Some sellers are onboarded to FedEx through the FedEx Integration Channel rather than directly. Huup supports that route as its own provider, with the validation and error handling that path needs.
Huup ships FedEx through a FedEx Integration Channel account, with its own validation and error mapping, for sellers onboarded that way rather than direct.
If your FedEx account came through an integrator rather than direct, the direct API path does not apply. This is the provider that matches how you were set up.
FIC shipments are validated against their own rules rather than being pushed through the direct FedEx validator, which is what avoids confusing rejections.
For the warehouse nothing changes. It appears in the same dispatch screen, batch and tracking timeline as every other carrier.
Everything below runs against your own carrier account. Huup creates the shipment and prints the label; it does not resell postage.
Shipments are created through the FIC channel and the label comes back to the dispatch screen like any other carrier.
A dedicated validator checks the shipment against what this channel accepts before submission.
Tracking events are mapped into the shared timeline, so support does not need to know which FedEx route was used.
Errors coming back from the integrator are mapped separately from direct FedEx errors so the cause is not misread.
You keep the account and the rates you negotiated. Huup uses them to create shipments and print labels.
