Resource: ValidateError
A validation error identifies an issue in an XML or CSV metadata file that may cause an uploaded package that includes the file to fail. Note: You would upload the package via the Web, Aspera, or SFTP. The API call enables you to confirm that the metadata file is valid before uploading the package. See the YouTube Help Center
for more information about uploading content, including metadata files, to YouTube.
