This n8n workflow orchestrates a multi-step customer engagement process that incorporates external event triggers and rate limiting to ensure effective communication and approval workflows. Starting from a manual trigger, it retrieves customer data, batches the processing, sends personalized messages via a messenger node, and waits for external approvals before continuing. The process includes creating unique approval URLs, sending messages to both merchants and clients, and managing delays to avoid rate limits. A key feature is the use of webhooks for external approvals, making it suitable for scenarios like purchase approvals, feedback collection, or multi-party confirmations. This workflow is ideal for automated, approval-based customer interactions that require external validation, ensuring smooth, controlled communication flow.
