API Connection to V13

/rest/v11_20/oauth2/token for version 13.0 with body:

{
"grant_type":"password",
"client_id":"sugar",
"client_secret":"",
"username":"{{usr}}",
"password":"{{pwd}}",
"platform":"base"
}

{{usr}} and {{pwd}} contain your user and password.

You can use mobile instead of base also.

See https://support.sugarcrm.com/Documentation/Sugar_Developer/Sugar_Developer_Guide_13.1/Integration/Web_Services/#Versioning for the actual versions until 13.1.

I am using Postman Authorization but cannot set the Base. My Auth to V11 works fines 

You can set your own API platform in asmin - Configure API platforms.

If you use "base" the user with the same userid will be cicked off from the UI when you use the API. Just use the existing "integration" or create a new one.
