Hey @wkhasintha,

Thank you for your question and welcome to the developer forum! First, I would check that you meet the prerequisites outlined in the API reference for the Add a Webinar Registrant endpoint.

If you meet those requirements, I would also check that your code is successfully renewing the token before it expires. Also, if you’re able to share any information about the code that is failing or how you’re making the call that will prove to be helpful in troubleshooting.

I hope that helps, let me know if you have any questions.

Thanks,
Max
