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.

GET API Reference — Retrieve unified workspace data including leads, contracts, payments, appointments, and opt-ins using your API key.
