Get Auth Token - HTTP request on a need basis

[HarishDe]

Hi Everyone 

Kindly note the below points

1. Get Auth Token is a simple HTTP request with a user name & password sent as a POST req.
2. The Generated Auth Token is valid for 1 Hour
3. I would like to store the ID generated in the datastore whereby other scenarios can use the ID for performing various CRUD operations.
4. If Expired , then I would like to wait for 1 min

Based on the above points I would like to implement a scenario as per the attached diagram. 

Can someone let me know if this is possible ? 

Kindly also let me know if there a better alternative for the same ? 

Thanks

Harish
