Vapi Platform Skill

Overview

Vapi is a voice AI platform for building phone agents. Users connect Vapi assistants to Getflowetic to monitor call performance, track costs, and analyze conversation outcomes.

Vocabulary

call: A single voice interaction between an assistant and a caller
assistant: A configured Vapi voice agent with a system prompt, model, and voice
ended_reason: Why the call terminated (hangup, voicemail, error, silence-timeout, max-duration)
cost: Per-call cost in USD based on duration + model usage
transcript: Full text of the conversation
status: Call outcome — ended (success) or other values (failure)

Key Metrics for Dashboards

Call Volume: Total calls over time — trend chart on started_at
Success Rate: Percentage of calls with status=success — hero stat
Avg Duration: Average call length in ms — supporting metric card
Cost per Call: Total cost divided by call count — supporting metric
Assistant Breakdown: Calls per assistant — pie chart on assistant_name/workflow_name

Event Field Mapping

The Vapi import route normalizes call data into the standard event schema. These are the fields that appear in event.state:

Event Field	Semantic Type	Dashboard Use
workflow_id	identifier	Maps to assistant_id — count only
workflow_name	dimension	Maps to assistant name — breakdown charts
execution_id	surrogate_key	Maps to call_id — "Total Calls" KPI
status	dimension	Success rate percentage — hero stat
duration_ms	measure (avg)	"Avg Call Duration" metric card
started_at	time_dimension	Timeseries trend axis
ended_at	time_dimension	Detail only
platform	constant	Always "vapi" — skip

These fields also appear in event.labels:

assistant_id, assistant_name, call_id, status

Dashboard Templates

voice-analytics: Call volume trend, success rate, avg duration, assistant breakdown
assistant-performance: Per-assistant comparison with call counts and durations
cost-tracker: Cost trends over time, cost per call, total spend

Mapping Heuristics (Legacy Aliases)

These field name variations should resolve to the canonical names above:

duration: call_duration_seconds | duration | call_length → duration_ms
status: status | call_status | outcome → status
cost: cost_usd | cost | price → cost
