The Headless API allows you to initiate the import flow programmatically. For example, you may start a Dromo import automatically whenever a file is uploaded to an SFTP server, emailed to you, stored in Google Drive, shared in Slack, or in response to any of hundreds of other events. If there are any errors during the flow (for example, a column cannot be matched automatically or a data validation fails) you are provided a URL where you can direct your user to fix the issues. If there are no errors, the import succeeds automatically and the user does not need to be involved.
