PlentyONE n8n Community Node

Interact with the PlentyONE (formerly plentymarkets) REST API directly from your n8n workflows. This community node focuses on dynamic request handling so you can cover both well-known endpoints and ad-hoc API calls without waiting for custom code changes.

Highlights

• ✅ Automatic session handling via n8n preAuthentication – the access token is cached and refreshed only when needed.

• ✅ Classic Custom Request operation with support for sending payloads even on GET/HEAD calls (body → query parameters).

• ✅ New Request via JSON Definition operation to paste or inject complete request descriptions, e.g.:

• ✅ Optional Fetch All Pages toggle that follows PlentyONE pagination automatically and outputs the collected entries.

  {
    "method": "GET",
    "endpoint": "/rest/v2/properties/relations",
    "body": {
      "with": "values",
      "groupId": 44,
      "propertyId": 394,
      "type": "item",
      "targetId": 99211
    }
  }

  Arrays are supported as well – just provide a JSON array of request objects to execute them sequentially in one run.

• ✅ Local PlentyONE icon bundled with the node for easier identification inside n8n.

Installation

Install the package inside your n8n instance (desktop, self-hosted or cloud with custom packages enabled):

npm install n8n-nodes-plentyone

Restart n8n afterwards so the node metadata is reloaded.

Compatibility: The internal node type stays n8n-nodes-plentymarkets.Plentymarkets so existing workflows continue to work after upgrading from older releases.

Credentials

Create a new credential record of type PlentyONE API and fill in:

| Field | Description | |--------------|-----------------------------------------------------------------------------| | Base URL | Base URL of your PlentyONE environment (e.g. https://example.plentyone.de) | | Username | PlentyONE username used for API login | | Password | Corresponding password |

The node stores the access token invisibly and refreshes it automatically before expiry.
No external Redis/filesystem cache is required, so the credential works in hosted/cloud setups too.

Operations

Custom Request

Configure the HTTP method and endpoint in the node UI. The “Payload / Query (JSON)” parameter accepts a JSON object:

• For GET/HEAD requests the object is sent as query parameters.
• For all other methods the object is sent as JSON body.

Enable Fetch All Pages when the API response uses the PlentyONE pagination format (page, isLastPage, entries, …). The node will loop through pages (ignoring any provided page value) until isLastPage === true, returning each entry as a separate item. See the PlentyONE REST documentation for details on paginated endpoints.

Request via JSON Definition

Provide a JSON object (or array of objects) with the following optional fields:

| Field | Type | Notes | |----------|-----------------|-----------------------------------------------------------------------| | method | string | Defaults to GET. | | endpoint | string | Required. | | body | object | Used as JSON body (or merged into query for GET/HEAD). | | query | object | Explicit query string parameters. | | headers | object | Custom headers added to the request. |

Example payload for a PUT request:

{
  "method": "PUT",
  "endpoint": "/rest/listings/markets/histories/update/",
  "body": {
    "id": [959893, 919078],
    "options": ["quantityAndPrice"]
  }
}

When Fetch All Pages is enabled for this operation, every GET request definition in the JSON will be paginated automatically, following the same logic as the Custom Request.

Development

npm install
npm run build

npm run build compiles TypeScript and copies the PlentyONE icon plus operation schema into dist/.
