# Receive an incoming request at a source URL with an explicit event path selector.

`OPTIONS /in/{sourceKey}/{pathKey}`

## Request

- Base URL: `https://api.loopify.com` (the document declares no server; this is the origin it was published from)
- URL: `https://api.loopify.com/in/{sourceKey}/{pathKey}`
- Auth: none declared

If the source also resolves an event from a configured header or payload field, that selector must
agree with pathKey. Webhooks accept JSON only. Form sources also accept form
bodies and handle browser CORS without credentials.
Browser destinations resolve from _redirect, binding configuration, then Referer against the
binding allowlist. Without a safe destination, only generic HTML status text is returned.

## Path parameters

- `sourceKey` string, required
- `pathKey` string, required

## Response `200`

OK
