# Quickstart

> Register your endpoint and receive your first Spark360 webhook event.

Use this guide to create a webhook subscription and validate a successful delivery.

## 1) Add an HTTPS endpoint

Register an endpoint URL that begins with `https://`.

<Warning>
  Non-HTTPS endpoints are rejected at create and edit time.
</Warning>

## 2) Choose event types

Available events:

* `lead.address_preview`
* `lead.enriched`
* `lead.rental_alert`
* `lead.contact_requested`
* `widget.status_changed`

<Note>
  `lead.enriched` is required and always included.
</Note>

## 3) Save and copy the signing secret

When a subscription is created, Spark360 generates a signing secret and stores it in Supabase Vault. The secret is displayed once at creation time.

## 4) Trigger a test event

Use the Test Endpoint action in Settings to send a sample `lead.enriched` payload and inspect:

* HTTP response code
* Response body
* Signature header

## 5) Verify lead payload defaults

All lead payloads include:

```json theme={null}
{
  "source_tracking": {
    "widget_version": "01",
    "widget_name": "Primary",
    "source_code": "01",
    "source_label": "Website"
  }
}
```
