Client has already set up all his schedules but he would like to retrieve the extracted files using the the REST API, is it possilbe? Can you give an example?
this is indeed possible.
There are also samples in the C# example application (which also shows the HTTP requests and responses, and is described in the Quick Start), under section Scheduled Extractions, see the samples Get Completed By Date Range, Get Completed By Date Range By Schedule Id, ExtractedFiles: Get Latest and ExtractedFiles: Get Changes. These are all variants that accomodate slightly different workflows, but will all retrieve data that was generated by pre-existing schedules.
Tick History Client want their GUI custom extractions output files downloaded to their system automatically with no manual intervention. As Tick History does not support FTP, looking for a way to do the same through API
