Zindle API Documentation

Convert HTML into PDF documents with a single API call. This guide covers everything you need to integrate Zindle into your application.

Quickstart

Three steps to your first PDF.

1. Get an API key. Sign in at app.zindle.com.au, open API Keys, and create a key. Copy it immediately — the full key (znd_…) is shown only once.

2. Make a request. Send your HTML to the render endpoint:

curl -X POST https://api.zindle.com.au/v1/render \
  -H "Authorization: Bearer znd_your_key_here" \
  -H "Content-Type: application/json" \
  -d '{"html": "<h1>Hello, PDF</h1>"}' \
  --output hello.pdf

3. That's it. The response body is the raw PDF. The example above writes it to hello.pdf. The response is binary application/pdf — pipe it to a file or stream it, don't print it to a terminal.
