Hello @shwetha.krishnaiah02,
DSS REST API connections are not a persistent, they are request/response, there are many good resources online that describe REST API paradigm in brief, for example What is REST API and how does it work
The limits that are very important to DSS REST API developer are how many of the specific template request can be submitted in parallel, and how many of them are going to be processed. Concurrent extraction request limits and concurrent extraction processing limit information can be found in DataScope Select Best Practices & Fair Usage Policy Guide
Hope that this information helps
Thanks @zoya faberov , So a single DSS user can make multiple connections with the same IP address or different IP address- there is no limitation on connections made however the limitation exists only specific report templates and concurrent request made as per best practice guide.
Thank you
