In this guide, we will add a Novu Bridge Endpoint to a AWS Lambda application and send our first test workflow.

<Steps> <Step> ## Set up your local environment

Start the Local Studio by running:

bash
npx novu dev

The Local Studio will be available at http://localhost:2022. This is where you can preview and test your workflows.

</Step>
<Step> ## Install packages

Install the Novu Framework package:

bash
npm install @novu/framework

This package provides all the necessary tools to build and manage your notification workflows.

</Step>
<Step> ## Add a Novu API Endpoint ```typescript src/functions/api/novu.ts 
    module.exports.novu = serve({
        workflows: [testWorkflow],
    });
    ```
</Step>
<Step>
    ## Configure your secret key

Add your Novu secret key to your environment variables:

bash
NOVU_SECRET_KEY=your_secret_key

</Step>
<Step>
    ## Create your workflow definition
    Add a `novu` folder in your app folder as such `novu/workflows.ts` that will contain your workflow definitions.
ts
import { workflow } from '@novu/framework';

export const testWorkflow = workflow('test-workflow', async ({ step }) => {
  await step.email('test-email', async () => {
    return {
      subject: 'Test Email',
      body: 'This is a test email from Novu Framework!',
    };
  });
});

</Step>
<Step>
    ## Start your application
    Start your AWS Lambda server with the Novu Endpoint configured.

    If your Local Lambda application is running on other than `4000` port, restart the `npx novu dev` command with the port:

    ```tsx
    npx novu@latest dev --port <YOUR_AWS LAMBDA_APPLICATION_PORT>
    ```
</Step>
<Step>
    ## Test your endpoint

Test your workflow by triggering it from the Local Studio or using the Novu API:

bash
curl -X POST https://api.novu.co/v1/events/trigger \
  -H 'Authorization: ApiKey YOUR_API_KEY' \
  -H 'Content-Type: application/json' \
  -d '{
    "name": "my-workflow",
    "to": "subscriber-id",
    "payload": {}
  }'

You should see the notification being processed in your Local Studio.

</Step>
<Step>
    ## Deploy your application

Deploy your application to your preferred hosting provider. Make sure the /api/novu endpoint is accessible from the internet.

For local development and testing, you can use tools like ngrok to expose your local server to the internet.

</Step>
</Steps>

Now that you have your first workflow running, you can:
