API Overview — API Reference | Document Stack Docs

Introduction

The Document Stack API is a RESTful API that lets you generate, manage, and retrieve PDF documents programmatically. Every feature available in the dashboard can be accessed through the API.

Base URL

text

https://api.documentstack.dev/api/v1

Authentication

All API requests require authentication via an API key passed as a Bearer token in the Authorization header:

cURL Example

curl -X POST https://api.documentstack.dev/api/v1/generate \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"templateId": "tmpl_abc123", "data": {"name": "Alice"}}'

Keep Keys Secret

Never expose your API key in client-side code. Always make API calls from your server or trusted backend.
