I am integrating constant contact api to my site . but auth redirection not working i first give http://localhost and dont get then i use 127.0.0.1 and changed my virtualhost setting . not working returning "'Invalid redirect. and Please close the window to return to your application. '"
Thank you for reaching out to Constant Contact API Support.
The redirect URI is used to authenticate the application with Constant Contact, so the value that you give us when making an authorization call needs to match what is stored for the application in your Mashery developer application.
