02The adapter

A Connectify-owned UPS adapter, not a packaged connector

The runtime takes care of it by keeping the UPS adapter inside our own runtime, monitored by our SRE rotation and updated as United Parcel Service ships breaking changes. That means the field maps, sync cadences, and replay rules are shaped to your exact data model — including UPS Capital insurance + declared value rules and WorldShip parity for batch label generation. 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 UPS usually breaks — and how the adapter holds

The day-to-day pain shows up in multi-channel inventory sync and fee management. Our team closes that gap by mapping every payload through a versioned schema layer with explicit lineage — every record can be traced from the UPS originating event down to the field that wrote it, and the founder gets a real dashboard instead of spreadsheets. The adapter also ships with Rating + Shipping + Address Validation APIs so the runtime can keep up when marketplace seller crews push volume spikes during seasonal peaks.

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

Marketplace Sellers (Amazon, Walmart, eBay) are constantly fighting multi-channel inventory sync and fee management — and UPS sits exactly in the middle of that workflow. Connectify pre-maps the UPS entities the industry actually uses (not the entire vendor catalog) and wires WorldShip parity for batch label generation into the lifecycle that matters: serve-to-renew. That is the difference between a connector that lights up a checkbox and an adapter that so customer service finally sees the same record sales does.

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 UPS 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. Can the UPS adapter handle our custom fields?

    On first connection the adapter discovers every custom field, custom object and custom workflow inside your UPS tenant and presents them as first-class mappings — you decide which to mirror, which to ignore, and which to enrich.

  2. How long does the UPS integration take to ship?

    Our standard window is thirty days from signed scope to live UPS adapter in production, plus a one-week monitored stabilization phase. For Marketplace Sellers (Amazon, Walmart, eBay), that includes a sandbox loop with your team, parallel-run reconciliation, and a documented runbook handed to your operations lead.

  3. Is this a packaged UPS connector or a custom build?

    It is a Connectify-owned adapter, not a third-party packaged connector. We maintain the code, we monitor the runtime, and the fields, hooks, and reconciliation rules are shaped to your exact data model — not a generic schema we hope matches.

  4. What does pricing look like?

    The UPS 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.

  5. What happens if UPS changes their API after we go live?

    Our SRE team monitors UPS 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.

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

    Yes. The Connectify UPS 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.
