i am creating a App, the App url is https://developer.zapier.com/app/115016/version/1.0.0.
i have configure the OAuth2. i have set all necessary url. like Authorization URL: https://oauth.flightbycanto.com/oauth/api/oauth2/authorize.
now go to last step "Test your Authentication". i click 'Sign in to Zapier on Dev' button, it open a dialog, but the address bar show address as: https://zapier.comhttps//oauth.flightbycanto.com/oauth/api/oauth2/authorize?client_id=9b0aad2e340b4496a176e62a65c99ff1&state=1597659044.513948265019&redirect_uri=https%3A%2F%2Fzapier.com%2Fdashboard%2Fauth%2Foauth%2Freturn%2FApp115016CLIAPI%2F&response_type=code
please notice here! the url is begin with: https://zapier.comhttps//oauth.... so it will not open a valid address.
How have you configured your URI? I’ve never seen this before, are you sure you haven’t added this somewhere by mistake?
