Quality API interactionId returning null for CSAT surveys

NICE CXone API & Integrations

Trying to link CSAT responses back to specific voice interactions using the Quality API. I’m querying GET /api/v2/quality/surveys/interactions. The response returns the survey data, but the interactionId field is consistently null. I’ve verified the surveys are linked to the interactions in the UI. Here’s the payload :

{
 "id": "abc-123",
 "interactionId": null,
 "response": "5"
}

Is there a specific filter needed?
