Problems with Subscriptions: No activities reported for a subset of users.

[PawelRTE]

Hello,

We have a web app consuming Fitbit WebAPI activities which uses "Server" style OAuth 2 or Authorization Code Grant Flow coupled with subscriptions. We have configured subscriptions a long time ago and it worked great for all of our users, save the occasional, unexplained 409 error  during the Fitbit authorization phase.

Recently, we've observed that even though subscription notifications of activities are received, like so:

{
  "_json": [
    {
      "collectionType": "activities",
      "date": "2019-07-08",
      "ownerId": "123ABC",
      "ownerType": "user",
      "subscriptionId": "12345"
    },
    {
      "collectionType": "activities",
      "date": "2019-07-08",
      "ownerId": "456DEF",
      "ownerType": "user",
      "subscriptionId": "67890"
    }
  ]
}

the actually retrieved data has goals and summary section but no activities:

{
  "activities": [

  ],
  "goals": {
    "activeMinutes": 30,
    "caloriesOut": 2184,
    "distance": 5,
    "floors": 10,
    "steps": 10000
  },
  "summary": {
    "activeScore": -1,
    "activityCalories": 7,
    "caloriesBMR": 499,
    "caloriesOut": 506,
    "distances": [
      {
        "activity": "total",
        "distance": 0.04
      },
      {
        "activity": "tracker",
        "distance": 0.04
      },
      {
        "activity": "loggedActivities",
        "distance": 0
      },
      {
        "activity": "veryActive",
        "distance": 0
      },
      {
        "activity": "moderatelyActive",
        "distance": 0
      },
      {
        "activity": "lightlyActive",
        "distance": 0.04
      },
      {
        "activity": "sedentaryActive",
        "distance": 0
      }
    ],
    "elevation": 0,
    "fairlyActiveMinutes": 0,
    "floors": 0,
    "lightlyActiveMinutes": 3,
    "marginalCalories": 3,
    "sedentaryMinutes": 0,
    "steps": 105,
    "veryActiveMinutes": 0
  }
}

Note the empty activities stanza. Our users do have activities they track, like swim or bike that have shown up in the past, but for s subset of our users no activities has shown up when subscriptions were being retrieved. When we requested those users to check activity log on Fitbit, it showed Bikes and Swims activities.

Any idea what might be going wrong?

Thank you,

Hi @PawelRTE,

I'm sorry to hear that you're not seeing activities from users despite receiving a notification for it.

So that I can investigate further, can you private message me your Client ID and the User ID(s) of which you are seeing activity notifications for, but no activities are logged?

Let me know if you have any questions in the meantime. Thanks!
