Is there a Verteco module for n8n?

No connector is needed: SAPI-SK is an ordinary REST interface with an OpenAPI specification and our webhooks are signed HTTP requests; the HTTP step of your tool handles both.

What do I have to build in n8n?

The HTTP Request node calls SAPI-SK directly (token, sending, status), the Webhook node receives our signed webhooks about received and delivered invoices. You build the UBL XML (Peppol BIS 3.0) in a template following our samples on /vzory and check it in the validator; the API accepts ready UBL.

How much does a managed custom connection cost?

A one-off fee, priced by scope (formats, number of companies, way of connecting). Write to peppol@verteco.digital or call +421 944 488 269 (Mgr. Miriama Mrkávková) and we will propose the exact procedure and price.

How much does it cost?

The service costs from €2/month excl. VAT per company ID (IČO) that sends or has the Data archive switched on (the default for new companies): receiving, sending and the archive of originals in the EU. A company with the archive off that only receives pays nothing (up to 1,000 invoices a month). During the voluntary period before the mandate of 1 January 2027 everything is free of charge.

Integrations / Automation and no-code / n8n

E-invoices via n8n

Via HTTP and webhooks

n8n is an automation platform with open source code (Sustainable Use licence) that you host yourself or use in the cloud. The HTTP Request node calls SAPI-SK directly (token, sending, status), the Webhook node receives our signed webhooks about received and delivered invoices. A workflow in n8n: a trigger (a new invoice in your system), building the UBL XML following our samples, an HTTP Request node for POST /sapi/document/send and storing the status. For receiving use the Webhook node with our invoice.received event. No ready-made connector is needed: an HTTP step and a webhook are enough.

The honest current state

•No ready-made connector is needed, an HTTP step and a webhook are enough.
•The connection through the SAPI-SK REST interface (OpenAPI, public sandbox) works today.
•Sending from the portal (form, file, bulk) works independently of the automation.
