Use a different sender depending on which Specter warehouse the shipment comes from.
Each row connects:
a Specter Warehouse, and
a Sender Key.
Good to know
The Sender Key must match a key you have set up under Senders exactly.
The warehouse is typed as free text, because Junipeer can't fetch the list from Specter. Type each value exactly as Specter sends it – same spelling and same upper/lower case. A value that doesn't match is skipped without an error, and the default is used instead.
This is an advanced setting.
