PATCH
Pause, resume, or retune (cadence, cap, webhook)

Authorization
string
header
required

fn_live_… or fn_test_… — Authorization: Bearer

Headers

fn-version
string

Dated API version; defaults to the account pin. Honesty note: with one version in existence the gateway echoes any value back as effective WITHOUT validating it — validation against the known-versions set is planned, so send only real dated versions from https://docs.fiveninelabs.com/changelog

Example:

"2026-08-26"
