In previous tutorials you've learned about the Blues Notecard, and used it to collect data and send it to Notehub, the Blues cloud service.

One powerful feature of Notehub is routes, which allow you to forward your data from Notehub to a public cloud like AWS, Azure, or Google Cloud, to a data cloud like Snowflake, to dashboarding services like Datacake or Ubidots, or to a custom HTTP or MQTT-based endpoint. The tutorial below guides you through sending data to several popular services, and teaches you how to build visualizations using that data.

*Don't see a cloud or backend that you need? Notehub is able to route data to virtually any provider. If you're having trouble setting up a route, [reach out in our forum](https://discuss.blues.com/) and we will help you out.*

## Introduction

*This tutorial should take approximately 30-40 minutes to complete.*

In this tutorial, you'll learn how to connect your Notecard-powered app to **General HTTP/HTTPS**, and learn how to start creating simple visualizations with sensor data.

This tutorial assumes you've already completed the initial [Sensor Tutorial](https://dev.blues.io/guides-and-tutorials/collecting-sensor-data.md) to capture sensor data, saved it in a [Notefile](https://dev.blues.io/api-reference/glossary.md#notefile) called `sensors.qo`, and sent that data through the Notecard to Notehub (or that you've already created your own app with sensor data and are ready to connect your app to external services).

## Create a Route

A Route is an external API, or server location, where Notes can be forwarded upon receipt.

Routes are defined in Notehub for a [Project](https://dev.blues.io/api-reference/glossary.md#project) and can target Notes from one or more [Fleets](https://dev.blues.io/api-reference/glossary.md#fleet) or all [Devices](https://dev.blues.io/api-reference/glossary.md#device). A Project can have multiple routes defined and active at any one time.

Before you create a Route, ensure the data you want to route is available in Notehub by navigating to the **Events** view:

![events view in notehub](https://dev.blues.io/images/guides/route-tutorial/events-view.png?v=e1b03b17)

In this tutorial you'll create a simple route to an HTTP/HTTPS endpoint. To do this you'll use [webhook.site](https://webhook.site), an online service that lets you create an HTTP endpoint and monitor all incoming requests.

After getting your Notehub route working with webhook.site, switching a route to use a custom endpoint is as easy as switching the URL. Let's see how it works.

1. Navigate to [webhook.site](https://webhook.site). When the page loads, you'll be presented with a unique URL that you can use as a Route destination. Copy that URL for the next step.

   ![webhook.site service](https://dev.blues.io/images/guides/route-tutorial/webhook-site-url.png?v=5ed567fe)

2. Navigate to the [Notehub.io](https://notehub.io) project for which you want to create a route and click on the Routes menu item in the left nav.

3. Click **Create Route**.

   ![create a route button in notehub](https://dev.blues.io/images/guides/route-tutorial/add-route.png?v=4724c860)

4. Select the **General HTTP/HTTPS Request/Response** route type.

   ![general https request route](https://dev.blues.io/images/guides/route-tutorial/general-route.png?v=b3b8e6a5)

5. Give the route a name (for example, "Health").

   ![name notehub route](https://dev.blues.io/images/guides/route-tutorial/route-name.png?v=9aa60fa8)

6. For the Route **URL**, use the unique URL you obtained from webhook.site.

   ![url for notehub route](https://dev.blues.io/images/guides/route-tutorial/route-url.png?v=449917f5)

7. In the **Filters** section, choose **Selected Notefiles** and check the box(es) next to the Notefile(s) you want to route. For example, we used `sensors.qo` for the sensor tutorial.

   ![choose the notefile to sync](https://dev.blues.io/images/guides/route-tutorial/sensors-qo.png?v=b347af44)

8. Make sure the **Enabled** switch at the top remains selected, and click **Create Route**.

9. Only Notes received *after* the Route is created are routed automatically. If new Notes have been received since you created the Route, proceed to the next step.

