Automated QR Code Generation via Webhook
detail.loadingPreview
Instantly generate QR codes on demand by sending data to a webhook. This workflow automatically processes incoming requests and returns the generated QR code image.
About This Workflow
This n8n workflow provides a streamlined solution for dynamic QR code generation. It leverages a webhook trigger to receive data, which is then used to query an external QR code API. The generated QR code image is then returned directly to the requester. This allows for real-time creation of QR codes for various applications, from product information to event tickets, without manual intervention. The workflow is easily configurable, allowing adjustments to webhook paths, QR code size, and response handling.
Key Features
- Real-time QR Code Generation: Create QR codes on the fly based on incoming data.
- Webhook Integration: Easily trigger QR code generation from any application or service that can send HTTP requests.
- Configurable QR Code Size: Adjust the dimensions of the generated QR code image as needed.
- Extensible Workflow: Modify the workflow to save QR codes, send them via email, or integrate with other systems.
