How to rate limit API access based on request header value in AFD (Azure Front Door)? For sample, the request contains header called "idKey" and the value is unique to customer. For each customer, they should be able to access only 100 req/min. More than that they should receive 429 (Too Many Requests) response status code. We have set up multiple app-services (region wise) behind the AFD.

    Azure Front Door does not have any API throttling capabilities, it is designed to be an edge endpoint for sites with a global footprint. If you are looking for an Azure solution with native API throttling, take a look at Azure API Management.
