Requirements​

• eledo.online account
• Eledo PDF Attachments for WooCommerce plugin

Eledo is an online PDF service allowing you to design PDF templates and create documents with dynamic data. Free accounts are also available. WooCommerce plugin was created to integrate the service with your e-shop. It is open source and free of charge.

Dry run​

Before we spend some time with customization, let's make a dry run.

• Create account at https://eledo.online/register
• Get API Key from Integrations → API page
• Install Eledo PDF Attachments for WooCommerce plugin
• Navigate to WooCommerce → Settings → Eledo PDF and set the API key
• Select public Invoice template and save configuration
• Navigate to WooCommerce → PDF Documents and click Create on some order (manual invoice generation)
• Review created document

What happened?​

You most probably received a PDF invoice for your order, which is not fully populated. Invoice number is not as you expect it, the logo is not yours, and you may not like the colors. Everything can be changed to your satisfaction — keep reading.

Customization

The PDF template we used is a public one and therefore read-only.
To make changes you need to copy it to your personal directory.

1. Click Edit on the public template
2. Click Copy

Now you can modify your own version.

Company details​

Some values are usually included in multiple documents and therefore it is a good idea to define them globally.

There are two types of variables you can define in your Eledo user profile.

Standard properties

Used for text values such as:

• Company name
• Address
• Phone number

Counters

Counters are numeric values that increment automatically.

To populate global variables used by the template:

1. Open the Edit screen
2. Choose Input fields
3. Click Add missing to profile

Missing variables will be added to your profile so you can populate them and save the profile.

Company logo​

The logo can be changed directly in the template editor.

1. Double-click the existing logo
2. Upload your logo in the Upload tab
3. Use Browse Server to select the logo
4. Adjust width and height if necessary
5. Confirm with OK

We strongly recommend using SVG format.

Invoice number generation​

The PDF document identifier (file name) is generated from the expression defined in the File Name field in the template editor.

Example from the public invoice template:

$InvoicePrefix + num(#InvoiceCreated,4)

This produces invoice numbers like:

INV0034

Explanation:

• $InvoicePrefix → user profile variable
• #InvoiceCreated → counter defined in the user profile
• num(N, x) → prints number N padded with leading zeroes to x digits

If we want to derive the invoice number from the order number, the expression could look like this:

$InvoicePrefix + num(id, 4)

To add the year, you can use date functions:

$InvoicePrefix + num(year(), 2) + num(#InvoiceCreated, 4)

Read more in the Expressions guide.

Styling with CSS​

Color, font size or border thickness can be changed using the tools in the template editor, or in a more advanced way using Cascading Style Sheets (CSS).

CSS allows you to change the style of elements globally, for example:

• all tables
• all paragraphs

CSS can be added in the template editor under:

Document → Styles

Email settings and automation​

So far the invoice has been created manually.

Automation comes with email settings. Invoices are generated on demand by an email notification trigger. The invoice is also generated only once per order, even if it is included in multiple email notifications.

Now you need to select which email notifications should include the invoice attachment.

The payment method filter helps you prepare different invoice types per payment method.

For example, you can send a pre-invoice for BACS payments with a QR code to make your customer's payment more comfortable.

Make is a powerful online tool that connects online services and combines them into automated flows with full control. It makes it very easy to automate everyday business tasks.

Documents are usually part of these workflows. They are used for communication between businesses and clients, so they are very important. Every successful business uses personalized and well-designed documents to impress partners or clients.

This is where Eledo becomes useful. It makes document automation and personalization simple for everyone.

Let's Automate Something​

Sign up for Eledo and Make services. This is required because you need to create your own scenario in Make and a document template in Eledo.

Don't worry — both services offer freemium accounts.

In this article we will describe the role of Eledo inside an Make scenario for generating personalized PDF invoices for Shopify orders.

Eledo is also building a public document library that allows you to start quickly with common document types and personalize them later.

Connecting Make and Eledo​

You can find the Eledo PDF Generator module directly in the Make module list. However, to activate it you need to create your personal connection.

Find your API Key in the Eledo dashboard under:

Integrations → API

Create a new connection in Make and paste your API Key.

