Anyway Pinnacle provides 2 repositories here https://github.com/pinnacleapi :
The one i’m trying to use ie api documentation https://github.com/pinnacleapi/pinnacleapi-documentation/blob/master/APIChangelog.md
And the swagger documenation https://github.com/pinnacleapi/openapi-specification
Is there a way to directly import the swagger from there into Postman?
