On 06/25/2026 we began seeing a large number of 500 Internal Server Errors from the Analytics API. The failures are concentrated on the segments endpoint:
https://api.appstoreconnect.apple.com/v1/analyticsReportInstances/{id}/segments?limit=200
Summary of the issue
Start time: 06/25/2026 (first observed) Endpoint: /v1/analyticsReportInstances/{id}/segments Query used: ?limit=200 Error: HTTP 500 Internal Server Error Scope: massive number of errors across multiple requests and report instances Frequency: sustained and repeated since first occurrence
Examples and evidence
Large volumes of 500 responses from the segments endpoint beginning 06/25/2026 Logs show repeated failures for multiple report instance IDs (e.g., analyticsReportInstances/xxxxxx/segments) Timestamps and request IDs available in our logs for diagnosis
Steps already taken
Verified request format and parameters (limit=200) Retried requests with smaller page sizes and different limits Confirmed authentication and API credentials are valid Checked for known outages from App Store Connect status pages (no matching incident found at time of first detection)
Requested next actions
Please investigate server-side errors for the segments endpoint beginning 06/25/2026 Provide guidance on whether this is a transient outage or a breaking change If possible, share an expected timeline for a fix or any recommended workarounds
