Strava API Occasionally Returns Incomplete Activity Data

I’m working with the Strava API and have noticed inconsistent responses when retrieving activity data.

What I’m seeing:

  • API requests generally work as expected.
  • Some activity responses occasionally contain missing fields or incomplete data.
  • Repeating the same request later may return the expected information.
  • The issue seems more noticeable when requesting several activities in a short period.
  • Authentication and access tokens appear to be valid.

I’ve checked my request parameters and response handling but haven’t been able to identify the cause. Has anyone experienced inconsistent or incomplete responses from the Strava API, and are there recommended practices for handling this reliably?

You didn’t answer in your first post about that:

Yes, I can provide more detail. The missing data is not consistent across every request, which is what has made this difficult to narrow down. For example, I have seen an activity response where some of the normal activity fields are present, but fields that are normally returned for the same type of activity are missing or incomplete. The same activity ID can sometimes return the expected structure when I request it again later, so I’m trying to determine whether this is related to the API response itself, timing, or something in how I’m making multiple requests.

You could reveal a response json where data was missing.
