KlickTipp Tag Manager: Convert Tag Names to IDs

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, checks which tags already exist in KlickTipp, creates the missing ones, and returns a unified array of tag IDs — so you can reuse the same "get or create tags" logic across multiple automations.

How it works Accepts input tagNames[] (array of tag names). Splits the array into individual items and maps each name into a value field for matching. Loads your full KlickTipp tag list and matches by tag name. Creates tags that don’t exist yet. Combines existing + newly created tags and returns a single aggregated array of IDs.

Setup Instructions Credentials Configure your KlickTipp credentials in the KlickTipp nodes.

How to call this sub-workflow From a parent workflow, use an Execute Sub-workflow node and pass: { "tagNames": ["Tag A", "Tag B", "Tag C"] }

Output Returns aggregated tag IDs: { "tagIds": [123456789, 98765431, 999999999] }

Testing Test with a mix of existing and new tag names. Confirm new tags appear in KlickTipp and the output contains all expected IDs. Use tagIds[] in your parent workflow (for example, when updating or tagging contacts).
