​
Adding the webhook handler

The webhook handler in this guide will be an API route. Create a new file app/routes/api.webhook-handler.ts or app/routes/api.webhook-handler.js. In your new file, add the following code:
/api/webhook-handler.ts
import type { ActionFunctionArgs } from "@remix-run/node";
import { tasks } from "@trigger.dev/sdk/v3";
import { helloWorldTask } from "src/trigger/example";

export async function action({ request }: ActionFunctionArgs) {
  const payload = await request.json();

  // Trigger the helloWorldTask with the webhook data as the payload
  await tasks.trigger<typeof helloWorldTask>("hello-world", payload);

  return new Response("OK", { status: 200 });
}
This code will handle the webhook payload and trigger the ‘Hello World’ task.

​
Triggering the task locally

Now that you have a webhook handler set up, you can trigger the ‘Hello World’ task from it. We will do this locally using cURL.
1

Run your Remix app and the Trigger.dev dev server

First, run your Remix app.
npm run dev
Then, open up a second terminal window and start the Trigger.dev dev server:
npx trigger.dev@latest dev
2

Trigger the webhook with some dummy data

To send a POST request to your webhook handler, open up a terminal window on your local machine and run the following command:
If http://localhost:5173 isn’t the URL of your locally running Remix app, replace the URL in the below command with that URL instead.
curl -X POST -H "Content-Type: application/json" -d '{"Name": "John Doe", "Age": "87"}' http://localhost:5173/api/webhook-handler
This will send a POST request to your webhook handler, with a JSON payload.
3

Check the task ran successfully

After running the command, you should see a successful dev run and a 200 response in your terminals.If you now go to your Trigger.dev dashboard, you should also see a successful run for the ‘Hello World’ task, with the payload you sent, in this case; {"name": "John Doe", "age": "87"}.
