Zoom webhook to salesforce integration

I want to whenever someone registers for a meeting the data should b stored in my salesforce org,
As directed in the documentation i created webhook only app, added the event and event type(meeting) but i am unable to validate my endpoint url(made site on the salesforce ,allow the apex class that is having my post request ie used for validating ) still facing issue what is wrong in my procedure please help.
also if there is any other alternative please do let me know, Thank you in advance for any help and suggestion

Ensure your endpoint URL is HTTPS and accessible externally for Salesforce webhook validation. Consider using Salesforce Platform Events or integration tools like Zapier for reliable data integration if webhook setup persists as an issue.
