Hey there 
!
Just so you know, the Xray REST API is your go-to for handling those heavy-duty or time-consuming operations. It’s got specific endpoints designed just for that.
So, your first step is to get your hands on the token. This is based on the Client Id and Client Secret of your assigned API Key. Once you’ve got that, you’re all set to make your requests to the Xray Cloud. Happy coding! 
Top right corner select 
& navigate to Apps.
From the left side menu look for "API Keys" under Xray Settings, and click it.
