Retrieving activities for a date range

[Philippe Gauvin]

I must be missing something but it seems I can't retrieve all activities for a date range. I can only specify a before OR after parameter. Is that correct? Any trick?

[Paul Mach]

There are two options.

1. use the "before" parameter and then a per_page of 100 or something. Assuming you'll have less than 100 activities in your range.

2. use "before", get 30 activities, if the last one isn't out of your range, do another request setting the before parameter as the start_date of the last activity. This will effectively give you the next page. Continue until you have all you need.

Note that the max value for per_page appears to be 200 (determined by trial and error).

No need for trial and error, it's in the documentation http://strava.github.io/api/#pagination

I've written this code to get all activities for a date range. You can modify it for your Programming language:

        /// <summary>
        /// Gets all the activities recorded in a specified period of time.
        /// </summary>
        /// <param name="after">Date after the activity was recorded.</param>
        /// <param name="before">Date before the activity was recorded.</param>
        /// <returns>A list of activities that was recorded between 'after' and 'before'.</returns>
        public List<Activity> GetActivities(DateTime after, DateTime before)
        {
            List<Activity> activities = new List<Activity>();
            int page = 1;
            bool hasEntries = true;

            while (hasEntries)
            {
                List<Activity> request = GetActivities(after, before, page++, 100);

                if (request.Count == 0)
                {
                    hasEntries = false;
                }

                foreach (Activity activity in request)
                {
                    activities.Add(activity);

                    if (ActivityReceived != null)
                    {
                        ActivityReceived(null, new ActivityReceivedEventArgs(activity));
                    }
                }
            }

            return activities;
        }

        /// <summary>
        /// Gets all the activities recorded in a specified period of time.
        /// </summary>
        /// <param name="after">Date after the activity was recorded.</param>
        /// <param name="before">Date before the activity was recorded.</param>
        /// <param name="page">Page of activities. Default value is 30.</param>
        /// <param name="perPage">Number of activities per page.</param>
        /// <returns>A list of activities that was recorded between 'after' and 'before'.</returns>
        public List<Activity> GetActivities(DateTime after, DateTime before, int page, int perPage)
        {
            String getUrl = String.Format("{0}?after={1}&before={2}&page={3}&per_page={4}&access_token={5}",
                Endpoints.Activities,
                DateConverter.GetSecondsSinceUnixEpoch(after),
                DateConverter.GetSecondsSinceUnixEpoch(before),
                page,
                perPage,
                Authentication.AccessToken);
            String json = WebRequest.SendGet(new Uri(getUrl));

            return Unmarshaller<List<Activity>>.Unmarshal(json);
        }
