Hey @André Sousa, we have some examples here for Kafka
https://docs.pactflow.io/docs/examples#consumers for JS and Java
https://docs.pactflow.io/docs/examples#providers for Java
We also have a recipe for Kafka here https://docs.pact.io/recipes/kafka#schema-registry-json-provider
Hope this helps indirectly answer your question

04/04/2022, 6:21 PMThanks @Yousaf Nabi (pactflow.io). Its correct to interpret that this object MessageAndMetadata will be used by Pact to compare the message defined by the consumer against the one produced by the provider?

04/04/2022, 6:21 PMFor instance, this method:
@PactVerifyProvider("a product created event")
public MessageAndMetadata productCreatedEvent() throws JsonProcessingException {
ProductEvent product = new ProductEvent("id1", "product name", "product type", "v1", EventType.CREATED, 27.00);
Message<String> message = new ProductMessageBuilder().withProduct(product).build();
return generateMessageAndMetadata(message);
}
