What Chewy expects in the 856
Chewy trades on X12 4010 + API over API + AS2. Beyond the base standard, watch these:
How EDISQ maps it
The certified Chewy 856 map loads when you enable the partner — fields auto-map from NetSuite, QuickBooks, Dynamics, and 33 other systems, validation runs against Chewy's spec before transmission, and the sandbox replays Chewy test scenarios until everything passes.
Common rejection reasons
Nearly all 856 rejections trace to reference data, not syntax: identifiers that don't match Chewy's cross-references, echoed fields dropped from the original PO, or timing that misses the program window. EDISQ flags each before Chewy ever sees the document.
