# Get the org's function routing topology

`GET /functions/routing-topology`

Returns a single snapshot of how inbound mail is routed across
this org's active domains and functions: which active domain has
which function bound, the org's fallback function (if any), and
every deployed function with no route bound. Use this to answer
"which of my functions actually receive mail?" diagnostically.
