apilayer pdflayer SDKs & Libraries: Integration Guide (2026)

SDKs overview

apilayer pdflayer provides a REST API for converting web content, specifically HTML and URLs, into PDF documents. While the service primarily operates via direct HTTP GET requests, it offers official and community-contributed libraries and code examples to simplify integration across various programming languages. These SDKs and libraries abstract the underlying HTTP communication, handling URL construction, parameter encoding, and response parsing, which can accelerate development and reduce potential errors during API interaction. The core functionality revolves around specifying a URL or raw HTML content, along with conversion parameters such as page format, margins, and custom CSS, to generate the desired PDF output.

The API's design emphasizes simplicity, allowing developers to integrate PDF generation capabilities with minimal setup. The primary method of interaction involves constructing a GET request to the pdflayer API endpoint, including an API key for authentication and various optional parameters to customize the PDF output. For instance, developers can specify whether to include headers and footers, set custom delays before rendering, or define specific viewport sizes for responsive web content. The generated PDF is then returned as a binary stream or can be stored in a specified location. The availability of examples in common languages like PHP, Python, and Ruby helps developers quickly adapt the API to their existing projects. For more in-depth configuration options and API endpoints, refer to the pdflayer official documentation.

Official SDKs by language

apilayer pdflayer provides official code examples and integration guides for several programming languages, which serve as de facto SDKs by illustrating direct API interaction patterns. These are designed to help developers quickly implement the API's core functionalities without needing to build client-side HTTP request logic from scratch. The primary method for interaction is through HTTP GET requests, which these examples abstract into language-specific functions or classes.

The following table outlines the key languages for which official support and examples are provided, along with common installation approaches. While not always distributed as traditional package manager installations, the provided code snippets and libraries are functionally equivalent to SDKs, offering ready-to-use client logic.

Each of these approaches focuses on constructing the API request URL with the necessary parameters, including the API key and the target URL or HTML content to be converted. For example, the Python requests library simplifies making web requests significantly, allowing developers to pass parameters as a dictionary, which the library then encodes into the URL query string. Similarly, PHP's cURL extension provides extensive control over HTTP requests, enabling precise configuration for various API interactions.

Installation

While pdflayer does not distribute conventional SDK packages through language-specific repositories (like npm for Node.js or Maven for Java), integrating with the API primarily involves using standard HTTP client libraries available in most programming languages. The installation process, therefore, focuses on setting up these HTTP clients and then implementing the logic to construct and send requests to the pdflayer API.

Python

For Python, the requests library is a widely used HTTP client. To install it, use pip:

pip install requests

After installation, you can import it into your Python script and use it to make GET requests to the pdflayer API endpoint. This library handles URL encoding and response parsing, simplifying the API interaction process. More details on the requests library can be found in its official Python Requests documentation.

PHP

In PHP, you can use the built-in cURL extension, which is often enabled by default. If not, you might need to enable it in your php.ini configuration. For a more object-oriented approach, the Guzzle HTTP client is a popular choice:

composer require guzzlehttp/guzzle

Guzzle simplifies making HTTP requests and handling responses, providing a more robust solution for complex API integrations compared to raw cURL functions. The Guzzle PHP documentation provides comprehensive usage examples.

Ruby

For Ruby, the httparty gem is a common choice for making HTTP requests:

gem install httparty

Alternatively, Ruby's standard library includes Net::HTTP, which can be used without additional installations, though httparty offers a more concise syntax. Review the HTTParty Ruby documentation for quickstart instructions.

Go

Go applications typically use the standard library's net/http package, which requires no external installation for making HTTP requests. You simply import the package and use its functions to construct and send requests.

jQuery (Client-Side JavaScript)

For client-side web applications, jQuery's AJAX methods ($.ajax() or $.get()) can be used. jQuery itself needs to be included in your project, typically via a CDN or local file:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.6.0/jquery.min.js"></script>

Note that direct client-side API calls to pdflayer might expose your API key, which is generally not recommended for security reasons. Server-side proxies are often preferred for such operations.

Quickstart example

This quickstart example demonstrates how to convert a URL to a PDF using the pdflayer API with Python and the requests library. Replace YOUR_API_ACCESS_KEY with your actual pdflayer API key and https://example.com with the URL you wish to convert.

Python Quickstart

First, ensure you have the requests library installed (pip install requests).

import requests

# Your pdflayer API access key
ACCESS_KEY = 'YOUR_API_ACCESS_KEY'

# The URL you want to convert to PDF
TARGET_URL = 'https://www.apispine.com/documentation'

# Construct the API request URL
api_url = f'https://api.pdflayer.com/api/convert?access_key={ACCESS_KEY}&url={TARGET_URL}'

# Optional parameters (example: set page format to A4 and landscape orientation)
params = {
    'page_format': 'A4',
    'page_orientation': 'landscape'
}

try:
    # Make the GET request to the pdflayer API
    response = requests.get(api_url, params=params, stream=True)
    response.raise_for_status() # Raise an HTTPError for bad responses (4xx or 5xx)

    # Check if the response content-type is PDF
    if 'application/pdf' in response.headers.get('Content-Type', ''):
        # Define the output file name
        output_filename = 'output.pdf'
        
        # Save the PDF content to a file
        with open(output_filename, 'wb') as pdf_file:
            for chunk in response.iter_content(chunk_size=8192):
                pdf_file.write(chunk)
        
        print(f'PDF successfully generated and saved as {output_filename}')
    else:
        print(f'API Error: Unexpected content type. Response: {response.text}')

except requests.exceptions.RequestException as e:
    print(f'An error occurred during the API request: {e}')
except IOError as e:
    print(f'An error occurred while writing the file: {e}')

This script constructs the API endpoint URL, adds an API key and the target URL, and includes optional parameters for page formatting. It then sends a GET request to the pdflayer API. If successful, the API returns the PDF content as a binary stream, which is then saved to a local file named output.pdf. Error handling is included to catch network issues or API-specific errors. For additional parameters and advanced customization options, refer to the pdflayer API documentation.

Community libraries

While apilayer pdflayer provides official code examples that function as integration guides, the open-source community may develop additional libraries or wrappers to further streamline interactions with the API. These community-contributed tools can offer features like improved object-oriented interfaces, advanced error handling, or integration with specific frameworks beyond what the official examples cover. However, the availability and maintenance of such libraries can vary.

Due to the API's straightforward HTTP GET request model, many developers find that directly using standard HTTP client libraries (like Python's requests or PHP's Guzzle) is sufficient for integration, negating the immediate need for complex community SDKs. When considering a community library, it is advisable to check its active maintenance, documentation, and compatibility with the latest API version. Resources like GitHub or language-specific package repositories (e.g., PyPI for Python, Packagist for PHP) are the primary places to search for such contributions. Always verify the source and security of any third-party library before incorporating it into a production environment. For general best practices in API client development, the Mozilla Developer Network's Fetch API guide offers insights into robust HTTP request handling, which can be applied to custom client implementations.
