How many days are the data available in the API /webinars/registrants?

I am using the API ‘GET /webinars/{webinarId}/registrants’, but I found that I am unable to retrieve data that is older than 90 days! It shows a message saying the Webinar does not exist, but it does exist, and I can access it through other endpoints. Can someone help me with this?

If you could also tell me, how many days the data is available for:

  • Webinars
  • Registrants
  • Participants

Thank you very much in advance."
