Session tester
Start a two-party session on your own account via
POST /v1/accounts/{sid}/sessions. Pick a connection type per
leg, tweak the generated playbook if you like, and go. WebRTC legs get an
invite link anyone can open in a browser. Calls are real and billable.
Account
Account auth token (Basic) or an API key starting with vxk_ (Bearer — needs the sessions:write scope). Stored only in this browser's localStorage.
Legs
Playbook
Regenerated when you change the legs above. Edit it to take over — your version is then sent verbatim.
Participants
These states are a creation-time snapshot for routing the join links —
live lifecycle events go to the playbook's
callbackUrl
(point it at e.g. webhook.site to watch them). For WebRTC legs, the join
page shows its own live connection state.
