Convertica API

Why Convertica API

Quick start

1. Issue a key in your dashboard

Go to your API Keys dashboard and create a named key. The full key is shown once — copy it immediately.

2. Make a request

curl example — convert a PDF to Word:

curl -X POST https://convertica.net/api/v1/pdf-to-word/ \
  -H "Authorization: Bearer cvk_live_xxxxxxxxxxxxxxxx" \
  -F "[email protected]" \
  -o output.docx

Python example

import requests
r = requests.post(
    "https://convertica.net/api/v1/pdf-to-word/",
    headers={"Authorization": "Bearer cvk_live_xxxxxxxxxxxxxxxx"},
    files={"pdf_file": open("input.pdf", "rb")},
)
with open("output.docx", "wb") as f:
    f.write(r.content)

Node.js example

import fs from "node:fs";
import { request } from "undici";
const form = new FormData();
form.set("pdf_file", new Blob([fs.readFileSync("input.pdf")]), "input.pdf");
const r = await request("https://convertica.net/api/v1/pdf-to-word/", {
  method: "POST",
  headers: { Authorization: "Bearer cvk_live_xxxxxxxxxxxxxxxx" },
  body: form,
});
fs.writeFileSync("output.docx", Buffer.from(await r.body.arrayBuffer()));

Authentication

Send your API key as a Bearer token in the Authorization header. Keys are tied to your subscription — revoke and rotate any time from the dashboard.

• Up to 10 active keys per account, with optional named scope
• Prefix shown in dashboard for easy identification (full key shown only at creation)
• Per-key monthly quota tied to the subscription tier — counter resets on the 1st
• Hashed at rest; if a key leaks, revoke it and issue a new one in seconds

Async webhooks

Large jobs return a task ID and run in background. Either poll the task endpoint, or set a callback URL and let Convertica push the result.

curl -X POST https://convertica.net/api/v1/pdf-to-word/ \
  -H "Authorization: Bearer cvk_live_xxxxxxxxxxxxxxxx" \
  -F "[email protected]" \
  -F "callback_url=https://yourapp.example/convertica-hook"

Webhook payloads are signed with HMAC-SHA256 using the secret shown in your dashboard. Verify the X-Convertica-Signature header before trusting the body.
