02The adapter

A Connectify-owned BigCommerce adapter, not a packaged connector

The runtime takes care of it by keeping the BigCommerce adapter inside our own runtime, monitored by our SRE rotation and updated as BigCommerce ships breaking changes. That means the field maps, sync cadences, and replay rules are shaped to your exact data model — including Stencil theme sync for hybrid storefronts and Channel routing for marketplace + social storefronts. For marketplace sellers, the difference shows up the first time the upstream API throws a 500 — the adapter retries, journals the failure, and never silently swallows a transaction.

Where BigCommerce usually breaks — and how the adapter holds

The day-to-day pain shows up in multi-channel inventory sync and fee management. The platform handles that by mapping every payload through a versioned schema layer with explicit lineage — every record can be traced from the BigCommerce originating event down to the field that wrote it, so the warehouse team stops chasing emails. The adapter also ships with Order events tied to Connectify Finance posts so the runtime can keep up when marketplace seller crews push volume spikes during seasonal peaks.

Why Marketplace Sellers (Amazon, Walmart, eBay) pull BigCommerce integration the hardest

Marketplace Sellers (Amazon, Walmart, eBay) are constantly fighting multi-channel inventory sync and fee management — and BigCommerce sits exactly in the middle of that workflow. Connectify pre-maps the BigCommerce entities the industry actually uses (not the entire vendor catalog) and wires Stencil theme sync for hybrid storefronts into the lifecycle that matters: lead-to-revenue. That is the difference between a connector that lights up a checkbox and an adapter that so the warehouse team stops chasing emails.

Commercial terms — one flat monthly plan, no setup fee

Connectify charges a monthly retainer sized to your message volume — no per-API-call gotchas, no per-seat surcharges, and no setup fee to get started. The BigCommerce adapter goes live only after it is reconciled and signed off by the team that will operate it inside the marketplace seller workflow. A one-page exit clause hands you the code if you ever leave, so Connectify keeps the adapter working under load to keep your business.

Frequently Asked Questions

  1. What does pricing look like?

    The BigCommerce adapter runs on a flat monthly retainer sized to message volume — no per-API-call gotchas, no per-seat surcharges, no setup fee, and a one-page exit clause.

  2. Do we own the integration code at the end?

    Yes. The Connectify BigCommerce adapter ships with full source escrow rights — at any point you can request a snapshot of the code, configuration, and runbooks. We prefer you stay on our managed runtime, but you are never locked in.

  3. What happens if BigCommerce changes their API after we go live?

    Our SRE team monitors BigCommerce change announcements and rolls compatibility updates inside our maintenance retainer. If a breaking change ships, we own the migration; you don't pay extra to stay current and you don't field calls from the vendor.

  4. Will this break our existing reports?

    No. The adapter writes through a versioned schema layer with full lineage. Existing reports, BI extracts and Excel pivot-tables keep working unchanged while new fields and new objects are added behind the scenes for the BigCommerce surface.

  5. Does it work with our existing BigCommerce licenses?

    Yes — the adapter rides on top of your existing BigCommerce subscription. We use service-principal or OAuth M2M credentials so the integration never burns a named-user seat and never pushes you into a higher tier.

  6. How is data security handled?

    Tokens and credentials live inside a hardware-backed secret store with audit logging on every read. The BigCommerce adapter runs on isolated workers with deny-by-default egress, and every message is replayable from a tamper-evident journal for downstream forensics.
