# Webhooks

> Onedrive incoming webhooks: event paths, payloads, and response data.

The Onedrive plugin handles incoming webhooks. Point your provider’s subscription URL at your Corsair HTTP handler (see [Overview](/plugins/onedrive/overview) for setup context and the exact URL shape).

<Info>
  **New to Corsair?** See [webhooks](/concepts/webhooks) and [hooks](/concepts/hooks).

## Webhook map

* `drive`
  * `driveNotification` (`drive.driveNotification`)
  * `validation` (`drive.validation`)

## HTTP handler setup

import { processWebhook } from "corsair";
import { corsair } from "@/server/corsair";

export async function POST(request: Request) {
    const headers = Object.fromEntries(request.headers);
    const body = await request.json();
    const result = await processWebhook(corsair, headers, body);
    return result.response;
