I am looing for an API though which I can export evaluation report. I tried below API but the output of that API is giving me the question ID and not the exact question we have build.
The EvaluationQuestionGroup and EvaluationQuestion objects and EvaluationScoringSet objects from GET /api/v2/quality/conversations/{conversationId}/evaluations/{evaluationId} appear to be comprehensive in their inclusion of questions and answers.
If you think there is data missing from the API response please log a ticket with Care.
You may have not noticed that there is an expand query parameter that you can set in GET /api/v2/quality/conversations/{conversationId}/evaluations/{evaluationId}. See API endpoint description here.
If you specify evaluationForm using the expand query parameters, the response will also include the questions contents/text.
