Template → List Template Layers
AI-generatedOverview
The node "Templated" automates the generation of images and PDFs by interacting with a templating service. Specifically, the "List Template Layers" operation retrieves all layers associated with a given template ID. This is useful when you want to inspect or manipulate the individual components (layers) of a template before generating final output files.
Common scenarios include:
- Fetching template layer details to dynamically modify or populate them.
- Validating the structure of a template before batch processing.
- Integrating template layer data into workflows that generate customized images or documents.
Example: You have a template for a marketing flyer and want to list all text and image layers so you can programmatically update their content before exporting the flyer as a PDF.
Properties
| Name | Meaning |
|---|---|
| Template ID | The unique identifier of the template whose layers you want to retrieve. This is required. |
Output
The node outputs JSON data representing the layers of the specified template. Each item in the output corresponds to a layer within the template, typically including properties such as layer type, position, content placeholders, and styling information.
If the node supports binary data output (e.g., generated images or PDFs), it would be included alongside the JSON, but based on the provided code snippet, the focus here is on JSON output describing template layers.
Dependencies
- Requires an API key credential to authenticate requests to the templating service.
- The base URL for the templating API must be configured in the node credentials.
- The node sends HTTP requests with JSON payloads and expects JSON responses.
Troubleshooting
- Missing or invalid Template ID: Ensure the Template ID property is correctly set; otherwise, the API call will fail.
- Authentication errors: Verify that the API key credential is valid and has necessary permissions.
- Network issues or incorrect base URL: Confirm the base URL in credentials points to the correct templating service endpoint.
- Unexpected response format: If the API changes, the node might not parse layers correctly; check for updates or API documentation changes.
