Developer Surfaces

Hermon exposes two external-facing developer surfaces:

Outbound Webhooks — Hermon POSTs events to your registered server endpoint when things happen in the platform (contract signed, payment received, appointment booked, etc.). Your server must return a 2xx status to acknowledge receipt.

Opt-In Submit API — You POST lead data to Hermon from your own forms, funnels, or landing pages using an API key. Supports UTM tracking, Q&A answers, idempotency, and setter attribution.
