Here’s an example of how to handle the webhook:

2import { Webhook } from "svix";
3
4const app = new Hono();
5
6app.post("/webhooks/phonic", async (c) => {
7  if (!process.env.PHONIC_WEBHOOK_SECRET) {
8    return c.text("Bad Request", 400);
9  }
10
11  const wh = new Webhook(process.env.PHONIC_WEBHOOK_SECRET);
12  const rawBody = await c.req.text();
13
14  try {
15    const payload = wh.verify(rawBody, {
16      "svix-id": c.req.header("svix-id") ?? "",
17      "svix-timestamp": c.req.header("svix-timestamp") ?? "",
18      "svix-signature": c.req.header("svix-signature") ?? "",
19    }) as ConversationAnalysisWebhookPayload;
20
21    const { latencies_ms, interruptions_count } = payload.data.conversation;
22    console.log(`Latencies: ${latencies_ms}, Interruptions: ${interruptions_count}`);
23
24    return c.text("OK", 200);
25  } catch (error) {
26    console.error("Failed to verify webhook:", error);
