# Get a function's current route binding

`GET /functions/{id}/routing`

Returns the endpoint binding for the function, or null when no
route is currently bound. The binding identifies whether the
function receives mail for a specific domain (scoped) or for any
active domain that has no scoped binding (fallback).
