Example usage

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

import { Hono } from "hono";
import { Webhook } from "svix";
const app = new Hono();
app.post("/webhooks/phonic", async (c) => {
  if (!process.env.PHONIC_WEBHOOK_SECRET) {
    return c.text("Bad Request", 400);
  }
  const wh = new Webhook(process.env.PHONIC_WEBHOOK_SECRET);
  const rawBody = await c.req.text();
  try {
    const payload = wh.verify(rawBody, {
      "svix-id": c.req.header("svix-id") ?? "",
      "svix-timestamp": c.req.header("svix-timestamp") ?? "",
      "svix-signature": c.req.header("svix-signature") ?? "",
    }) as ConversationTransferredWebhookPayload;
    const { conversation, transferred_to } = payload.data;
    console.log(`Conversation ${conversation.id} transferred to ${transferred_to}`);
    return c.text("OK", 200);
  } catch (error) {
    console.error("Failed to verify webhook:", error);
    return c.text("Bad Request", 400);
  }
});
export default app;
