Multiple trackers handling and subscriptions

[derailed]

Hi,

   With the new support for multiple trackers for a given user, I am wondering how does this affect the api and push notifications. Say a user has two devices A and B. If my application receives push notifications for this user how can I determine which device is reporting activity?

  Similarly if want to fetch the latest sleep data for device A how would one formulate this query?

  Subscription API. I've setup my users for push notifications but it seems that when I subscribe for all events the notification collection type always report "activities". So I have no clue which activity actually reported new data ie hr, steps, sleep?? - I understand I can add subsriptions for each individual activity but I would like to be able to say notify me when a new activity is reported and expect the notification to contain a clue as to which activity actually changed. Lastly if a user update her profile it doesn't seem that this event triggers a notification?

Activity type basically means one of following things changed for user:

steps, calories, elevation, distance. 

When you get notification with activities type I'd just suggest to make activities request for that date.

For sleep you'll get different notification type.

Makes sense. Thank you! - Can you also answer the other questions that are part of the original post ie tracking push notifications when multiple devices for a given user are at play.

Thanks!

I'm confused with your last post.

To answer this question:

[ Lastly if a user update her profile it doesn't seem that this event triggers a notification?]

Yes this is correct. We do not send push notifications when user updates his profile.

Yes this is correct. We do not send push notifications when user updates his profile.

Sorry. That was indeed confusing. Let me rephrase...

Say a user has 2 trackers A and B. User registers with fibit for push notifications.

1) How do I know which of the 2 devices trigger the notification? ie steps activity was collected for device A or B.

2) Once I get a notification. How does one request metric data for a given device?

ie I want to get steps/sleep/hr for device A or B.

I am not seeing in the api where one would request steps data for a specific device. What am I missing?

[ibahdanau]

This is currently not possible.

Thanks for the reply. Can u elaborate? This feature is available in the dashboard. I can see metrics reported for each of my devices. Is this feature coming in the API or will not at all be supported?

[ibahdanau]

We currently have no plans on supporting it. It may change in future though. No promises or estimations yet.

[derailed]

Woa! This is surprising. Just to make sure we're on the same page here. 

Are you saying that this announcement https://blog.fitbit.com/sync-multiple-trackers-to-your-fitbit-account-with-multi-tracker-support/ will NOT be supported or planned to be supported by the API?

Sorry to beat this dead horse if so.

Thanks!

I'm saying that there is no plans for API push notifications to be saying what device the push notification belongs to. 

I'm also saying that it may change. I just don't want to give any promises.

[derailed]

Understood - So to be clear,  since there are 2 separate use cases here: Outside of the push notification is there a way to request a given metric for a given device then? Or is this not supported either?

Ie Fetch sleep data for device A or retrieve steps data for device B?

@derailed How do you see the data in the dashboard separately for your two trackers? (The whole point of Fitbits multi-tracker support is that you only wear one Fitbit at a time and the data is combined automatically so you only see one set of data for all of your trackers.)

I certainly can't find any way to see just the data for one of my trackers linked to my account through the dashboard.

The device sync itself doesn't trigger the notification—the change in data triggers the notification. A change in data could come from a tracker or a manual log. The Subscriptions API doesn't currently give a reason for the change in data.

Fitbit intelligently combines data from multiple devices and sensors. The data is available in a unified manner, not per device.
