VAPI types are wrong for ServerMessageEndOfCallReport

[ian]

The TS type and what actually gets sent are different.

ServerMessageEndOfCallReport.d.ts:

server-sdk-typescript/src/api/types/ServerMessageEndOfCallReport.ts

Line 7 in d6ef2f8

export interface ServerMessageEndOfCallReport {

Actual webhook includes a number of fields not mentioned here:

• transcript
• messages
• summary

and quite a few more. Is there a reason these are left out?

I had claude outline the type differences between what's in the Server SDK and what actually gets sent:

import { Vapi } from "@vapi-ai/server-sdk";

interface CostBreakdown {
  stt: number;
  llm: number;
  tts: number;
  vapi: number;
  chat: number;
  total: number;
  llmPromptTokens: number;
  llmCompletionTokens: number;
  ttsCharacters: number;
  voicemailDetectionCost: number;
  knowledgeBaseCost: number;
  analysisCostBreakdown: {
    summary: number;
    summaryPromptTokens: number;
    summaryCompletionTokens: number;
    structuredData: number;
    structuredDataPromptTokens: number;
    structuredDataCompletionTokens: number;
    successEvaluation: number;
    successEvaluationPromptTokens: number;
    successEvaluationCompletionTokens: number;
  };
}

interface CallMessage {
  role: "system" | "bot" | "user" | "assistant";
  message?: string;
  content?: string;
  time: number;
  endTime?: number;
  secondsFromStart: number;
  duration?: number;
  source?: string;
}

export interface ExtendedServerMessageEndOfCallReport extends Vapi.ServerMessageEndOfCallReport {
  /** Detailed cost breakdown for the call */
  costBreakdown?: CostBreakdown;
  
  /** Duration of the call in milliseconds */
  durationMs?: number;
  
  /** Duration of the call in seconds */
  durationSeconds?: number;
  
  /** Duration of the call in minutes */
  durationMinutes?: number;
  
  /** AI-generated summary of the call */
  summary?: string;
  
  /** Full transcript of the conversation */
  transcript?: string;
  
  /** Array of messages from the conversation */
  messages?: CallMessage[];
  
  /** URL to the mono recording */
  recordingUrl?: string;
  
  /** URL to the stereo recording */
  stereoRecordingUrl?: string;
}

I noticed that some types, like the one you posted, are not exported via index.ts either. Not sure if that's because the type is incomplete, but it would be good to have it added so it can be imported without having to do:

import { ServerMessageEndOfCallReport } from '@vapi-ai/server-sdk/api/types/ServerMessageEndOfCallReport';
