Resolve and create KlickTipp tags from names with optional prefixes

Community Node Disclaimer This workflow uses KlickTipp community nodes, available for self-hosted n8n instances only.

Introduction

This workflow receives an array of tag names, optionally applies a prefix to all tags, checks which tags already exist in KlickTipp, creates the missing ones, and returns a unified array of resolved tag names. This allows you to reuse the same get or create tags logic across multiple automations without duplicating tag-handling logic.

It’s especially useful when tags are namespaced by a tool or source (for example, Zoho | Webinar) and you want to enforce consistent tagging conventions across different workflows.

How it works

Accepts input: tagNames[] — array of base tag names prefix — optional string applied to all tag names Splits tagNames[] into individual items and builds the final tag name: If prefix is provided → prefix tagName (e.g. Zoho | Webinar) If prefix is empty → tagName (e.g. Webinar) Loads the existing KlickTipp tags and matches them by name. Creates tags that do not yet exist. Combines existing and newly created tags. Returns a single aggregated array of resolved tag names, without duplicates.

Setup Instructions

1. Credentials Configure your KlickTipp credentials in the KlickTipp nodes.

2. How to call this sub-workflow

From a parent workflow, use an Execute Sub-workflow node and pass:

Without prefix
{
"tagNames": ["Webinar", "Newsletter]
}

With prefix {
"prefix": "Zoho | ",
"tagNames": ["Webinar", "Newsletter"]
}

Resulting tag names resolved or created in KlickTipp: Zoho | Webinar Zoho | Newsletter

Output

Returns a unified array of tag names:

{
"tags": ["Zoho | Webinar", "Zoho | Newsletter"]
} Testing

Test with a mix of existing and new tag names. Confirm new tags appear in KlickTipp when missing. Verify that the output contains all expected tag names, without duplicates. If a prefix is used, ensure tags are resolved or created under the correct namespace (for example, Zoho | …). Reuse the returned tags[] in downstream workflows (for example, for filtering, comparison, or further tagging logic).
