Why teams connect Channelengine and Plex ERP

Keep the storefront in step with the back office: Channelengine and Plex ERP share products, inventory, and orders in real time, in both directions.

Channelengine runs the storefront and takes the orders; Plex ERP 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 Backorders, Order documents, Orders, Products (product content) in Channelengine with Parts, Inventory, Production jobs, Sales orders in Plex ERP field by field, in real time, and in both directions. You decide which system owns which fields — stock and pricing from Plex ERP, order and customer detail from Channelengine — and Stacksync keeps every copy consistent and resolves conflicts by rules you set.

Common use cases

  • 01 Write Shipments with tracking back to ChannelEngine when the warehouse or ERP marks an order shipped, so each marketplace notifies the buyer.
  • 02 Sync Returns and Cancellations two-way so customer-service and finance systems reconcile marketplace returns and cancellations with the ERP.
  • 03 Push sales orders captured in e-commerce or EDI systems into Plex for scheduling and fulfillment.
  • 04 Mirror purchase orders and receipts to accounting or planning tools.

Common sync patterns

New orders reach the back office

An order captured in Channelengine creates the matching record in Plex ERP with customer, line items, and totals, so fulfillment and invoicing start without re-entry.

One product catalog

Where both systems keep item records, SKUs, descriptions, and attributes stay aligned so the store and the back office describe the same product.

Fulfillment and shipment status close the loop

As orders are picked, shipped, or invoiced in Plex ERP, tracking and status flow back to Channelengine so buyers see accurate updates.

What you can sync between Channelengine and Plex ERP

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.

Channelengine objects Plex ERP objects How this pairing syncs
Shipments Fulfillment records; write with POST /v2/shipments to mark an order shipped with tracking, read with GET /v2/shipments. Pushed back from a warehouse or ERP so marketplaces update the buyer. Shipments Outbound logistics records synced to trading partners and tracking systems Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Order documents Invoices and other order documents; retrieved as a paginated, filterable list via GET /v2/orders/documents for finance and archiving systems. Read-only. Production jobs Shop-floor work records combining ERP and MES data for output reporting Order documents is specific to Channelengine and Production jobs to Plex ERP — each maps to any object or custom field on the other side.
Orders Marketplace and merchant-fulfilled orders; read via GET /v2/orders and GET /v2/orders/new (status NEW), then acknowledged with POST /v2/orders/acknowledge so later shipment, return, and cancellation calls can reference them. Sales orders Demand records written in from e-commerce or EDI channels and read out for fulfillment status Orders is specific to Channelengine and Sales orders to Plex ERP — each maps to any object or custom field on the other side.
Products (product content) Catalog records created and updated via POST /v2/products and deactivated via DELETE; use a parent/child variant model where the parent is a non-purchasable blueprint. Written into ChannelEngine from a PIM, ERP, or database. Purchase orders Procurement records mirrored to accounting and planning systems Products (product content) is specific to Channelengine and Purchase orders to Plex ERP — each maps to any object or custom field on the other side.
Offers (price and stock) Price and stock updates via PUT /v2/offer/stock and the offers endpoints; separate from product content so fast-changing stock can be pushed often, and supports bulk updates across stock locations. Customers Account records kept consistent with the sales team's CRM Offers (price and stock) is specific to Channelengine and Customers to Plex ERP — each maps to any object or custom field on the other side.
Returns Marketplace- and merchant-initiated returns; read via GET /v2/returns and created with POST /v2/returns. Synced two-way so customer-service and finance systems reconcile with the ERP. Suppliers Vendor records aligned with procurement and AP tools Returns is specific to Channelengine and Suppliers to Plex ERP — each maps to any object or custom field on the other side.

How changes propagate between Channelengine and Plex ERP

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

Channelengine Plex ERP Sub-second propagation

DetectionChannelengine notifies Stacksync of record changes through webhook events. Webhooks fire on order creation and on return and shipment/cancellation changes.

DeliveryEach detected change is written to Plex ERP through its API, with automatic retries and rate-limit backoff.

Plex ERP Channelengine Interval-based propagation

DetectionStacksync polls Plex ERP for changes on an incremental schedule, reading only records changed since the previous pass. Polling.

DeliveryEach detected change is written to Channelengine through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Channelengine: Rate limits are per endpoint and returned in headers: x-rate-limit-limit (interval length in minutes), x-rate-limit-remaining, and retry-after (seconds to wait); e.g. POST /v2/supportorder allows 3 calls per minute.
  • Plex ERP: Subject to the platform's API rate limits.

How the Channelengine and Plex ERP connectors work

Channelengine

Integration surface
REST API (Merchant API v2); per-tenant base URL https://{tenant}.channelengine.net/api
Authentication
API key passed as the 'apikey' parameter; ChannelEngine recommends sending it in a request header rather than the URL because some webservers log full URLs
Change detection
Webhooks fire on order creation and on return and shipment/cancellation changes; product content and offers use change-tracking endpoints (GET /v2/products/data and /v2/products/offers) with an acknowledge pattern that returns only changed records, plus polling GET /v2/orders/new
Capabilities
read · write · webhooks
Rate limits
Rate limits are per endpoint and returned in headers: x-rate-limit-limit (interval length in minutes), x-rate-limit-remaining, and retry-after (seconds to wait); e.g. POST /v2/supportorder allows 3 calls per minute.

Plex ERP

Integration surface
REST APIs plus legacy SOAP web services
