In this hands-on lab, you will have the opportunity to work with Confluent REST Proxy by using it to publish some messages to Kafka topics.

Challenge
Publish the Missing Records to the `inventory_purchases` Topic.
- Publish the records using an HTTP request to Confluent REST Proxy:
curl -X POST -H "Content-Type: application/vnd.kafka.json.v2+json" -H "Accept: application/vnd.kafka.v2+json" --data '{"records":[{"key":"apples","value":"23"},{"key":"grapes","value":"160"}]}' "http://localhost:8082/topics/inventory_purchases"- We can verify that the data is in the topic with a console consumer:
kafka-console-consumer --bootstrap-server localhost:9092 --topic inventory_purchases --from-beginning --property print.key=true -
Challenge
Publish the Missing Records to the `member_signups` Topic.
- Publish the records using an HTTP request to Confluent REST Proxy:
