PDFGeneratorAPI

Introduction

PDF Generator API allows you easily generate transactional PDF documents and reduce the development and support costs by enabling your users to create and manage their document templates using a browser-based drag-and-drop document editor.

The PDF Generator API features a web API architecture, allowing you to code in the language of your choice. This API supports the JSON media type, and uses UTF-8 character encoding.

Base URL

The base URL for all the API endpoints is https://us1.pdfgeneratorapi.com/api/v4

For example

• https://us1.pdfgeneratorapi.com/api/v4/templates
• https://us1.pdfgeneratorapi.com/api/v4/workspaces
• https://us1.pdfgeneratorapi.com/api/v4/templates/123123

Editor

PDF Generator API comes with a powerful drag & drop editor that allows to create any kind of document templates, from barcode labels to invoices, quotes and reports. You can find tutorials and videos from our Support Portal.

Definitions

Organization

Organization is a group of workspaces owned by your account.

Workspace

Workspace contains templates. Each workspace has access to their own templates and organization default templates.

Master Workspace

Master Workspace is the main/default workspace of your Organization. The Master Workspace identifier is the email you signed up with.

Default Template

Default template is a template that is available for all workspaces by default. You can set the template access type under Page Setup. If template has "Organization" access then your users can use them from the "New" menu in the Editor.

Data Field

Data Field is a placeholder for the specific data in your JSON data set. In this example JSON you can access the buyer name using Data Field {paymentDetails::buyerName}. The separator between depth levels is :: (two colons). When designing the template you don’t have to know every Data Field, our editor automatically extracts all the available fields from your data set and provides an easy way to insert them into the template.

{
    "documentNumber": 1,
    "paymentDetails": {
        "method": "Credit Card",
        "buyerName": "John Smith"
    },
    "items": [
        {
            "id": 1,
            "name": "Item one"
        }
    ]
}

Rate limiting

Our API endpoints use IP-based rate limiting and allow you to make up to 2 requests per second and 60 requests per minute. If you make more requests, you will receive a response with HTTP code 429.

Response headers contain additional values:

Libraries and SDKs

Postman Collection

We have created a Postman Collection so you can easily test all the API endpoints without developing and code.

Client Libraries

All our Client Libraries are auto-generated using OpenAPI Generator which uses the OpenAPI v3 specification to automatically generate a client library in specific programming language.

• PHP Client
• Java Client
• Ruby Client
• Python Client
• Javascript Client

We have validated the generated libraries, but let us know if you find any anomalies in the client code.

Model Context Protocol (MCP) Server

Integrate document generation directly into your AI agents and LLM applications using our official Model Context Protocol (MCP) Server.

The MCP server provides a standardized interface that allows AI assistants (like Claude Desktop and other MCP-compatible clients) to securely interact with the PDF Generator API. With it, your AI applications can automatically fetch workspaces, retrieve templates, merge data, and generate PDF documents on the fly.

Authentication

The PDF Generator API uses JSON Web Tokens (JWT) to authenticate all API requests. These tokens offer a method to establish secure server-to-server authentication by transferring a compact JSON object with a signed payload of your account’s API Key and Secret. When authenticating to the PDF Generator API, a JWT should be generated uniquely by a server-side application and included as a Bearer Token in the header of each request.
