n8n has introduced a new feature that allows users to perform custom API actions for existing nodes, enhancing the platform's flexibility in creating custom workflows. This feature enables users to leverage the core HTTP Request node with existing credentials, eliminating the need for additional authentication setups when accessing more operations than those currently supported by the nodes' APIs. For instance, if an operation is not supported by the Airtable node, users can utilize their existing Airtable credentials within the HTTP Request node to execute any API call permitted by Airtable's API. This update aims to streamline the process of connecting multiple products and data sources in n8n's automation and low-code environments.
