Overview
The "Mallabe Barcodes" node provides utilities to generate and scan various types of barcodes, including QR codes, UPC, EAN, and others. Specifically, the Scan Barcode operation allows users to scan a barcode or QR code from an image URL and extract the encoded data.
This node is useful in scenarios such as:
- Automating inventory management by scanning product barcodes from images.
- Extracting information from QR codes embedded in marketing materials.
- Integrating barcode scanning into workflows without manual intervention.
For example, you can provide a public URL of an image containing a QR code, specify the barcode type, and the node will return the decoded data from that barcode.
Properties
| Name | Meaning |
|---|---|
| Barcode Type | The type of barcode to scan. Options include: Code 128, Code 39, EAN-13, EAN-8, Interleaved 2 of 5, QR Code, UPC-A, UPC-E. |
| Barcode Image URL | Public URL of the image containing the barcode to be scanned. |
| Webhook URL (Optional) | Optional webhook URL to receive the scanned data asynchronously after processing. |
Output
The output JSON contains the result of the barcode scan operation. It typically includes the decoded data extracted from the barcode image.
If the node is configured to download the generated barcode image (not applicable for scanning), it can also output binary data representing the image file. However, for the Scan Barcode operation, the main output is the JSON with the scanned barcode data.
Dependencies
- Requires an API key credential for the Mallabe Barcodes service to authenticate requests.
- The node makes HTTP POST requests to the Mallabe Barcodes API endpoints to perform scanning.
- The input barcode image must be accessible via a public URL.
Troubleshooting
- Invalid or inaccessible image URL: Ensure the provided image URL is publicly accessible and points directly to an image containing the barcode.
- Unsupported barcode type: Verify that the barcode type selected matches the actual barcode in the image.
- API authentication errors: Confirm that the API key credential is correctly configured and has necessary permissions.
- Empty or no data returned: This may happen if the barcode is not detected in the image; try using a clearer image or different barcode type setting.
