API rate limiting in Kong

We can limit the rate of an API for a given consumer. For example, GitHub limits clients to make 5000 requests per hour. After that, it throws an API rate limit exceeded error. We can add similar rate limiting constraints for our API using Kong's rate-limiting plugin.

We can enable it using this API: http://localhost:8001/apis/myapi/plugins, with POSTname, config.hour, and consumer_id as body parameters:

This API call is creating a rate limiting rule. The consumer_id is the id of the username johnd. This JSON response has an ID
