost and Orders to TikTok Shop — each maps to any object or custom field on the other side.
Rate Carrier service and price options EasyPost generates on a Shipment; read-only - you select a rate id and buy it, you do not create or edit rates directly. Fulfillment packages Shipment units where tracking numbers and carrier data are written back. Rate is specific to Easypost and Fulfillment packages to TikTok Shop — each maps to any object or custom field on the other side.
