I try to use the first api method - https://resellers.pipedrive.com/api-doc/#/subscription/getSubscriptions.
When I was testing it on that page (using “Try it out”) all works as expected.
But when I make curl request in php, than get 401 (unauthorized) or 500 error.
And I noticed that it checks cookies. When I launch it on browser where cookies are set, then all ok. But like I said on server side it becomes problematic.