Keep this key private and do not share it with others, otherwise they could use your quota or templates. You can generate a new API Key anytime if needed.

Press Continue to validate and save the connection.

Next, choose a document template. If you haven't created one yet, you can use a public template for testing.

We provide a ready-to-use Invoice for Shopify template for quick setup.

Data Mapping​

Eledo automatically prepares the web form and API structure for your document template.

Once your template is saved and activated, you can immediately load the new fields in Make and start mapping your data to generate the PDF.

Invoices are complex documents with many values to transfer, so mapping takes some time to configure properly.

Templates often include line items, which makes this scenario a good example of how Make and Eledo can handle structured data together.

Here Comes the PDF​

The output from the Eledo module is a binary PDF file that you can use however you like.

Document generation happens on the fly, and transaction data is not stored in the Eledo cloud by default, because we respect your privacy.

What can you do with the generated document?

You can:

• save it to a file storage
• attach it to an email
• upload it to another service

With Make, there are practically no limits.

For example, uploading to Google Drive is very simple.

The file name is defined in the Eledo template, and it can be dynamic.

Eledo also supports document counters, allowing you to generate unique document numbers automatically.

Sending the document as an email attachment works in a similar way.

Notice how the file name is used in the email subject.

In this example, the invoice file name looks like:

A simple way to print the line items table would be to create a table with many rows and populate only some of them. Unfortunately, tables with empty rows do not look good and preparing such templates takes unnecessary time.

Eledo provides an elegant solution that is simple, powerful, and prints the exact number of rows needed.

Eledo Template​

Insert a table with two rows and multiple columns.

Populate the first row with table headers.

Move the cursor to the second row and click Block Repetition.

The selected block will initially be Table Cell. Since we want to repeat the entire row, click Select parent Block to change it.

Then populate the Data expression with:

line_items

Confirm the configuration with OK.

The row will become yellow, indicating it is a repeating block.

Now insert Text Boxes into the row.

Place the cursor in the first cell and click Table Box. Populate the Data expressions with line item fields and confirm. Repeat the process for each column.

The last column usually contains the line total, which we can calculate directly in the Eledo template.

A simple expression could be:

Quantity * Price

However, totals are usually rounded and formatted with two decimal places, so we recommend using:

CURR(ROUND(Quantity * Price, 2), 0, 2)

Save the template and your automation is ready.

Make scenario​

Our Eledo template with the line items array should look like this:

There are several ways to populate the array.

The most intuitive way might seem to be Add item and manually populate the column values. However, this is not the correct approach.

If we want a dynamic number of rows, we must use the Map toggle and populate line_items with an array.

There are two main approaches.

Easy way​

The simplest method is to pass the entire source array directly into line_items.

This works if the source array structure matches the structure expected by the Eledo template.

If the structures do not match, you may see missing values in the generated PDF.

In that case, you can adjust the field names in the Eledo template so they match your source array structure.

This method works best if you plan your template structure in advance.

Advanced configuration​

For more advanced scenarios — such as mapping between arrays or combining multiple data sources — a second method can be used.

This method provides more control but consumes more Make operations.

It typically consists of:

• an Iterator or Repeater module
• an Array Aggregator

The Iterator processes your source array.

The key configuration happens in the Array Aggregator:

1. Select Iterator as the Source Module
2. Choose Eledo line items as the Target Structure
3. Map the fields into the structure expected by your Eledo template

Finally, populate the line_items field in the Eledo module using the array produced by the Aggregator.

Your dynamic line items are now fully configured.

Eledo makes this possible in an easy and automated way. In this article we will show you how to integrate Eledo PDF document automation into your monday.com Board.

Adding Eledo into your monday.com Board​

You can find the Eledo App in the monday.com Marketplace or simply click the button below.

In both cases you will need to authorize the Eledo App to access your board by clicking the Authorize button.

This authorization allows Eledo to:

• read your board data and insert them into your PDF document
• write the generated document back to your board
• read assets when image attachments are included

Setting up your Eledo PDF template​

With Eledo you can create a custom PDF document, or upload a PDF form that you want to fill automatically.

