    Hey Parvin! I'm not quite sure what you mean by sending a message using certificate authentication. Are you referring to connecting to a Solace broker using certificate authentication? Or are you referring to sending messages to a queue? And what API are you using to connect to the broker?

    Options to connect to the broker using Python

    1. MQTT: you can use paho mqtt to connect to the broker. For certificate connection, all you need to do it client.tls_set(ca_certs="path_to_.pem_cert")
    2. Solace API: you will need to add this configuration property in your broker config prior connecting to the broker "solace.messaging.tls.trust-store-path": "path_to_.pem_cert"

    Sending messages

    Regardless the option you choose to connect to the broker, you can a JSON formatted body in the message. If you are sending messages on a topic, you can configure your queue on the broker to subscribe to a topic and it will receive the messages with the json body payload you sent from your application

    @Pravin if you mean you would like to use client certificate authentication for your connection (as opposed to basic auth), the Python API supports that. I don't have any code at the moment, but it's mainly just a set of properties in the config. The API docs show this here: https://docs.solace.com/API-Developer-Online-Ref-Documentation/python/source/rst/solace.messaging.config.solace_properties.html#module-solace.messaging.config.solace_properties.authentication_properties
    Do you have your client certs set up and loaded on the broker?

    Here is the documentation on how this needs to be set up on the broker.
