New-AzApiManagementBackendCredential to create ref to named value

[RobBowman]

I have a named value that contains a link to a key vault secret containing a function key.

I'd like to create an apim backend with an authorization credential with a "x-funcions-key" header that pulls it's value from the key vault secret via the named value.

In the portal, it would look like this:

I have tried the following code:

$nvName = "$env-365response-func-key-kv"
$nvFuncKey = Get-AzApiManagementNamedValue -Context $context -Name $nvName
$headers.add("x-functions-key", @($nvFuncKey.Name))
$credential = New-AzApiManagementBackendCredential -Header $headers 

This executes ok but rather than the resulting auth header value containing a reference to the named value, it simply contains a string of the name of the named value.

Anyone know how to fix this?

@RobBowman We sincerely apologies for the delay in getting back.

Please try this.

$context = New-AzApiManagementContext -ResourceGroupName "Issue19075" -ServiceName "Issue19075"

$nvFuncKey = Get-AzApiManagementNamedValue -Context $context -Name "issue19075nvfromkv"

$credential = New-AzApiManagementBackendCredential -Header @{"x-functions-key" = @("{{" + $nvFuncKey.Name + "}}")}

$backend = New-AzApiManagementBackend -Context $context -BackendId 123 -Url 'https://contoso.com/awesomeapi' -Protocol http -Title "first backend" -SkipCertificateChainValidation $true -Credential $credential -Description "my backend"
