Quality API CSAT interaction_id mismatch

Pulling CSAT responses via GET /api/v2/quality/evaluations but the interaction_id doesn’t match the conversation ID from the Analytics API. The survey was completed and the evaluation exists. Here is the JSON payload for a single response. Why is the ID different?

{
 "id": "8f7d6e5c-4b3a-2109-8765-4321abcdef01",
 "interactionId": "a1b2c3d4-e5f6-7890-1234-567890abcdef",
 "surveyResponse": {
 "score": 5
 }
}
