Triggering tasks with webhooks in Remix

Prerequisites

• A Remix project, set up with Trigger.dev
• cURL installed on your local machine. This will be used to send a POST request to your webhook handler.

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:

import type { ActionFunctionArgs } from "@remix-run/node";
import { tasks } from "@trigger.dev/sdk";
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.

First, run your Remix app.

```bash npm
npm run dev
```

```bash pnpm
pnpm run dev
```

```bash yarn
yarn dev
```

Then, open up a second terminal window and start the Trigger.dev dev server:

```bash npm
npx trigger.dev@latest dev
```

```bash pnpm
pnpm dlx trigger.dev@latest dev
```

```bash yarn
yarn dlx trigger.dev@latest dev
```

To send a POST request to your webhook handler, open up a terminal window on your local machine and run the following command:

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.

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"}.
