IoT Core API with Java

Question

Hi everyone,

I am looking for information on how to disable or revoke the certificate of a thing in IoT Core and I have only found that it can be done from its API.

- Is it possible to modify the state of a thing from the java sdk?

- How can I, from java, communicate with the IoT Core API?

Regards.

Answer

Hi. In general, for any given API operation, there's a matching CLI operation and matching methods in each of our SDKs. For example, for the [IoT UpdateCertificate API operation](https://docs.aws.amazon.com/iot/latest/apireference/API_UpdateCertificate.html):

* CLI: https://docs.aws.amazon.com/cli/latest/reference/iot/update-certificate.html
* Python boto3: https://boto3.amazonaws.com/v1/documentation/api/latest/reference/services/iot.html#IoT.Client.update_certificate
* Java: https://docs.aws.amazon.com/AWSJavaSDK/latest/javadoc/com/amazonaws/services/iot/AWSIotClient.html#updateCertificate-com.amazonaws.services.iot.model.UpdateCertificateRequest-
* JS: https://docs.aws.amazon.com/AWSJavaScriptSDK/latest/AWS/Iot.html#updateCertificate-property
* And so on

You can see all of the Java control plane methods here: https://docs.aws.amazon.com/AWSJavaSDK/latest/javadoc/com/amazonaws/services/iot/AWSIot.html
