Documents, crafted.
Rendered in milliseconds.
Build a template once with the variables of your choice. Craftkit auto-generates a typed REST API and a unique webhook URL. Send the data, get a PDF. No infra. No glue code.
Visual template builder
Rich text, tables, images, conditional blocks, and loops. Type / to insert a variable.
You define the variables
No catalog of pre-baked fields. Name them anything. Craftkit derives the API contract automatically.
Versioned by default
Every publish creates an immutable version. Old API calls keep working forever.
API & inbound webhooks
Each template ships with a REST endpoint and a unique signed webhook URL. Wire Stripe, Zapier, or anything.

Built for engineers
TypeScript SDK, JSON Schema, OpenAPI snippets, HMAC-signed webhooks, retries with backoff.
How it works
From blank page to production document in four steps.
- STEP 1
Design the template
Lay out your document visually. Drop in variables and loops wherever you need merge data.
- STEP 2
Publish a version
Craftkit derives the variable manifest, generates a typed schema, and provisions an API endpoint + webhook URL.
- STEP 3
Send the data
POST /v1/templates/:slug/render from your backend, or have any external system POST the inbound webhook URL.
- STEP 4
Get the PDF
A signed asset URL is returned, plus an outgoing webhook to your system on completion.
A typed API per template, automatically
When you create a template called invoice with variables customer.name, invoiceNumber, and a loop items — this endpoint exists. Validated server-side. No extra config.
curl -X POST https://api.craftkit.dev/v1/templates/invoice/render \
-H "Authorization: Bearer ck_live_xxxxxxxx" \
-H "Content-Type: application/json" \
-d '{
"data": {
"customer": { "name": "Acme Corp", "email": "ap@acme.com" },
"invoiceNumber": "INV-0421",
"items": [
{ "name": "Widget", "qty": 5, "price": 9.99 }
],
"total": 49.95
}
}'Build your first template in five minutes.
