Why teams connect Bigcommerce and IBM AS/400

Give your engineers Bigcommerce's products, orders, and customers in IBM AS/400: read them with normal queries, write inventory and prices back through the sync, and skip the storefront API.

E-commerce data sits behind an API built for the storefront, not for your internal systems. Teams that need those records, for order routing, inventory logic, reporting, or back-office tools, end up writing integration code against a rate-limited API and maintaining it through every catalog change and platform upgrade.

Stacksync mirrors Brands, Inventory, Price Lists, Shipments from Bigcommerce into IBM AS/400 and keeps both sides consistent in real time. Whatever Bigcommerce holds, whether products, orders, customers, or inventory, those records become rows your code can query, and changes written in IBM AS/400, such as new prices, stock levels, or fulfillment status, sync back into Bigcommerce with its validations respected.

Merchandising and operations keep working in the storefront, engineers keep working in the database, and neither side has to reconcile against a nightly export.

Common use cases

  • 01 Keep customer and item files aligned with an ecommerce platform or modern ERP during phased modernization.
  • 02 Feed shipment and invoice data from the AS/400 into logistics and finance tools in near real time.
  • 03 Push Price Lists from an ERP into BigCommerce to drive customer-group and B2B pricing without manual catalog edits.
  • 04 Two-way sync of Products and Variants between BigCommerce and a PIM or ERP so catalog content, SKUs, and pricing stay aligned across systems.

Common sync patterns

Controlled write-back

Choose exactly which tables and fields may flow from IBM AS/400 back into Bigcommerce, keeping the store authoritative on what it owns.

Read the store's data with a query

Records from Bigcommerce, whether products, orders, customers, or inventory, live in IBM AS/400 as ordinary tables or collections, joinable with the rest of your data.

Internal tools and automations without API code

Scripts and services read and write the synced tables; Stacksync handles the Bigcommerce API, rate limits, and retries.

What you can sync between Bigcommerce and IBM AS/400

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.

Bigcommerce objects IBM AS/400 objects How this pairing syncs
Brands Catalog V3 brand records linked to products; kept aligned with a product master or PIM so brand names and pages stay consistent. Physical files (tables) The Db2 for i tables mapped directly to sync targets. Brands is specific to Bigcommerce and Physical files (tables) to IBM AS/400 — each maps to any object or custom field on the other side.
Inventory Product- or variant-level stock, plus multi-location counts via the V3 Inventory API; written from a WMS to reflect on-hand quantities. Logical files (views) Indexed or filtered views over physical files, usable as read sources. Inventory is specific to Bigcommerce and Logical files (views) to IBM AS/400 — each maps to any object or custom field on the other side.
Price Lists V3 price lists and records driving customer-group and B2B pricing; pushed from an ERP so tiered prices stay current. Members Sub-partitions of files in legacy applications, flattened or selected during syncs. Price Lists is specific to Bigcommerce and Members to IBM AS/400 — each maps to any object or custom field on the other side.
Shipments Order shipments with tracking numbers; created in BigCommerce from a 3PL or fulfillment system as packages ship. Rows / records The unit of read and write, accessed via SQL or record-level access. Shipments is specific to Bigcommerce and Rows / records to IBM AS/400 — each maps to any object or custom field on the other side.
Products Catalog V3 records with custom fields and images; mastered in a PIM or ERP and written to BigCommerce, or read out to a warehouse. Journals and journal receivers The change log that enables log-based CDC on journaled files. Products is specific to Bigcommerce and Journals and journal receivers to IBM AS/400 — each maps to any object or custom field on the other side.
Variants and SKUs Per-variant pricing and inventory; synced to keep stock and SKU data aligned with an ERP or WMS at the option level. Data queues Program-to-program messaging objects sometimes used to hand events off to integrations. Variants and SKUs is specific to Bigcommerce and Data queues to IBM AS/400 — each maps to any object or custom field on the other side.

How changes propagate between Bigcommerce and IBM AS/400

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.

Bigcommerce IBM AS/400 Sub-second propagation

DetectionBigcommerce notifies Stacksync of record changes through webhook events. Webhooks push near-real-time events (store/order/*, store/product/*, store/customer/* and more).

DeliveryEach detected change is applied to IBM AS/400 as a row-level write, with types converted between the two schemas.

IBM AS/400 Bigcommerce Sub-second propagation

DetectionChanges in IBM AS/400 are captured at the source via change data capture — no polling loop against its API. Journal-based CDC by reading journal receivers on journaled files.

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

Rate-limit considerations

  • Bigcommerce: OAuth quota refreshes every 30 seconds and varies by plan (about 20,000 requests/hour on Standard and Plus, 60,000 on Pro, higher on Enterprise); the X-Rate-Limit-Requests-Left header reports remaining calls.
  • IBM AS/400: Bounded by system resources and subsystem configuration rather than an API quota.
