Does Fitbit subscription still ping when an access token is expired?

[TATeam]

I wait for a ping to be received and once I receive the ping I check if I need to renew the access token. However if a user does not sync their data for a while and then syncs after their access token has expired would I still receive the ping and be able to refresh their access token or do I need to constantly refresh their token manually without waiting for a ping.

Thanks!

Hi @TATeam,

As long as the user has not revoked access to your application, you should still receive the subscription notifications when a user has updated their data.  The refresh token should not expire.  When you get a notification (ping), you should follow these steps:

1. Respond to the notification within 3 seconds
2. Exchange the refresh token for a new access token/refresh token pair
3. Fetch the updated data
