API Documentation

You can use the free Sandbox Account for 3 months to evaluate and integrate the API. The Sandbox Account allows you to make 2500 merges per month.

Whether you need to create invoices, packing slips, contracts or labels, PDF Generator API helps you easily create the document templates and generate polished documents with the data you already have available. You can even allow your users to modify their templates without any development effort!

Users can edit and manage their templates

We provide a workspace logic that allows creating a separate workspace for each of your user where they can edit and manage their templates. A new workspace is automatically created whenever you make API requests with a new workspace identifier.

Allow your users to modify templates

You can embed the template editor into your application to allow your users to modify their own templates. It is possible to display the editor in a new window/tab or in an iframe.

Share templates with your users

You can set up default templates that can be used as base templates by your users. Whenever they modify a default template a new copy is saved to their workspace.

Powerful Expression language

You can write mathematical and logical expressions to manipulate and customize values displayed in components. Use ternary, arithmetic, bitwise and comparison operators, functions to sum, join and iterate arrays.

A wide range of smart components

You can use different components like Text, Table and Barcode and define formatting formats to number and date values. It is possible to group, filter and sort lists and tables without a need to modify the data set on your side.

Merge template and data via API

Powerful REST API to merge templates with data from your software. Just send the template identifier and JSON data to get the PDF.

I would recommend PDF Generator API to everyone that needs to print something into PDF. Think about it: if you are creating software that focuses on accounting then you want to focus on accounting. You shouldn't waste time with coding fancy forms that you can easily drag-drop using PDF Generator API.

PDF Generator API allows our customers to quickly design and print multiple template types for Invoices, Picking/Packing Slips, Drop Notes, Address labels and pretty much any other document. Building a similar functionality in-house would have cost a lot of money in terms of resource.
