Documents from a single API call

Real documents teams are generating today

Design a template once, then generate professional PDF and Excel documents from your data — no Puppeteer, no ExcelJS, no headless browsers.

Design a template

Build your document in the visual designer, or define it as JSON — 28 components, charts, barcodes, and form fields.

Send your data

POST a template ID and your JSON data to one endpoint — from any language, SDK, or no-code platform.

Get PDF or Excel

The native engine renders your document in under a second and returns a download URL. Same template, either format.

Where teams put Rynko to work

Not demos. Actual document workflows running in production today.

Most Common
Invoices & Receipts
Branded invoices and receipts, generated on demand
Your billing system needs to produce clean, on-brand invoices for every order — with line items, taxes, totals, and payment terms rendered exactly the same way every time.

How Rynko does it

Design an invoice template once in the visual designer, then post your order data to a single API call. Rynko returns a pixel-perfect PDF in under a second — no headless browser, no HTML-to-PDF glue code.

What you get

Line item tables
Auto-calculated totals
PDF or Excel output
Business Reports & Analytics
Turn raw data into polished, chart-rich reports
Every week your team needs sales, operations, or performance reports built from database rows — with charts, summary tables, and consistent formatting your stakeholders can trust.

How Rynko does it

Map your data to a report template with native charts and tables. Generate the same report as a PDF for distribution or an Excel workbook with live formulas — from one template.

What you get

8 chart types
Summary tables
Multi-page layouts
Certificates & Credentials
Issue certificates and credentials at scale
You need to issue completion certificates, awards, or credentials — one per recipient — with names, dates, and reference numbers dropped into a precise design.

How Rynko does it

Batch-generate hundreds of certificates from a single template and a list of recipients. Rich text, custom fonts, and precise positioning keep every certificate on-brand.

What you get

Batch generation
Custom fonts
Rich text (TextRuns)
Financial Statements
Audit-ready statements with formulas intact
Finance needs balance sheets, P&L statements, and reconciliations that reconcile to the cent — delivered as spreadsheets accountants can open and extend.

How Rynko does it

Generate Excel workbooks with real formulas, named ranges, and cell formatting, or the same statement as a PDF for sign-off. One template drives both formats.

What you get

Native Excel formulas
Cell formatting
PDF + Excel from one template
Contracts & Agreements
Ready-to-sign contracts with fillable fields
Sales and legal need contracts generated from deal data with correct clauses, formatting, and signature blocks — ready to send to the counterparty.

How Rynko does it

Merge deal data into a contract template and render a print-ready PDF with fillable form fields and signature placeholders. No manual copy-paste, no formatting drift.

What you get

9 PDF form field types
Signature placeholders
Conditional sections
Shipping & Logistics Docs
Labels, manifests, and delivery paperwork
Every shipment needs labels, packing lists, and delivery notes with scannable barcodes — generated automatically as orders move through fulfillment.

How Rynko does it

Render shipping labels and manifests with built-in barcode and QR support. Trigger generation straight from your warehouse or order system via API or webhook.

What you get

10 barcode formats
QR codes
Trigger via webhook
One template, every format

Design once. Generate PDF and Excel.

A native rendering engine — built on Yoga layout, not a headless browser — produces both PDF and Excel from the same template definition. Sub-second, deterministic, and precise.

28

Components

Text, headings, tables, images, columns, loops, and conditionals — plus rich text with TextRuns for fine-grained inline styling.

8 + 10

Charts & barcodes

Eight chart types and ten barcode formats render natively — no external services, no screenshotting a web page.

9

PDF form fields

Fillable text inputs, checkboxes, radios, dropdowns, dates, and signature placeholders for ready-to-sign documents.

<1s

Native engine renders most documents in under a second

JS + Excel

JavaScript expressions and native Excel formulas both supported

0

Headless browsers to install, patch, or scale

Scheduled Reporting

Generate reports straight from your database, on a schedule.

Run an on-premise agent inside your network to produce scheduled, data-driven PDF and Excel reports — a modern replacement for legacy tools like Cognos. Your data never leaves your environment: the agent works zero-knowledge, so Rynko never sees your database.

Built for e-commerce operations

Generate the paperwork every order needs — automatically, the moment it's placed.

Order Confirmations

Branded order confirmation PDFs generated the moment checkout completes.

Packing Slips

Warehouse-ready packing slips with itemized contents and order details.

Shipping Labels

Scannable shipping labels with barcodes, generated per shipment via API.

Return Labels & Receipts

Returns paperwork and receipts produced on demand from order data.

One call. Any document.

Post your template ID and data. Get back a PDF or Excel file. That's the whole API.

Generate a PDF
POST /api/v1/documents/generate
{
  "templateId": "invoice",
  "format": "pdf",
  "data": {
    "customer": "ACME Corp",
    "amount": 8500,
    "currency": "USD"
  }
}

// Returns: { "url": "https://..." }
Same template, as Excel
POST /api/v1/documents/generate
{
  "templateId": "invoice",
  "format": "xlsx",
  "data": {
    "customer": "ACME Corp",
    "amount": 8500,
    "currency": "USD"
  }
}

// Returns: { "url": "https://..." }

Why not just use Puppeteer or wkhtmltopdf?

Headless browsers are fragile

Puppeteer and wkhtmltopdf need constant patching, break on upgrades, and are painful to scale under load.

No Excel from the same source

HTML-to-PDF tools can't produce a real Excel workbook — you end up maintaining a second, separate pipeline.

One native engine

Rynko renders PDF and Excel from the same template with a native engine — sub-second, deterministic, nothing to host.

Design without code

Non-developers update documents in the visual designer. Your team ships template changes without a deploy.
