Latenode

Prerequisites​

  • A PolyDoc account and API key — sign up for free, no credit card required. The free plan includes 150 PDF conversions per month.
  • A Latenode account — sign up for free, no credit card required.

Use Case 1: Generate PDFs from Database Events​

Generate PDFs from database, schedule, or app events using Latenode's visual scenario builder.
Database trigger node → HTTP Request node (PolyDoc API) → Email node

Create a new scenario​

Open Latenode and click New Scenario. Give it a name (e.g. "Database to PDF").

Add a trigger node​

Add a trigger node — choose a database trigger, a schedule (cron), or an app event depending on your data source. Configure the connection credentials and the event to watch.

Add an HTTP Request node for PolyDoc​

Add an HTTP Request node and configure:

  • URL: https://api.polydoc.tech/pdf/convert
  • Method: POST
  • Headers: Authorization: Bearer YOUR_API_KEY and X-Sandbox: true (get your API key from the Dashboard)
  • Content-Type: application/json
  • Body: JSON mapping trigger data to your PolyDoc template fields.

Add an output node​

Add an email node or storage node to deliver the PDF. Map the recipient, subject, and attach the binary PDF from the HTTP response.

Test and deploy​

Click Test to run the scenario with sample data. Verify the PDF output, then click Deploy to activate the scenario in production.

Use Case 2: Webhook to PDF​

Accept webhook data, optionally transform it with JavaScript, and generate a PDF.
Webhook node → JavaScript node (prepare data) → HTTP Request node (PolyDoc) → Send email

Add a Webhook trigger node​

Create a new scenario and add a Webhook trigger node. Latenode generates a unique URL — copy it and configure your external service to POST data to it.

Add a JavaScript node to transform data​

Optionally add a JavaScript node to transform the incoming webhook data. Use it to rename fields, calculate totals, or format dates before passing data to PolyDoc.

Add HTTP Request node for PolyDoc​

Add an HTTP Request node configured for the PolyDoc API. Set the URL, method, headers (Authorization, X-Sandbox, Content-Type), and map the transformed data to the JSON body.

Deliver the PDF​

Add a delivery node (email, cloud storage, or another app) to send the generated PDF. Test the scenario end-to-end, then deploy it.
