Cancel a run

End a run.

End a run. A call it asked for and not yet dialled is cancelled; a call in progress is never cut.

Rate limit: 2000 requests per minute per organization, counted together with every endpoint that has no stricter limit of its own. Exceeding it returns 429 with Retry-After; the X-RateLimit-* response headers report your remaining allowance on every call.
