Could you tell me what exactly seems to be the problem please? I believe those items are explained here or is there something missing? 1.8 API Introduction
Long story short, you define parameters in environment (like url access_token etc) and then use those parameters in {{ }} in your calls, instead of providing cms address or access_token in each call
so let’s say
you had something like
192.168.0.11/api/layout
if you define url in the environment then you’d simply use
{{url}}/api/layout
similar for access_token in most calls headers, instead of trying to copy/paste in each time, you will want to have it defined in environment and then in headers:
If you’ve downloaded the collection from my guide then I believe most calls already have that this way - all you’d need to do is to define access_token, url and others in the environment.
