eTailer Integration Service - Parts & Tires (SOAP)
USAF's SOAP API has no catalog-browse endpoint. The only bulk-catalog source is the FTP flat-file feed described in the AIS doc (Tire product master weekly, tire pricing daily, tire/parts inventory every 15 min). Configure USAF_FTP_* credentials in .env, then choose below.
.env (USAF_API_USERNAME, USAF_API_PASSWORD, USAF_ACCOUNT_NUMBER, and USAF_FTP_* for the flat-file feed).
