02The adapter

A Connectify-owned USPS adapter, not a packaged connector

The platform handles that by keeping the USPS adapter inside our own runtime, monitored by our SRE rotation and updated as United States Postal Service ships breaking changes. That means the field maps, sync cadences, and replay rules are shaped to your exact data model — including Tracking event ingestion into Connectify Support and Tracking event ingestion into Connectify Support. For online fashion brands, 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 USPS usually breaks — and how the adapter holds

The friction surface that matters is returns rate and size-chart accuracy. The platform handles that by mapping every payload through a versioned schema layer with explicit lineage — every record can be traced from the USPS originating event down to the field that wrote it, so the warehouse team stops chasing emails. The adapter also ships with Domestic + International form generation (CN22, CP72) so the runtime can keep up when online fashion brand crews push volume spikes during seasonal peaks.

Why Online Fashion Brands pull USPS integration the hardest

Online Fashion Brands are constantly fighting returns rate and size-chart accuracy — and USPS sits exactly in the middle of that workflow. Connectify pre-maps the USPS entities the industry actually uses (not the entire vendor catalog) and wires Domestic + International form generation (CN22, CP72) into the lifecycle that matters: procure-to-pay. 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 USPS adapter goes live only after it is reconciled and signed off by the team that will operate it inside the online fashion brand workflow. A one-page exit clause hands you the code if you ever leave, so Connectify keeps the adapter working on month-end close to keep your business.

05FAQ

Frequently Asked Questions

  1. Is this a packaged USPS 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.

  2. What does pricing look like?

    The USPS 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.

  3. Can the USPS adapter handle our custom fields?

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

  4. How is data security handled?

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

  5. Does it work with our existing USPS licenses?

    Yes — the adapter rides on top of your existing USPS 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. What happens if USPS changes their API after we go live?

    Our SRE team monitors USPS 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.
