Hey @m.nagarajanbtech,
For user pye00ENcRburPJiUwhmnjg they do not exist in your Zoom account.
For user rK1JcLSzRC-q4F1iL1f4-Q they also do not exist in your Zoom account.
What are you passing into the userId path? The userID or the email? How are you getting the userId / email to make the Create Meeting API call?
Thanks,
Tommy
