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).
