Quick question about retrieving high-volume interaction metrics via the /api/v2/analytics/interactions/summary endpoint. We are hitting a 422 Unprocessable Entity error when requesting data spans exceeding 30 days with granular segment filters.
Our integration uses the standard OAuth2 client credentials flow and SDK version 2.1.0. The payload size remains well under the documented limits, yet the server rejects the request immediately.
Is there a hidden cap on segment cardinality for summary reports that is not documented in the API specs?
