activepieces-polydoc

An Activepieces community piece for PolyDoc, a REST API that converts HTML or URLs to PDF, captures screenshots, and generates EU-compliant e-invoices (Factur-X / ZUGFeRD hybrid PDF/A-3).

One piece, three actions:

• Convert to PDF - layout, margins, page format, page ranges, bookmarks, accessible/tagged PDFs.
• Capture Screenshot - PNG / JPEG / WebP, full page, viewport and device-pixel-ratio control, file or base64 output.
• Generate E-Invoice - Factur-X or ZUGFeRD, profiles from minimum to extended.

Each action takes content from a URL, an inline HTML string, or a saved template (with Liquid templateData). The result is returned as a file by default, or uploaded to your cloud storage (presigned URL) or delivered to a webhook.

Installation

In Activepieces: Settings -> My Pieces -> Install Piece, then enter the npm package name activepieces-polydoc.

For a self-hosted instance you can also upload a built tarball via Platform Admin -> Setup -> Pieces.

Connection

Create a PolyDoc connection with an API key from dashboard.polydoc.tech (API Keys). The key is sent as Authorization: Bearer <key>. Toggle Sandbox to test against sandbox quota (output is watermarked). The connection test runs a tiny forced-sandbox screenshot, so it never touches production quota.

Anything not in the UI?

Every action has an Advanced (JSON) field that is deep-merged into the request body, so any API capability not surfaced as a control (e.g. pdf.watermark, pdf.pdfa, pdf.encryption, render.*, request.*) is still reachable. See the full request schema at docs.polydoc.tech.

Example flows

Importable flow templates live in examples/, one per use case. Import them via Flows -> Import Flow:

• pdf-from-template-webhook.json - invoice PDF from a saved template, triggered by a webhook.
• url-screenshot-scheduled.json - scheduled full-page screenshot of a URL.
• einvoice-webhook-to-pdf.json - ZUGFeRD / EN 16931 e-invoice from a webhook payload.

Development

npm install
npm run build       # tsc -> dist/
npm run lint        # eslint
npm test            # unit tests (request body builder)
npm run scrub:check # fail on em-dashes in UI/customer text

Live smoke test against the real API (uses sandbox quota, needs network access to api.polydoc.tech):
