Overview
This node is designed to interact with a service that manages "Data Fields." Specifically, the "Get Data Field" operation retrieves information about a particular data field by its identifier. This can be useful in scenarios where you need to fetch metadata or details about specific fields within a contact or subscriber database, for example, to dynamically adjust workflows based on field properties or values.
Practical examples include:
- Fetching a custom field's details before updating it.
- Retrieving field metadata to validate input data.
- Using field information to conditionally branch workflow logic.
Properties
| Name | Meaning |
|---|---|
| Data Field | Select a data field from a list loaded dynamically or specify its ID manually using an expression. |
Output
The node outputs JSON data representing the details of the requested data field. This typically includes metadata such as the field's name, type, and possibly other attributes defined by the external service. The exact structure depends on the external API response but generally provides comprehensive information about the selected data field.
No binary data output is indicated.
Dependencies
- Requires connection to an external service managing data fields (likely via an API).
- Needs an API key or authentication token configured in n8n credentials to authorize requests.
- The node relies on internal methods for loading options and routing execution, which are part of the bundled source code dependencies.
Troubleshooting
Common issues:
- Selecting a non-existent or invalid data field ID may result in errors or empty responses.
- Authentication failures if API credentials are missing or incorrect.
- Network connectivity problems affecting API calls.
Error messages:
- Errors related to "field not found" indicate the specified data field ID does not exist; verify the ID or use the dynamic selector.
- Authentication errors suggest checking the configured API credentials.
- Timeout or network errors require verifying internet access and API endpoint availability.
