Bring Vendor Intelligence Into Existing Systems

Event builder on the left · delivery inspector on the right. Compose vendor intelligence events and inspect signed payloads before wiring ERP, Slack, or data warehouse listeners.

Event builder · 6 event types

Test only — Send Test Event fires a temporary webhook. It does not write a formal Vendor Record, and the test delivery auto-deletes after 24 hours.

Send Test Event posts to your webhook URL with X-VendorMist-Signature — inspect delivery status in the right pane.
