Linking a carrier account
NexudeIT supports two ways of doing this:
Direct credentials — paste the API key, account number, and (where applicable) meter number issued by your carrier. We store them encrypted and use them to call the carrier's rate API directly. Available now: USPS, UPS, FedEx, DHL, Canada Post, Royal Mail
Aggregator relay (recommended) — when the platform has EasyPost (or Shippo) configured, you can register your existing UPS / FedEx / USPS / DHL account through them in one step. EasyPost handles the per-carrier OAuth dance, label printing, and tracking webhooks. You pay EasyPost's flat per-shipment fee directly out of your EasyPost wallet — NexudeIT does not intermediate billing.
You don't have to link anything. Sellers who don't link a carrier just configure flat / weight-based methods, paste tracking numbers manually, and skip the rest.
