Common questions
Which carriers support threshold delivery?
2 carriers publish a code for threshold delivery. Freight carried just inside the first doorway and no further.
Is there a standard threshold delivery code across carriers?
No. Each carrier defines its own code, so the same service is spelled differently at every carrier you integrate with — AIT Worldwide Logistics uses TDTHR, Banyan Technology uses THRS. A code is only meaningful together with the carrier it belongs to.
Need this programmatically? /api/accessorials/map?service=threshold returns the same data as JSON on every plan.
