As we've just seen, trigger binding also defines the first input parameter for your function. On top of that, you can add other bindings to specify additional input parameters. As you will see in the table later in this chapter, certain types of bindings can serve as input, but not as triggers.

As an example, we will use an input-only binding used for Azure Storage Queue, as shown in the following code:
