JWT Token - Consume REST POST API at client side

Question

I need to consume a REST API. RESTAPI will return an JWT token as a response  by calling REST POST method. I need to decode and validate the JWT token at my end and then redirect users to certain URL's accordingly based on token expiry time. I have a shared secret code and the Client ID of the service. If (token is expired)then redirect to loginpage  else redirect to the webapplication. I just need to consume the service. Hence i think  client side coding only will be enough to handle decoding and validation of token. I am implementing this in Sharepoint 2013  but normal c# code would cater to this too. Any technical advice on this would be greatly helpful. Lloking forward to your response. Thanks all.

Decoding and Token Validation should be handled at the server where the token is generated. The server where you request a JWT token should also provide a REST API to Validate Decode and Renew the token string.
