To use Filescan integration in n8n, start by adding the HTTP Request node to your workflow canvas and authenticate it using a predefined credential type. This allows you to perform custom operations, without additional authentication setup. Once connected, you can make custom API calls to Filescan to query the data you need using the URLs you provide, for example: after establishing the connection, you can use the HTTP Request node to create, update, or retrieve records in Filescan. For example, to create a new entry, send a POST request to the appropriate endpoint with the necessary data in the body. Similarly, to update an existing record, use the PATCH method and supply the record ID along with the updated information.
