Function postTiltifyTestDonations

postTiltifyTestDonations(params: PostTiltifyTestDonationsParams): Promise<void>
Fire a synthetic Tiltify donation (or batch) through the Play Live core REST API, which replays it down the same webhook path a real donation takes — alerts, donation trains, subathon timer, and every WebSocket subscriber all react as if Tiltify had delivered it.

Intended for overlay QA: drive an alert without waiting on a real donor. Reads its base URL from twitchServiceUrl (the core REST API — same host that serves the Twitch charity proxy routes).

Auth: supply adminApiKey or tiltifyOAuthToken. Donations that target a demo campaign need neither.
Parameters
- params: PostTiltifyTestDonationsParams
  PostTiltifyTestDonationsParams.
Returns Promise<void>
Resolves once the service has accepted the payload.
Throws
Error when twitchServiceUrl is not configured, or when the response is non-2xx (401 on bad/missing credentials).
