1.Configuration Settings
You can create any number of application settings required by your function code. There are also predefined application settings used by Functions. These settings are stored encrypted.
The Get-AzFunctionAppSetting cmdlet returns the existing application settings, as in the following example:
Get-AzFunctionAppSetting -Name <FUNCTION_APP_NAME> -ResourceGroupName <RESOURCE_GROUP_NAME>
The Update-AzFunctionAppSetting command adds or updates an application setting. The following example creates a setting with a key named CUSTOM_FUNCTION_APP_SETTING and a value of 12345 :
Update-AzFunctionAppSetting -Name <FUNCTION_APP_NAME> -ResourceGroupName <RESOURCE_GROUP_NAME> -AppSetting @{"CUSTOM_FUNCTION_APP_SETTING" = "12345"}
