​
Overview

n8n is a workflow automation tool to connect services and build automations without writing code. The official OpenRegister nodes for n8n let you search for companies, fetch company details, owners, holdings, financials, and documents directly inside your flows.

​
Prerequisites

  • An OpenRegister API key — get one in the OpenRegister Keys
  • n8n with Community Nodes enabled

​
Installation

  1. In n8n, go to Settings → Community Nodes → Install.
  2. Enter the package name: @oregister/n8n-nodes-openregister and confirm.
  3. Restart n8n if prompted.

​
Authentication

  1. In n8n, open Credentials → New → search for “OpenRegister”.
  2. Paste your API key into the API Key field.
  3. Save the credentials and select them in your OpenRegister nodes.

​
Available nodes

The package provides nodes that map to common OpenRegister API endpoints. Typical actions include:
  • Company search (simple)
  • Company information
  • Company owners
  • Company holdings
  • Company financials
Exact inputs and outputs are documented in each node within n8n and align with the API responses described in this documentation.

​
Example: Enrich companies with details and financials

This example shows a simple flow to search a company and fetch its details and financials.
  1. Add a Trigger (e.g., Manual Trigger).
  2. Add “OpenRegister: Search Companies” with a query (e.g., “Miles Mobility”).
  3. Add “OpenRegister: Get Company” and set Company ID to the first result from step 2.
  4. (Optional) Add “OpenRegister: Get Financials” using the Company ID from step 3.
  5. Continue your flow (e.g., store data, send notification, or enrich a CRM).
To try a ready‑made flow, import the example workflow from the repository’s examples folder linked above.

Troubleshooting

  • 401 Unauthorized: Check that your credentials are set and selected in the node.
  • 402 Payment Required: Your account lacks credits for this endpoint. Top up credits.
  • 429 Too Many Requests: You have hit a rate limit. Add a Wait node or lower concurrency.
  • 5xx Server Error: Retry with a Wait/Retry pattern. If persistent, contact support.
