Storage account Globally unique name Name of the new storage account used by your function app. Storage account names must be between 3 and 24 characters in length and may contain numbers and lowercase letters only. You can also use an existing account.
Click Create to provision and deploy the new function app.
Next, you create a function in the new function app.
Create a Queue triggered function
Expand your function app and click the + button next to Functions. If this is the first function in your function app, select Custom function. This displays the complete set of function templates.
Select the QueueTrigger template for your desired language, and use the settings as specified in the table.
Setting Suggested value Description Queue name myqueue-items Name of the queue to connect to in your Storage account.

Click Create to create your function.
Next, you connect to your Azure Storage account and create the myqueue-items storage queue.
Create the queue
In your function, click Integrate, expand Documentation, and copy both Account name and Account key. You use these credentials to connect to the storage account. If you have already connected your storage account, skip to step 4.
Run the Microsoft Azure Storage Explorer tool, click the connect icon on the left, choose Use a storage account name and key, and click Next.
Enter the Account name and Account key from step 1, click Next and then Connect.
Expand the attached storage account, right-click Queues, click Create queue, type

Wait for a few seconds, then go back to your function logs and verify that the new message has been read from the queue.
Back in Storage Explorer, click Refresh and verify that the message has been processed and is no longer in the queue.

If you do not plan to continue, click the Resource group for the function app in the portal, and then click Delete.
You have created a function that runs when a message is added to a storage queue.
