Overview
This node is designed to query records from a data source identified by a unique token. It is useful in scenarios where you need to retrieve specific entries or datasets from a multi-dimensional table or database using an application token as the key identifier. For example, it can be used to fetch user data, transaction logs, or any structured records stored within a system that supports querying via such tokens.
Properties
| Name | Meaning |
|---|---|
| app_token | The unique identifier of the multi-dimensional table from which to query records |
Output
The output consists of JSON data representing the queried records from the specified data source. Each item in the output corresponds to a record retrieved based on the provided app_token. The structure typically includes fields and values relevant to each record in the multi-dimensional table.
If the node supports binary data output, it would represent attachments or files associated with the records, but this is not explicitly indicated in the provided code snippet.
Dependencies
- Requires an API or service endpoint capable of handling queries against the multi-dimensional table identified by the
app_token. - Needs proper authentication credentials (such as an API key or token) configured in n8n to authorize requests.
- Relies on internal modules for routing actions and fetching list data (
./actions/router,./transport/getList).
Troubleshooting
- Common Issue: Invalid or missing
app_tokenleading to no data returned or errors.- Resolution: Ensure the
app_tokenis correctly set and corresponds to an existing data source.
- Resolution: Ensure the
- Error Messages: Errors may occur if the API service is unreachable or credentials are invalid.
- Resolution: Verify network connectivity and confirm that authentication credentials are properly configured in n8n.
- If the node returns empty results unexpectedly, check if filters or query parameters are correctly applied (if applicable).
