pdfik 0.2.0

Official Python SDK for the PDFik PDF generation API

pdfik

Official Python SDK for PDFik — the premium, fast, and reliable PDF generation API.

Convert HTML markup or any public URL into pixel-perfect PDF documents in seconds, powered by scalable browser rendering.

Features

• Type Safety: Type hints for all options and response objects.
• Sync & Async: Exposes both PdfikClient and AsyncPdfikClient using the modern httpx engine.
• Auto Retry: Automatic exponential backoff for 5xx and 429 (Rate Limit) errors powered by tenacity.
• DX Affordances: Built-in polling logic (wait_for_job) and file download helpers.

Installation

pip install pdfik

Quick Start

Convert public URL to PDF (Sync)

from pdfik import PdfikClient, PdfOptions, MarginOptions

# Initialize the client
client = PdfikClient(api_key="sk_live_...")

# 1. Submit the URL to be rendered
job = client.url_to_pdf(
    "https://example.com",
    options=PdfOptions(
        format="A4",
        landscape=False,
        print_background=True,
        margin=MarginOptions(top="10mm", bottom="10mm")
    )
)

print(f"Job created: {job.job_id}. Waiting for rendering...")

# 2. Poll until the job completes
result = client.wait_for_job(job.job_id)
print(f"Job finished! Pages: {result.pages_count}")

# 3. Download the PDF bytes
pdf_bytes = client.download_pdf(job.job_id)

with open("output.pdf", "wb") as f:
    f.write(pdf_bytes)
print("PDF saved to output.pdf")

# Close connection pool
client.close()

Convert raw HTML to PDF (Async)

import asyncio
from pdfik import AsyncPdfikClient, PdfOptions

async def main():
    async with AsyncPdfikClient(api_key="sk_live_...") as client:
        job = await client.html_to_pdf(
            "<h1>Hello World</h1><p>Sent from PDFik Python SDK</p>",
            options=PdfOptions(format="Letter")
        )
        
        result = await client.wait_for_job(job.job_id)
        print(f"Job finished! Status: {result.status}")
        
        pdf_bytes = await client.download_pdf(job.job_id)

asyncio.run(main())

Get the direct download URL

Get the direct API download URL for the generated PDF (requires the "X-API-Key" header to download):

file_info = client.get_file_url(job.job_id)
print(f"Direct Download URL: {file_info.download_url}")

Handling Webhooks

If you specify webhook_url in the options of url_to_pdf or html_to_pdf, PDFik will send an HTTP POST request to your server when the rendering job is finished.

You should verify the authenticity of the webhook by validating the signature. We provide a static helper verify_webhook_signature in PdfikClient for this purpose.

Example (FastAPI):

from fastapi import FastAPI, Request, HTTPException
from pdfik import PdfikClient

app = FastAPI()

# Get your webhook secret from the PDFik Dashboard
WEBHOOK_SECRET = "whsec_..."

@app.post("/webhook")
async def handle_webhook(request: Request):
    # Retrieve headers
    headers = dict(request.headers)
    
    # Retrieve the raw payload bytes
    raw_body = await request.body()
    
    # Verify signature
    is_valid = PdfikClient.verify_webhook_signature(raw_body, headers, WEBHOOK_SECRET)
    
    if not is_valid:
        raise HTTPException(status_code=400, detail="Invalid signature")
        
    # Process event
    event = await request.json()
    print(f"Received webhook event: {event.get('event_type')} for job: {event.get('job_id')}")
    
    return {"received": True}