   Alternatively, you can **manually route** existing Notes by (1) checking the box next to an event, (2) clicking the **Route** button, and (3) choosing the Route you would like to use:

   ![manually route notes](https://dev.blues.io/images/guides/route-tutorial/manual-route.png?v=904af97c)

10. Return to webhook.site. This page will update automatically with data sent from Notehub. The data from your sensor is contained within the `body` attribute. Notice that Notehub provides you with a lot of information, by default. In the next section, we'll look at using transformations to customize what Notehub sends in a Route.

## Use JSONata to Transform JSON

Let's explore how to use JSONata expressions to transform the data Notehub routes.

As mentioned above, Notehub provides a lot of information in each Route request. You may want to trim down what you send to the external service, or you might need to transform the payload to adhere to a format expected by that service. Either way, Notehub supports shaping the data sent to a Route using JSONata.

> **Note:**
>
> To learn more about JSONata later, have a look at the [Blues JSONata Guide](https://dev.blues.io/guides-and-tutorials/notecard-guides/using-jsonata-to-transform-json.md).

### Transform Your Data

Let's try a simple query to the webhook.site Route created in the last section.

1. Navigate to the **Routes** page in Notehub and click on the Route you wish to edit.

   ![view a route](https://dev.blues.io/images/guides/route-tutorial/routes-screen.png?v=0a7ebd91)

2. In the **Transform Data** drop-down, select **JSONata Expression**.

   ![jsonata expression](https://dev.blues.io/images/guides/route-tutorial/jsonata-expression.png?v=98cabc60)

3. In the JSONata Expression text area, add the following query to select the `temp` and `humidity` from the `body`, create a `location` field that concatenates the `tower_location` and `tower_country` fields, and create a `time` field.

   ```json
   {
      "temp": body.temp,
      "humidity": body.humidity,
      "location": tower_location & ', ' & tower_country,
      "time": when
   }
   ```

4. Click **Apply changes**. Then, navigate back to webhook.site. As requests come in, you'll see your custom, JSONata-transformed payload in the Raw Content section.

   ![transformed data routed to webhook.site](https://dev.blues.io/images/guides/route-tutorial/webhook-site-jsonata.png?v=e69aa638)

   > **Note:**
   >
   > The `tower_location` and `tower_country` fields are only populated for events sent over cellular. For Starnote/satellite, LoRa or WiFi devices, those fields will be empty. If you want a single expression that works across connectivity types, use the `best_location` and `best_country` fields instead — Notehub appends those to every event, choosing the most accurate source available (GPS/GNSS, triangulation, or cell tower). See [Data Notehub Appends to Events](https://dev.blues.io/notehub/notehub-walkthrough.md#data-notehub-appends-to-events) to learn more.

JSONata is simple, powerful, and flexible, and will come in handy as you create Routes for your external services. To explore JSONata further, [visit our Blues JSONata Guide](https://dev.blues.io/guides-and-tutorials/notecard-guides/using-jsonata-to-transform-json.md).

## Route to an External Service

Now that you've created your first Route and learned how to use JSONata to shape the data sent by a Route, you can connect Notehub to an external service.

In this case, since you've already created a Route that sends data to webhook.site, all you need to do is update that existing Route's URL to point to your own custom HTTP endpoint.

1. Navigate back to the **Routes** page in Notehub and click on the Route you wish to edit.

   ![view a route](https://dev.blues.io/images/guides/route-tutorial/routes-screen.png?v=0a7ebd91)

2. Update the **URL** to the location of the service or custom endpoint you're using.

   ![Notehub route URL field](https://dev.blues.io/images/guides/route-tutorial/general-http-https/notehub-edit-route-url.png?v=cb68a07b)

> **Note:**
>
> Notehub can route your data to multiple locations simultaneously. As such, it can be handy to keep a webhook.site Route available for debugging.

Depending on your requirements, you might need to further customize the HTTP headers or data transformations of your Route. If you hit any problems getting a Route working, feel free to [reach out in the Blues developer forum](https://discuss.blues.com).

> **Tip:**
>
> To debug a route or inspect the exact request Notehub sends to your third-party service, open an event in Notehub, click **Route as cURL**, and choose the appropriate HTTP-based route. The modal shows a cURL command that reproduces the same request Notehub makes, with secrets (API keys, passwords, etc.) replaced by placeholders.
