``json
{
"serviceBusNamespace": "spsbusns1128",
"serviceBusKey": "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX",
"serviceBusPolicyName": "SendPolicy",
"topicName": "test", // or use "queueName",
"ExpireTimeInSeconds": 3600 // optional
}
`

Note: The ExpireTimeInSeconds environment variable is optional. If not provided, it defaults to 3600 seconds, which represents 1 hour.
