As mentioned on (https://developer.atlassian.com/cloud/confluence/security-overview/) following are three different Authentication available for Confluence:
Atlassian Connect JWT authentication
Atlassian Connect OAuth 2 JWT token exchange
Currently I am using first that is Basic Authentication for REST API requests. Can I use Atlassian Connect JWT authentication and Atlassian Connect OAuth 2 JWT token exchange for REST API request from my app or these two are only for Atlassian Connect app? What is Atlassian Connect App?
Thanks in advance.
