curl -X POST \
  "https://rest.apitemplate.io/v2/create-pdf?template_id=6b277b234d395eca" \
  --header "Content-Type: application/json" \
  --header "X-API-KEY: YOUR_API_KEY" \
  --data '{"invoice_no": "INV38379", "total_amount": 82542.56}'

# {"status": "success", "download_url": "https://pdf.apitemplate.io/..."}

const url =
  "https://rest.apitemplate.io/v2/create-pdf?template_id=6b277b234d395eca";

const res = await fetch(url, {
  method: "POST",
  headers: {
    "Content-Type": "application/json",
    "X-API-KEY": "YOUR_API_KEY",
  },
  body: JSON.stringify({ invoice_no: "INV38379", total_amount: 82542.56 }),
});

const { download_url } = await res.json();

import requests

res = requests.post(
    "https://rest.apitemplate.io/v2/create-pdf",
    params={"template_id": "6b277b234d395eca"},
    headers={"X-API-KEY": "YOUR_API_KEY"},

download_url = res.json()["download_url"]

var url = "https://rest.apitemplate.io/v2/create-pdf"
        + "?template_id=6b277b234d395eca";
var json = "{\"invoice_no\": \"INV38379\", \"total_amount\": 82542.56}";

var request = HttpRequest.newBuilder().uri(URI.create(url))
    .header("Content-Type", "application/json")
    .header("X-API-KEY", "YOUR_API_KEY")
    .POST(HttpRequest.BodyPublishers.ofString(json))
    .build();

var res = HttpClient.newHttpClient()
    .send(request, HttpResponse.BodyHandlers.ofString());

Automate PDF and image generation with no-code platforms or the REST API

One reusable template, one JSON payload. Send data from a Zapier zap, a Make.com scenario, an n8n workflow or your own backend — every integration calls the same endpoint and returns a ready-to-share file URL.

Generate synchronously for on-screen downloads or asynchronously with webhooks for batches, and keep processing and storage in your chosen region: US, EU, Singapore or Australia.

Native integrations for the tools your team already runs, plus a REST API for everything else.

APITemplate.io is such an easy application to use. Simple, intuititive, and code free. At simplehuman, we render all our commercial invoices, dispatch notes, and multiple other templates. The ability to create multiple layouts, and group them into a logical container - makes our lives much simpler. This is a great tool to use, both affordable, and the support service turnaround time is second to none! Defintely worth the subscription!
Ron P.Product Manager
Elation Factory
Had an issue with template implementation via Make and reached out for support. Within minutes, I got a response and was soon on a Zoom call resolving it. Despite the issue not being directly related to APITemplate.io, their team efficiently guided me to the right formatting. Many thanks!

Factored Quality
We use APITemplate to generate key documentation we need to work with our industry partners. We are building a digital solution in an antiquated industry, which means we need to communicate data to our partners in the format that they are accustomed to (pdf forms). APITempate makes it easy for us to do this!
Jean-Paul HornPublisher
iCulture.nl
We love APITemplate.io for its simplicity and ease of use. Just setup once and "forget" about it due to its fabulous 3rd party integration. New features are regularly added, and reasonable custom requests are honoured within days.

@kwfricke
APITemplate.io is one of the best services I have worked with in a very, very long time. They are super responsive and a joy to work with. If you are struggling with PDF's, like I was, check 'em out!
Jacob MonashAutomation Specialist
ai4.co
We run conferences with a number of speakers, each requiring an individual speaker profile. We used to create all of these profiles manually, but by incorporating APItemplate into our Zapier workflow, our team can generate a complete image with all of the speakers information in one click. Using the template editor is a bit of a learning curve, but the support team is very responsive and helpful.
George Cooper
APITemplate.io is great. I love being able to quickly use HTML and CSS templates with dynamic variables to create documents. Support is also fast and responsive. Great vendor!
