# Testing Guide

> Test delivery, signature verification, retries, and failure behavior.

Use the tools and scenarios below to validate Spark360 webhook behavior end to end.

## Recommended tools

| Tool         | URL                                            | Best for                                                   |
| ------------ | ---------------------------------------------- | ---------------------------------------------------------- |
| webhook.site | [https://webhook.site](https://webhook.site)   | Quick ad-hoc HTTPS endpoint and live request inspection    |
| Pipedream    | [https://pipedream.com](https://pipedream.com) | Persistent endpoint and forced 4xx/5xx response simulation |

## Core scenarios

| Scenario             | How to test                           | Expected result                                         |
| -------------------- | ------------------------------------- | ------------------------------------------------------- |
| Successful delivery  | Use webhook.site and trigger a lead   | `status = delivered` with correct headers/signature     |
| HMAC verification    | Recompute signature using your secret | Signature validates                                     |
| 4xx abandonment      | Return 403 from endpoint              | Immediate `abandoned`, no retries                       |
| 5xx retry sequence   | Return 500 from endpoint              | Retries, warning on attempt 4, abandonment on attempt 5 |
| Required core event  | Configure optional events only        | `lead.enriched` still fires                             |
| Rental co-fire       | Trigger non-owner-occupied lead       | `lead.enriched` and `lead.rental_alert` both deliver    |
| Test Endpoint button | Run test from Settings UI             | Sample `lead.enriched` delivered with inline response   |

## Source tracking fallback values to verify

For lead events, verify:

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