# Receive an incoming request at a source URL without an explicit event path selector.

`POST /in/{sourceKey}`

## 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}`
- Auth: none declared

Use this route with an event header or payload routing field. Missing selectors are retained as unmatched,
including on single-event sources. Webhooks accept JSON;
form sources also accept form-encoded bodies and _event selectors. Browser CORS applies only to
form sources. Source-configured webhook authentication is enforced for POST requests.
JSON Content-Type or Accept: application/json retains JSON 202/200/4xx responses. Browser forms
use an allowlisted redirect or a minimal status page; rejected redirects include loopify_error.
