Overview
The node integrates with the CodeQR API to retrieve information about QR Codes. Specifically, the "Get" operation under the "QR Code" resource allows users to fetch details of a specific QR Code by its unique identifier. This node is useful in scenarios where you need to programmatically access QR Code data stored or managed via the CodeQR service, such as verifying QR Code details before processing or displaying them in an application.
Practical examples include:
- Retrieving metadata or status of a QR Code for validation.
- Fetching QR Code details to display in dashboards or reports.
- Integrating QR Code data retrieval into automated workflows for inventory, ticketing, or authentication systems.
Properties
| Name | Meaning |
|---|---|
| Authentication | Method of authenticating with the CodeQR API. Options: Access Token |
| QR Code ID | The unique identifier of the QR Code to retrieve. This is a required string input field |
Output
The node outputs a JSON array containing the details of the requested QR Code. Each item in the output array corresponds to the QR Code data retrieved from the CodeQR API. The exact structure depends on the API response but typically includes fields such as QR Code metadata, status, creation date, and other relevant attributes.
No binary data output is indicated for this operation.
Dependencies
- Requires an active connection to the CodeQR API.
- An API key or access token credential must be configured in n8n to authenticate requests.
- Network connectivity to the CodeQR service endpoint is necessary.
Troubleshooting
- Unsupported Operation Error: If the node throws an error stating the operation is not supported, verify that the "resource" and "operation" parameters are correctly set to "qrcode" and "get" respectively.
- Authentication Failures: Ensure the provided access token is valid and has sufficient permissions to access QR Code data.
- Invalid QR Code ID: Providing an incorrect or non-existent QR Code ID will likely result in an error or empty response. Double-check the ID value.
- Network Issues: Connectivity problems can cause request failures; verify network access to the CodeQR API endpoint.
