Automate Personalized WhatsApp Campaigns with KlickTipp & n8n

What This Automation Does

This workflow starts by getting events from KlickTipp about subscribers joining campaigns.
Then it sends personal WhatsApp message templates that include names, products, and discount links.
It watches replies to catch “STOP” messages to let users opt out.
If a person says “STOP,” it sends a helpful reply pointing them to support.
The system adds or removes the person from KlickTipp lists based on their WhatsApp answers.
It blocks automated replies so messages do not loop forever.

The result is less manual work and better message timing that fits what users want.
The whole process keeps subscriber lists neat and helps marketing get better sales and happier customers.

Common Situations and Handling Steps

Phone Number Formatting

Incoming phone numbers may start with “00”.
This workflow replaces “00” with “+” for WhatsApp API formats.
Make sure numbers saved in KlickTipp follow this or messages may fail.

Opt-Out Handling

User messages with different cases or spaces around “STOP” are recognized.
The Switch node checks the start of the cleaned lowercase text for “stop” to catch opt-out.

Message Loop Prevention

The workflow filters out automated replies like WhatsApp system notifications.
This stops endless triggering of message sends and auto-responses.

API Errors

Errors can come from wrong template names or bad credentials.
Check credentials and template names carefully if errors appear in n8n executions.

Customizations

• You can change WhatsApp templates named in the WhatsApp nodes to fit new campaigns.
• Add extra custom fields from KlickTipp in the template placeholders to make messages more personal.
• Modify the stop-word detection in the Switch node to check for other opt-out keywords.
• Include an Email Send node to follow up by email if subscribers do not use WhatsApp.
• Segment or tag subscribers in KlickTipp automatically based on their WhatsApp interaction for better lists.
