How to download Azure Function (Python) .zip file?

Question

The docs here (from 2018) say to click Download app content from the Portal to retrieve a .zip file of your Azure Function.

However, this option is grayed out for my Python function:

The doc goes on to provide an alternative method for retrieving a .zip file using REST API with the following url https://<function_app>.scm.azurewebsites.net/api/zip/site/wwwroot/.

Unfortunately, this downloads a download.zip file containing only the hosts.json file rather than the Function code and associated files.

So, how do I download my Python Function as a .zip file from either Azure Portal, REST API or the scm backend?

EDIT 1: Trying the two proposed solutions so far yield no results either.

• AzureWebJobsStorage: No scm-deployments container available.

• FTPS option: No .zip file available. Only the host.json file.

Finally! Figured this out.

To download the .zip file of a deployed Python Azure Function:

• Go to https://<function-app-name>.scm.azurewebsites.net/api/vfs/data/SitePackages/
• The body will look something like:

• Go to the href URL shown with the latest mtime to download the file
• Notice: The latest timestamp is lower in the list (at least for me)

Its documented here

Answer 2

If you have access to the Function's storage account then just download from scm-releases container.

You can find the account connection string in AzureWebJobsStorage parameter under Configuration in portal (App Settings).
