# Workflow 2: Generating reports

In this workflow, you will merge data from different sources, transform binary data, generate files, and send notifications about them. The final workflow should look like this:

<figure><img src="/_images/courses/level-two/chapter-five/workflow2.png" alt="Workflow 2 for aggregating data and generating files" style="width:100%"><figcaption align = "center"><i>Workflow 2 for aggregating data and generating files</i></figcaption></figure>

To make things easier, let's split the workflow into three parts.

## Part 1: Getting data from different sources

The first part of the workflow consists of five nodes:

<figure><img src="/_images/courses/level-two/chapter-five/workflow2_1.png" alt="Workflow 1: Getting data from different sources" style="width:100%"><figcaption align = "center"><i>Workflow 1: Getting data from different sources</i></figcaption></figure>

1. Use the [**HTTP Request node**](/integrations/builtin/core-nodes/n8n-nodes-base.httprequest/index.md) to get data from the API endpoint that stores company data. Configure the following node parameters:

    - **Method**: Get
    - **URL**: The **Dataset URL** you received in the email when you signed up for this course.
    - **Authentication**: Generic Credential Type
        - **Generic Auth Type**: Header Auth
        - **Credentials for Header Auth**: The Header Auth name and Header Auth value you received in the email when you signed up for this course.
    - **Send Headers**: Toggle to true
        - **Specify Headers**: Select `Using Fields Below`
        - **Name**: `unique_id`
        - **Value**: The unique ID you received in the email when you signed up for this course.

2. Use the [**Airtable node**](/integrations/builtin/app-nodes/n8n-nodes-base.airtable/index.md) to list data from the `customers` table (where you updated the fields `region` and `subregion`).
3. Use the [**Merge node**](/integrations/builtin/core-nodes/n8n-nodes-base.merge.md) to merge data from the Airtable and HTTP Request node, based on matching the input fields for `customerID`.
4. Use the [**Sort node**](/integrations/builtin/core-nodes/n8n-nodes-base.sort.md) to sort data by `orderPrice` in descending order.

/// question | Quiz questions
* What's the name of the employee assigned to customer 1?
* What's the order status of customer 2?
* What's the highest order price?
///

## Part 2: Generating file for regional sales

The second part of the workflow consists of four nodes:

<figure><img src="/_images/courses/level-two/chapter-five/workflow2_2.png" alt="Workflow 2: Generating file for regional sales" style="width:100%"><figcaption align = "center"><i>Workflow 2: Generating file for regional sales</i></figcaption></figure>

1. Use the [**If node**](/integrations/builtin/core-nodes/n8n-nodes-base.if.md) to filter to only display orders from the region `Americas`.
2. Use the [**Convert to File**](/integrations/builtin/core-nodes/n8n-nodes-base.converttofile.md) to transform the incoming data from JSON to binary format. Convert each item to a separate file. (Bonus points if you can figure out how to name each report based on the orderID!)
3. Use the [**Gmail node**](/integrations/builtin/app-nodes/n8n-nodes-base.gmail/index.md) (or another email node) to send the files using email to an address you have access to. Note that you need to add an attachment with the data property.
4. Use the [**Discord node**](/integrations/builtin/app-nodes/n8n-nodes-base.discord/index.md) to send a message in the n8n Discord channel `#course-level-two`. In the node, configure the following parameters:
    * **Webhook URL**: The Discord URL you received in the email when you signed up for this course.
    * **Text**: "I sent the file using email with the label ID `{label ID}`. My ID: " followed by the unique ID emailed to you when you registered for this course. <br/> Note that you need to replace the text in curly braces `{}` with [expressions](/glossary.md#expression-n8n) that reference the data from the nodes.

/// question | Quiz questions
* How many orders are assigned to the `Americas` region?
* What's the total price of the orders in the `Americas` region?
* How many items does the **Write Binary File node** return?
///

## Part 3: Generating files for total sales

The third part of the workflow consists of five nodes:

<figure><img src="/_images/courses/level-two/chapter-five/workflow2_3.png" alt="Workflow 3: Generating files for total sales" style="width:100%"><figcaption align = "center"><i>Workflow 3: Generating files for total sales</i></figcaption></figure>

1. Use the [**Loop Over Items node**](/integrations/builtin/core-nodes/n8n-nodes-base.splitinbatches.md) to split data from the Item Lists node into batches of 5.
2. Use the [**Set node**](/integrations/builtin/core-nodes/n8n-nodes-base.set.md) to set four values, referenced with expressions from the previous node: `customerEmail`, `customerRegion`, `customerSince`, and `orderPrice`.
3. Use the [**Date & Time node**](/integrations/builtin/core-nodes/n8n-nodes-base.datetime.md) to change the date format of the field `customerSince` to the format MM/DD/YYYY.
    - Set the **Include Input Fields** option to keep all the data together.
4. Use the [**Convert to File node**](/integrations/builtin/core-nodes/n8n-nodes-base.converttofile.md) to create a CSV spreadsheet with the file name set as the expression: `{{$runIndex > 0 ? 'file_low_orders':'file_high_orders'}}`.
5. Use the [**Discord node**](/integrations/builtin/app-nodes/n8n-nodes-base.discord/index.md) to send a message in the n8n Discord channel `#course-level-two`. In the node, configure the following parameters:
    * **Webhook URL**: The Discord URL you received in the email when you signed up for this course.
    * **Text**: "I created the spreadsheet `{file name}`. My ID:" followed by the unique ID emailed to you when you registered for this course. <br/> Note that you need to replace `{file name}` with an expression that references data from the previous **Convert to File node**.<br/>

/// question | Quiz questions
* What's the lowest order price in the first batch of items?
* What's the formatted date of customer 7?
* How many items does the **Convert to File node** return?
///
