Hello @Upendra ,
Welcome to Microsoft Q&A Platform. Thank you for reaching out & hope you are doing well.
Please find the answer to your query below:
Is it possible to implement Rate limiting using Azure application gateway and WAF for REST APIs hosted in App service?
Unfortunately, Application Gateway WAF does not have a way to rate limit incoming connections.
Rate-limiting, geo-filtering, and Azure managed Default Rule Set rules are supported only with WAF on Azure Front Door.

Currently, you can only configure a WAF rate limit rule on Azure Front Door:
