Recent Strava API Stability Issues: 400 Errors & Sync Failures

Hey everyone,

We’re seeing some weird behavior with the API for our app, Run The Date, and wanted to see if others are experiencing the same:

  1. OAuth 400 Errors: Random "Bad Request" failures when exchanging the authorization_code for tokens. Redirect URIs match, but it’s failing intermittently for new users.
  2. Missing Activities: Even with per_page=200, the /activities endpoint is occasionally missing data or stalling during the sync process.

Can someone help with that?
