Getting Started
Sign in, mint an API key, design a template, then POST a template ID and JSON.
Introduction
Shablonix generates PDFs from visual templates, and compiles email letters to inbox HTML. The public API is REST with API-key auth.
PDF generate
POST /v1/generatewith a template ID and JSON. Stream the file or take a job to poll.Visual templates
Design in the editor with Atoms, Format, and Inspect. Preview against sample JSON before anything ships.
HTTP first
JSON in, PDF or HTML out. A TypeScript client lives in
packages/sdk(examples/sdk-demo). You do not need an SDK.Email plugin
Mint an embed session from your backend. Compile with
POST /v1/emails/compile. A React host example lives inexamples/react-embed-demo. Compiled mail is not stored.
Quick Start
Get up and running with Shablonix API in just a few steps:
- 1
Create an account
Sign up at shablonix.online/sign-up to get your API credentials.
- 2
Generate an API key
Navigate to Settings → API Keys and create a new key.
- 3
Make your first API call
Use the code examples below to generate your first document.
Installation
Install our official SDK for your preferred language:
npm install @shablonix/sdk No SDK Required
First API Call
Generate a PDF from a template ID and JSON. Use a real template ID from your dashboard.
If account webhooks are configured, document.completed is still delivered when the file is ready.
import { Shablonix } from '@shablonix/sdk';
const client = new Shablonix(process.env.SHABLONIX_API_KEY!);
const pdf = await client.generatePdf({
templateId: 'meridian-invoice',
data: { invoice: { number: 'INV-2026-001' } },
});
const bytes = await client.downloadGenerationBytes(pdf); Compile an email letter the same way. The response is HTML and text; compiled mail is not stored.
const letter = await client.compileEmail({
templateId: 'cmEmailTemplateId',
data: {
customer: { name: 'Ada Lovelace' },
invoice: { number: 'INV-2048', total: '€149.00' },
},
});
await resend.emails.send({
from: 'billing@your-app.example',
to: 'ada@example.com',
...letter.providers.resend,
}); Next Steps
