Aha
Aha! connects with OAuth 2.0. The end user enters their Aha! subdomain, then signs in.
Install the Aha integration
Install Aha from Available integrations in each environment you connect accounts from.
Use your own Aha OAuth app (optional)
Truto ships an Aha OAuth app, so OAuth 2.0 works without any setup. To show your own app on the consent screen instead, create an OAuth application in Aha!, register the redirect URL below, and set the app's Client ID and Client Secret on the installed integration. See Overriding OAuth credentials.
