Queue name c. %input_queue%: In Azure Functions, you can use the %name% syntax in the function.json file to reference app settings. So, to reference the queue name set by an app setting named input_queue, you would use %input_queue%.

Blob name a. {queueTrigger}: The {queueTrigger} binding expression gets the content of the queue message that triggered the function. This can be used to create a blob with the same name as the content of the message.
