How to Subscribe to AWS IoT Core Topics using Access token

[jbyang1]

Hello
I'm going to subscribe to topics that are being published in AWS IoT Core.

I successfully subscribed using mqtt5_sub.py and my certificate file, but I would like to know how to subscribe Topic using Aces token.
mqtt5_sub.py [https://github.com/aws/aws-iot-device-sdk-python-v2/blob/main/samples/mqtt5_pubsub.py]

What's an access token?

Oh, I'm sorry. I was mistaken,
This is the access key.

There isn't a websockets-specific mqtt5 sample, but the process would be almost the same as mtls with cert-key except rather than the mtls builder constructor, you'd use the websockets-sigv4 constructor here: https://github.com/aws/aws-iot-device-sdk-python-v2/blob/main/awsiot/mqtt5_client_builder.py#L504

Thank you.
I'm looking at the same thing, and thank you again for your help

The 311 websocket sample shows credentials provider creation. In general, the default provider is a good place to start unless you have specialized needs (x509 or cognito): https://github.com/aws/aws-iot-device-sdk-python-v2/blob/main/samples/websocket_connect.py#L34
