Yesterday Strava sent out an e-mail to users, outlining a change that’s occurring almost immediately, regarding 3rd party apps and the way apps are allowed to access and process data from Strava. All of these changes impact what is known as the Strava API (Application Programming Interface). That’s the piece that lets your Garmin watch push your workout to Strava, and then lets an app like VeloViewer or others access your data.
There are countless apps that use Strava’s API, literally tens of thousands according to Strava. Some of these are tiny, some of them are massive. Virtually every company in the space uses Strava’s API, including Garmin, Wahoo, TrainerRoad, VeloViewer, Xert, and plenty more. It’s become the defacto data hub for millions of athletes, some 100m+ according to Strava’s press release.