In both cases you need to write data expressions that tell Eledo which information from your monday.com board should appear in the document.

Data expressions can consist of:

• field names
• functions
• operations that modify the values

To make this easier, you can connect your Eledo template with your monday.com Board, and the expression builder will help you create the correct expressions.

To connect them you will need to know your Board ID.

You can find instructions here:

Where to find board item and column IDs

Then navigate to Input Fields in the Eledo template editor, enter your monday.com Board ID, and click Import.

Field names from your board will appear below as Imported Fields, including your custom columns.

The expression builder will then provide suggestions for fields that can be used in your template.

Don't forget to re-import fields whenever you change columns in your board so the template structure stays up to date.

Setting up monday.com Integration Recipes​

Once your document template is ready, you are only one step away from automation.

Choosing when the document should be generated is important.

Typically you want the document to be created when:

• task information is complete
• the task needs to be processed further
• the document should be stored as a PDF record

Generating the same document multiple times for one task can unnecessarily consume your Eledo subscription limits, so configure your Recipes carefully.

You can find Eledo integration recipes directly in your monday.com board.

Click the Integrate button and search for Eledo.

We have prepared multiple recipes.

After selecting a recipe you will need to complete the sentence configuration.

Click the underscored words to configure the recipe parameters. Once everything is set up, the PDF will be generated automatically according to your configuration.

Done! Your automated document creation is now set up.

Error Handling​

If everything seems configured but you are not receiving your PDF, the issue is usually related to the Eledo template configuration.

Eledo records every PDF generation request as an event and creates a log entry for it.

Each log contains:

• date and time
• event source
• template used
• document statistics such as page count and generation time

Important: Eledo does not record transactional data (the actual request content).

Logs may also include:

• warnings
• errors

These messages can help identify problems with your request.

You can access the logs in Eledo and inspect the event log details.

Helpdesk​

If something is not working as expected, feel free to contact the Eledo Helpdesk.

We hope this automation saves you time and improves your workflow. We would also be happy to hear your feedback.

Open Eledo Feedback Form

With Eledo, you can now achieve this in an effective and automated way. In this article we will show how to easily integrate Eledo into your Zapier workflows (Zaps).

Adding Eledo into Zapier​

Keep in mind that the Zapier integration is currently in closed beta. This means it will not appear in the Zapier public directory yet and you will need an invitation link to access it.

Follow Zapier invitation

Accept the invite and start building your Zaps with Eledo.

Setting Up Your Eledo PDF Template​

With Eledo you can:

• create custom PDF documents
• upload PDF forms that should be automatically filled

In both cases you need to define data expressions. These expressions tell Eledo which information from other applications should appear in the generated document.

Data expressions usually consist of:

• field names
• functions
• operations that modify values

In the following example we demonstrate how to prepare a template in Eledo and connect it with Zapier.

Let's imagine we want to generate a PDF product sheet from Shopify containing attributes such as:

• product name
• price
• quantity
• weight

With Eledo automation, these values can automatically appear in the generated PDF whenever a new product is created in Shopify.

Creating the Template​

The first step is creating a PDF template in Eledo using text boxes that represent data expressions.

Simply enter the attribute name that should appear in your document.

For example, if you want the product price to appear in the document, insert a text box with the corresponding attribute name.

Repeat this process for all attributes you want to include in your document.

In our example we include:

• product name
• price
• quantity
• weight

The final template may look like this:

Building the Zap​

Once your template is ready, you can start building your Zap in Zapier.

1. Choose a Trigger​

Select the application where your data originates.

In this example:

• Application: Shopify
• Trigger event: New Product

2. Create the Document with Eledo​

Add an Eledo action step to generate the PDF.

In the Set up action section:

• choose the template you created in Eledo
• in this example we use Shopify Product

3. Map Template Fields​

Now connect your template fields with the data coming from Shopify.

In this example we map:

• name
• price
• quantity
• weight

The final mapping configuration should look like this:

4. Send the Generated PDF​

Finally, choose the application where you want to store or send the generated document.

