This article explains how many times a user can be redirected using Actions in an authorization flow.

• This has changed from Rules as the limit with Rules was only once, as noted in Redirect Users from Within Rules. 
  
  You can redirect a user once per authentication flow. If you have one rule that redirects a user, you cannot invoke a second rule to redirect the user at a later time.

• Actions
• Redirections

Actions can redirect multiple times in an authentication flow. There is no hard limit on the number of times. However, the following restrictions apply:

• Each unique URL can be redirected only once per authentication flow
• Only one redirection per Action
