@Radha_S,
Good Day! Welcome to the community!
I think it is not possible as per the API docs, mean while let me check with the product team and get back to you at the earliest
Step2 : API call to check the status of the data export request and get a signed link to download this data as a csv file. Use the id that you received from the API call made in Step1.
Within this csv file, you can refer to the columns conversation_alias and user_id
Note:
You can pass a start & end timestamp in UTC timezone to the API call in step1 to get the list of users & conversations for a specific time period.
This specific report type allows you to export data only for a 24hr time period with each API call. You might have to make multiple API calls to export data for multiple days
