Actions must be HTTP Post or Get operations.

Use @post or @get for actions; model other HTTP verbs as normal resource operations instead.

Impact

Section titled “Impact”
  • Area: API, SDK

A resource action that does not use POST or GET produces an improper HTTP API and can break the C# SDK and emitters that model resource actions (service, portal).
