How can I keep track of API token expiration

Question

User1122679459 posted

Hi,

I'm working with an API that returns an access token and an expiration of 60 minutes. I created a @functions that returns the token but I can't figure out how I can keep track when the token expires.

So in my application, how can I keep track of when it expires? ...then I can just request another one.

This is the json the api returns:

{
    "token_type": "bearer",
    "expires_in": 3600,
    "refresh_token": "xxx",
    "access_token": "xxx"
}

It is up to the client to read the token expiration and request a refresh or a new access token.  It is not clear why you are unable to read the access token expiration and compare the token expiration to the current DateTime.

Hi Alvin,

If you'd like to trace the status/expiration of your access token in web application, you can create and run a web worker in the background, which could perform tasks without interfering with the user interface.

After you retrieved the token. you can start a timer based on expiration of token by using setTimeout() method, and request another one via refresh_token before it reaches expiration time.
