How to download a single file from Google Drive

In the API Source Component, we’ve chosen the API Connection Manager. Next, we need to configure the remaining properties of the component to download the single file from Google Drive.

1. Choose the Download a file endpoint from the “Select Table/Endpoint” dropdown menu.
2. To access detailed API documentation for downloading files, you can click on the following link: Help for: Download a File.
3. Please choose a File ID from the drop-down menu to indicate which file you wish to download. This is an essential parameter for the download process.
4. Please indicate the desired filename for the file being downloaded by setting the FileName parameter.
5. If you intend to replace the local file with the one being downloaded, please select the ‘AlwaysOverwrite‘ option from the dropdown menu labeled ‘FileOverwriteMode‘. Alternatively, you can choose ‘FileIfExists’ or ‘SkipIfExists’ based on your specific needs.

Please refer to the sample screenshot below.
