We can easily run performance tests against Soap/Rest web services by using JMeter. REST web services uses the HTTP request method with most popular protocols like : GET and POST.
The responses return status codes indicating success or failure, along with any applicable headers, and JSON representing the affected fields (or nothing) in the message-body. In this example below, we use OpenWeatherApi for web service test. For detailed information for the api, please visit the site: http://openweathermap.org/api
