API reference
REST + Python SDK reference for the OmniDimension platform with an interactive try-it-out playground.
The OmniDimension API lets you create agents, dispatch calls, manage phone numbers, and pull call analytics from your own systems. Auth is a single Bearer API key on every request.
Every endpoint is interactive
Open any endpoint below and you will find a live playground. Paste your API key under Authorization, fill in the request, and hit ▶ Run to see the real response without leaving the docs. Your key is held in this browser session only — it's wiped on reload.
