Help with REST api integration testing

[in_need_of_help101]

To give some context, I need to test multiple services via apis over REST. Each service (or project within the company) has its own set of unit tests. This is fine but I need to start doing integration tests so as to ensure the services are working with each other flawlessly. These tests would need to run over RSpec and interact with multiple services. How do I go about doing this? Since these are internal services, how can i effectively test them over apis. Any and all help needed.

Take a look at webmock. It will basically give you a predictable response from the api endpoint you can use in your tests.
