Using json schema within pact for contract testing

I started experiencing pact a while a ago, and I'm wondering if any of you guys has any idea if pact support Json schemas!

I'll describe the flow. suppose you have two microservices:

• Microservice A - the consumer
• Microservice B - the Provider

The provider exposes an Api - basically a POST request and expects an explicit json body payload (some field are required). Let's say:

{
  "id": "123",
  "name": "Bob"
}

both id and name are required properties.

Suppose now that the provider changed it's behaviour to expect the same json payload but with an additional property:

{
  "id": "123",
  "name": "Bob"
  "extraProperty": "newProperty"
}

My question is is there anyway to detect such breaking contract using pact framework? if not what do think is the best way to test such scenario.

Thanks for the help.
