I am building an oauth app to connect to Basecamp 3 API using PHP and following the documentation here.
https://github.com/basecamp/api/blob/master/sections/authentication.md
The request authorization url works fine
https://launchpad.37signals.com/authorization/new
but the token url produces a page not found
https://launchpad.37signals.com/authorization/token
I contacted Basecamp but didn't get a response. They do say they don't prioritize suppose issues with the API because so few of their customers use it.
Any ideas on what the correct url for getting tokens would be?
