How do I generate PDFs from HTML or URLs using an API?

Two endpoints, one API key — pick your input:

POST /api/v1/convert-html HTML → PDF

Send raw HTML markup, get a rendered PDF back.

POST /api/v1/convert URL → PDF

Send a live page URL — JavaScript rendering included.

Then, for either endpoint:

1 Poll GET /api/v1/status/{job_id} until ready
→
2 Download GET /api/v1/download/{job_id}
Example A — HTML to PDF with curl
# 1) Submit raw HTML
curl -X POST https://docuqueue.com/api/v1/convert-html \
  -H "api-key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"html": "<html><body><h1>Hello PDF</h1></body></html>"}'

# → {"job_id": "abc123", "status": "queued"}

# 2) Poll until ready, then download
curl https://docuqueue.com/api/v1/status/abc123 \
  -H "api-key: YOUR_API_KEY"
curl -o result.pdf https://docuqueue.com/api/v1/download/abc123 \
  -H "api-key: YOUR_API_KEY"

# URL instead of HTML? POST /api/v1/convert with {"urls": ["https://example.com"]}
Example B — HTML to PDF with Python
import requests

resp = requests.post(
    "https://docuqueue.com/api/v1/convert-html",
    headers={"api-key": "YOUR_API_KEY"},
    json={"html": "<html><body><h1>Hello PDF</h1></body></html>"},
)
job_id = resp.json()["job_id"]

# Poll status, then download the finished PDF
pdf = requests.get(
    f"https://docuqueue.com/api/v1/download/{job_id}",
    headers={"api-key": "YOUR_API_KEY"},
)
open("result.pdf", "wb").write(pdf.content)

Batch or JavaScript-heavy pages? See the web page to PDF endpoint for URL options like wait-for-element and custom headers. Full request and response schemas live in the API reference.