In this example we use Google Drive.

When configuring the step, make sure to populate:

• File
• File Name

using the PDF generated by the Eledo step.

Example configuration:

Once the Zap runs, the generated PDF will automatically appear in your Google Drive.

Error Handling​

If you configured everything but the PDF is not generated, the issue is often related to the Eledo template configuration.

Eledo records every PDF generation request as an event and stores a log entry.

Each log includes:

• date and time
• event source
• template used
• statistics such as page count and generation time

Important: Eledo does not record transactional data (the actual content of the request).

Logs may also contain warnings and errors that help identify the issue.

You can view these logs in the Eledo dashboard.

Helpdesk​

If something is not working as expected, feel free to contact the Eledo Helpdesk.

We hope this automation will save you a lot of time. We will also appreciate your feedback.

At first you should have some data store of your orders to provide ongoing automation digital data in a good shape. Then you need some template for your label, ideally customizable. Thanks to modern integration tools it should be easy to build a bridge between your order source and a label generator.

As Eledo is a document generation service, let's find out how you can use it.

1. Shipping Labels for WooCommerce​

WooCommerce is a popular e-commerce platform and it's also open source, which helped us prepare a native plugin for integration. You can download it from the WordPress public plugin directory or from our webpage. Once installed, a quick configuration gets it working.

The public document "Shipping Labels for WooCommerce" was created for this purpose. It has a basic structure and is designed for A5 size.

Because we are talking about automation, 4 labels are placed on an A4 paper sheet so you can print them in bulk and then cut them to size.

Navigate to the PDF Documents section, where you can select multiple orders and execute a bulk PDF generation operation from the Action menu. When you receive the PDF, print it as usual.

If you are not happy with the label design, don't worry. Our service makes it possible to personalize the document template. From simple font size or color changes to more advanced styling techniques via CSS.

Feel free to add a logo or decoration image anywhere to make your labels more distinctive. Copy the public document and be creative.

2. Automation with Zapier​

Zapier is an online tool that connects your favorite apps and automates repetitive tasks without coding or relying on developers to build integrations. Our service is integrated with Zapier as well, so you can take advantage of these capabilities.

An interesting implementation can be found in their blog article. It describes how to print labels automatically every time, without needing to click anything.

The workflow collects labels into a queue and prints them once four labels have been gathered.

3. Your Own Implementation​

We provide a PDF generation service with basic document templates. You can customize the template, but you can also use the REST API to generate your document programmatically.

Find more details about the API in the documentation and implement your own solution.

Barcodes​

The public document also contains a barcode at the bottom.

To make it work you need to provide a valid value from your data source. You can also:

• replace it with a QR code
• use another type of code
• remove it completely if you do not need it

There are many libraries and tools to render or convert documents, but sometimes even developers run into trouble when using them.

That's why Eledo was born. It provides a fast and easy way to prepare PDF templates with dynamic elements for developers and non-technical users alike. Let's explore its advantages.

Template is all you need​

Thanks to generative design patterns, all you need to prepare is the template. Everything else happens automatically.

You can immediately generate your PDF either by:

• filling in a web form
• using the REST API

The rich-text in-browser editor is portable and available online.

Besides paragraphs, lists, tables, or images, it includes custom components that help define dynamic parts of the template.

Some examples include:

• text fields
• conditional blocks
• repetitive blocks

These allow you to design more advanced document scenarios.

Other useful components include:

• barcodes
• QR codes
• digital signature placeholders

For those who want even more power, there are expressions.

Expressions allow you to:

• split dynamic data
• combine values
• perform mathematical operations
• aggregate vector data
• use boolean logic in conditional blocks

No more wasted time (and money)​

Designing templates from scratch can be time-consuming, so we are building a public library of common templates.

You can simply:

1. copy a template
2. modify it
3. adapt it to your needs

Our mission is to save your time while giving you maximum flexibility.

You can also save time when integrating Eledo into your solutions. We provide plugins for platforms like:

• WooCommerce

We also support integration platforms such as:

• Zapier
• RapidAPI

Time is money — and money is time.
It just depends on which one you have more of.
