I am trying to create a SmartApp with API access using OAUTH. Reading the documentation here: OAuth Integrations | SmartThings Developers.
It states: " From the project creation page on Developer Workspace, select API Access . However, when I go through that, there is no API Access. It only has “Device Integration” and “Automation for SmartThings App”.
How can I get access to create an API integration app started?
