Notes

Slybroadcast API delivery times are interpreted in Eastern Time and use 24-hour format (YYYY-MM-DD HH:MM:SS).
Use one audio source per campaign request: account recording title, system audio file, public URL, local file, or AI text.
Local and AI-generated files are staged first and must be publicly reachable for Slybroadcast to fetch.
