Introduction to BigCommerce
BigCommerce is a SaaS eCommerce platform built for merchants who want a hosted, scalable storefront without sacrificing flexibility or performance.
Focused on mid-market and enterprise merchants, including B2C and B2B businesses that want to minimize technical debt and overhead while maximizing flexibility.
Popular with brands that want enterprise-grade features without the maintenance time and costs of a self-hosted platform.
Connecting BigCommerce to iPaaS.com keeps product, order, customer, and inventory data synchronized with your ERP, fulfillment, and marketing systems in real time.
API Version Support
iPaaS.com uses methods from the BigCommerce REST Admin API (both v3 and v2) and the BigCommerce B2B Edition API:
v3: catalog data (products, variants, options, categories, brands, and inventory), customers, and payments.
v2: orders and related order data, gift certificates, and customer groups.
B2B Edition API: company, company user, and B2B payment features (available on version 1.4 and greater).

Versions and Release Notes
Version | Release Notes |
1.4 (current) | B2B Edition support — companies, company users, customer groups and price lists (with bulk pricing), sales-representative assignment, and company status, payments, and addresses — plus product custom fields and metafields, multi-channel category support, product URL redirects, extended product-image functions, and alternate-unit fulfillment. Hardening across the 1.4 series: BigCommerce's partial-success (HTTP 207) responses are handled so an inventory update no longer fails silently; order reads are cached to prevent rate errors and slowness on large orders; payment duplicate-detection matches by code; shipment external IDs and the order/shipment polling order are corrected; quantity-1 stocking-unit price rules are handled correctly; and null-reference guards were added across the transfer paths. Every error the integration can record now carries a stable, searchable code with a subscriber-facing message, cause, and resolution (see the Error Messages article). |
1.3 | Expanded catalog, order, and customer capabilities: product modifiers, alternate units of measure, product option-value overrides, channel assignments, related products, customer attribute and address-formatting formulas, validated returns, add-only inventory transfers, and order and line-item discounts. |
1.2 | Initial release: core synchronization of products (options, option values, and variants), orders (line items, addresses, taxes, discounts, and payments), customers and their addresses, inventory, payment methods, and gift cards. |
The current shipping version is 1.4.2.
