Invoking Service Bus function via admin endpoint and passing payload + headers

[SeanFeldman]

The documentation shows how to invoke HTTP-triggered functions. It shows Azure Storage Queues for non-HTTP functions, but that scenario is straightforward because the data posted is transformed into the Storage Queue payload as-is. With ASB, custom headers (application properties) can also be passed in addition to the message payload. Is it possible to achieve passing headers + body for the message? And if 'yes', what's the correct syntax?

Original question from StackOverflow.

Use ServiceBusSender and construct the message to be sent as below (just an example):

        var ret = new ServiceBusMessage(bodyData)
        {
            ContentType = ...,
            Subject = ...,
        };
        ret.ApplicationProperties["YourProperty"] = value;

Note the use of ApplicationProperties dictionary for custom "headers". Also note that only some data types are supported for the value.

@zvrba, did you read the referenced documentation?

You can also run a non-HTTP function locally using REST by calling a special endpoint called an administrator endpoint. Use this format to call the admin endpoint and trigger a specific non-HTTP function

What you're showing is not an admin endpoint invocation, which is what this question is about.
