# Introduction

> Goliath's webhook API — send data in, get signals out.

Goliath connects your systems to real-world property signals through two types of webhooks.

**Inbound webhooks** let external systems push contact data into Goliath — from dialers, CRMs, Airtable, Zapier, or anything that can send a POST request. No user session required.

**Outbound webhooks** let Goliath push enriched property and contact data to your systems when a catalyst signal fires — pre-probate, foreclosure, tax delinquency, and more.

## Inbound webhooks

Push contact data into Goliath from any external system using a token-authenticated URL. Supports AI extraction from unstructured text, structured creates, contact lookup, and contact updates.

## Outbound webhooks

Receive enriched property events from Goliath when a configured catalyst signal is detected. Each payload includes property metrics, parcel data, ownership info, and skip trace results.
