What is Document Automation?

Document automation is the process of automatically creating different documents based on a predefined set of rules. It is also known as document assembly or document generation. It comes in handy when dealing with dynamic data in a specific format.

Document automation helps you transform repetitive documents into templates to be reused without being modified programmatically.

Suppose you are creating an ecommerce store for a client. Whenever a customer places an order on the platform, a receipt, usually a downloadable PDF containing the information specific to that order, is generated. We call this process document automation.

How Does Automated Document Generation Work?

In automatic document generation, the system pulls the data and the format from different sources and fills it automatically in predefined document templates. The templates can contain text or graphic elements like tables, images, etc.

It is most used in software solutions where the user needs to assemble complex and dynamic documents frequently. Besides being a time saver for both the developer and the user, it helps the user ensure each document’s accuracy, formatting, and compliance.

How to Automate Document Generation?

Document generation can be automated through coding or innovative solutions available in the market. Let’s explore each in some detail.

Document Generation through Code

Automating document generation through code is possible and is done by various developers worldwide. You must write thousands of lines of code (LOC).

On the one hand, it benefits your skills and understanding as you manually write all the code, enhancing your logic and problem-solving skills.

On the other hand, this approach is more prone to errors and consumes more time than needed. You must debug and test your solution repeatedly whenever you change the code.

Therefore, this is not a recommended approach.

Document Generation through APIs

Using pre-built APIs is an innovative and efficient way of automating document creation. Numerous APIs are available to integrate with your applications and achieve the desired functionality.

These APIs allow you to create document templates through drag and drop as well as through XML, JSON, or other files. Also, you can create different document formats such as docx, pdf, CSV, etc. These APIs enable users to create individual or bulk documents within seconds.

How to Choose the Best Document Generator API?

You can find numerous APIs offering different feature lists for document automation. So, here is a quick guide about the things to consider while choosing a document creation API:


As you might know, in software development, the term “reliability” means the ability of a solution to tackle stressful conditions (measured through load testing). The same goes for the APIs. Whenever you choose a document automation API, you must test it by processing large document files.

Moreover, check if the API offers a guaranteed uptime. Furthermore, test the API for any service interruptions and measure its response rate.


Always check an API’s feature list before spending money on it. Ensure that it contains features you need or may need in the future. An ideal document generation API should have the following features:

  • Multiple document templates.
  • URL and HTML to PDF conversion
  • Drag and drop template editors
  • Bulk document generation


The most important factor of any document generation API is its accuracy. Ensure that the document created by the API matches your template exactly or not. If you see any changes in font styles, sizes, or other elements, never use such API, as it will generate inaccurate future results.

Template Availability

Consider the number of templates an API provides you with. The more the templates, the better.


Security is crucial for your safety, especially in the online world. Before integrating a hosted API solution, consider the following:

  • The API uses a reliable encryption mechanism to protect your data from interceptions while transferring between the API and your application.
  • Check what the API does with your data once it is passed. Whether it deletes it immediately or stores it for some time. An API that deletes the data is the best to use.
  • Ensure the API has specific security certificates such as HIPAA, GDPR, etc. If not, look for an alternative.


Ensure the API is compatible with the programming language or the platform you are working with. Also, consider the integration options and the availability of API for different devices.

Advantages of Automating Document Generation through APIs

If you equip your software solutions with automated document generation processes, you can benefit in the following ways.

Fewer Errors

When writing code, you commit various unnoticeable mistakes that drive you crazy during deployment. By using document generation APIs, you can easily avoid such errors. Moreover, the client gets the authority to customize the templates, so you do not need to change the code each time a new document is created.

Enhanced Efficiency

With APIs, users can create multiple documents simultaneously, increasing the processing speed and saving time. Moreover, customizing the documents is not as tedious as manual document generation. You can drag and drop the fields to be changed through APIs.

Saves Time

As mentioned earlier, APIs save your and your client’s time through automation. Creating new documents or modifying the existing ones does not take much time, thanks to the drag-and-drop facility under APIs.

Easy Data Collection

Collecting data using API calls is relatively easier than sending the documents to different people and asking them to fill them. This helps organizations speed up their processes through dynamic document generation.

Better Compliance

If you are building a solution to be used in an industry where regulations and standards must be followed, using the document generation APIs is the best idea. This will save you from any future conflicts as all the documentation will be managed by your client, and you will not be accountable for any issues.


With automated document generation, each document can be crafted to specific needs while keeping the standardized format intact.


Although implementing a document generation API will require some initial investment, using it can save a lot of your time and energy. Also, your client will not have to spend an amount for each document they need.


Most document generation APIs are cloud-based and ensure data encryption and security using different mechanisms. All the documents and data generated on the user end are kept confidential and secure.

Digital Data Storage

Another benefit of document generator API is that it stores all the data digitally on a cloud or remote server. This negates the need to download, print, or maintain physical copies of the document.
