In TRTH we are using the following requests:
Can you please give a short note what requests are meant to replace these TRTHv1 requests in DSS?
Can you please further advice if there are special permissions needed to test this requests? At the moment when we are running the Postman or Java examples we get 403 HTTP replies and the messages like this:
"message": "No permission for template \"TimeSeriesReportTemplate\"."
There are tutorials that explain how to retrieve the TRTH data you listed, via the REST API (which is, in fact, through DSS). More specifically, tutorial 4 is for Tick data (i.e. Times&Sales), tutorial 6 is for Intraday bars, and tutorial 7 is for EoD. These tutorials give all the details, including the workflow, requests, and responses.
And yes, you do need special permissions to access TRTH data via the REST API. From what you write it seems you do not have these permissions. Please refer to your account manager for this.
