About the BigCommerce integration

BigCommerce is a SaaS commerce platform for mid-market and B2B merchants with multi-storefront and headless options. The Unify Orders API reads its orders, products, variants, customers, shipments and inventory.

BigCommerce offers REST and GraphQL APIs with OAuth 2.0 for apps and webhooks for orders, products and inventory. The Unify Orders API maps orders, products, variants, customers, shipments, refunds and inventory by location to the Unify Graph.

Why build BigCommerce on Unify Int

  • One data model

    BigCommerce records arrive in the same Unify Graph shape as every other platform in the category, with the original record kept in raw.

  • Unify Connect

    A white-label flow for your customers to authorize BigCommerce. Tokens are stored and refreshed for you.

  • Custom fields and passthrough

    Map BigCommerce custom fields per connection, and call any endpoint the model does not cover through passthrough requests.

  • Unify Monitor

    Request logs, sync health and alerts for every BigCommerce connection, so support can see what happened.

BigCommerce integration questions

Does Unify Int support BigCommerce orders and products?
BigCommerce is on the Unify Int roadmap. The planned scope covers reading orders, products, variants, customers, fulfillments, refunds, inventory levels and payouts, with write-back for products, variants and fulfillments to follow. Request it to move it up, or ask the Technology Center about a custom build.
How do customers connect their BigCommerce account?
Your customer installs your app in BigCommerce through Unify Connect and approves the OAuth 2.0 scopes.
Is there a BigCommerce sandbox for testing?
Yes. BigCommerce provides sandbox stores to partners for development.
How often does BigCommerce data sync?
Unify Sync uses BigCommerce webhooks for change detection, so new and updated records usually arrive within minutes, with scheduled polling as a safety net. You can set the schedule per object.
Can I access BigCommerce custom fields?
Yes. Product custom fields and metafields can be mapped into the model per connection.
