Gravity Forms Submission Processing and Dynamic KlickTipp Tagging - n8n Workflow

Marketing professionals relying on KlickTipp for sophisticated email segmentation and campaign management.
Businesses using Gravity Forms for lead generation and detailed customer feedback collection.
n8n users seeking advanced data transformation and flow control examples utilizing the Set and Merge n8n node types.
Developers looking for specialized n8n templates for robust CRM integration that includes dynamic tag management.

This expert n8n workflow solves the complex challenge of synchronizing data between a dynamic feedback form (Gravity Forms) and a marketing automation platform (KlickTipp). Standard integrations often fail when data requires extensive cleaning—like converting phone number formats, translating dates into UNIX timestamps, or handling dynamic tags derived from form input. This robust n8n workflow handles all necessary data manipulation using specialized n8n node configurations.

Using this n8n automation ensures high data fidelity and efficient campaign segmentation within KlickTipp. It uses an advanced conditional logic approach to check if required tags already exist in KlickTipp; if not, the n8n workflow creates them instantly before applying them to the new subscriber. This saves time and ensures a seamless user experience starting from the moment the user interacts with the Gravity Forms submission and continuing into the backend marketing system.

The entire process is initiated by an efficient n8n trigger, the Webhook n8n node, which captures form data:

1. Trigger and Ingestion: The New submission via Gravityforms n8n trigger node starts the n8n workflow upon receiving a POST request containing the form data.


2. Data Transformation: The Convert and set feedback data n8n node immediately executes crucial cleaning and formatting logic. This includes using complex expressions to convert phone numbers to a numeric-only international format and transforming date fields (like birthdays) into a Unix timestamp (in seconds), ensuring compatibility with the KlickTipp API.


3. Contact Subscription: The Subscribe contact in KlickTipp n8n node uses the cleaned data (email, name, custom fields) to subscribe the contact to a specified KlickTipp list.


4. Parallel Tagging Preparation: After subscription, the n8n workflow branches into two paths. One path extracts an array of desired tags from the Gravity Forms input (Define Array of tags from Gravityforms). The second path uses the Get list of all existing tags n8n node to retrieve all current tags in KlickTipp.


5. Comparison Logic: The Merge n8n node combines these two lists using an SQL-based comparison to determine which of the required tags already exist and which are new, producing an item for each required tag with its existence status.


6. Conditional Tagging: The Tag creation check n8n node acts as a switch. If the tag is found (true branch), the ID is aggregated and applied using the Tag contact directly in KlickTipp n8n node. If the tag is new (false branch), the n8n workflow executes Create the tag in KlickTipp first, then aggregates the new ID, and finally applies the tag using the Tag contact KlickTipp after trag creation n8n node, finalizing the contact record.

To deploy this comprehensive n8n workflow, follow these steps:

1. Importing the n8n Workflow: Copy the provided JSON data and paste it directly into your n8n instance via the 'New' > 'Import from JSON' option. This establishes the full structure of the n8n templates.


2. Configuring the n8n Trigger: Navigate to the New submission via Gravityforms Webhook n8n node. Activate the workflow to generate a unique Webhook URL. Copy this URL and configure your Gravity Forms notification settings to send data to this endpoint upon submission.


3. Credential Setup: Authenticate all KlickTipp n8n node instances. You will need to input your KlickTipp API username and password into the shared credentials.


4. Field Mapping Review: Critically review the Convert and set feedback data and Subscribe contact in KlickTipp n8n nodes. Ensure that the JSON path expressions (e.g., body['4'], body['1']) accurately reflect the field IDs from your specific Gravity Forms setup. Adjust the hardcoded listId and custom field IDs (field214512, etc.) in the Subscribe contact in KlickTipp n8n node to match your KlickTipp environment.

New submission via Gravityforms (Webhook): The starting n8n trigger. Configured for POST requests, it captures raw data submitted from the Gravity Forms plugin, initiating the n8n workflow.
Convert and set feedback data (Set): A critical n8n node for data hygiene. It uses JavaScript expressions to transform phone numbers (adding '00' prefix and removing non-numeric characters) and converts form dates into essential UNIX timestamp format for KlickTipp.
Subscribe contact in KlickTipp (KlickTipp): This specialized KlickTipp n8n node handles the primary CRM operation. It uses the cleaned data to subscribe the user and maps specific form fields to custom fields in KlickTipp (e.g., field214514 for webinar rating).
Define Array of tags from Gravityforms (Set): Collects potentially dynamic tagging information from multiple form fields and consolidates them into a single array for further processing by the n8n workflow.
Get list of all existing tags (KlickTipp): Fetches the current inventory of tags directly from the KlickTipp account.
Merge (Merge): This powerful n8n node uses a combineBySql operation to join the requested tags with the existing tag list, allowing the n8n workflow to determine, for each tag, whether it needs to be created or simply applied.
Tag creation check (If): A core logic n8n node that branches the workflow based on the exist boolean output from the Merge n8n node, ensuring no redundant tags are created.
Create the tag in KlickTipp (KlickTipp): Executed only for new tags. It dynamically creates the necessary tag structure in KlickTipp.

• Tag contact directly in KlickTipp / Tag contact KlickTipp after trag creation (KlickTipp): The final actions in this n8n workflow, applying the required tag IDs (either existing or newly created) to the subscriber via the contact-tagging resource.
