​
X-CEKURA-API-KEY
string
header
required

API Key Authentication. It should be included in the header of each request.

Body

Widget configuration. Key rules:

  • line / pie: set field only (e.g. "duration", "call_ended_reason"). No aggregation needed.
  • bar: set field + aggregation_function (e.g. "count") + time_period (e.g. "day").
  • stat: leave field empty — returns total_calls, success_rate, avg_duration, p95_latency.
  • field = "metric_evaluations.value": metric (integer metric ID) is required. Get valid IDs from GET /test_framework/v1/metrics?agent_id=<id>.
  • effective_filters (read-only): merged dashboard + widget filters — useful for debugging.
