No where I see documentation for implementation. I started form this post to get a valid token by implementing ServiceClientCredentials

after that I tired this code:

```c#
public async Task CreateAPIMroducts(myContract myData)
{
var serviceCredentials = new AzureApiManagementServiceCredentials(); //in this class I implement ServiceClientCredentials

        ApiManagementClient myClient = new ApiManagementClient(serviceCredentials);

        ProductContract productContract = new ProductContract("displayName");

        ProductContract result =await myClient .Product.CreateOrUpdateAsync(myData.ResourceGroupName, myData.ServiceName, myData.ProductId, productContract);
        return result;
    }

```

So I'm trying to create new Product into my APIM instance but I got this error: Microsoft.Rest.ValidationException: 'this.Client.SubscriptionId' cannot be null.

What I understand is to assign my subscription with the client I use but I don't know if I'm right or not and how to do it

Can you please challenge me with your ideas?

thank you! 😊

Thank you for your feedback. Tagging and routing to the team member best able to assist.

@TarekMansour , can you try adding myClient.SubscriptionId = "xxxx"; after client contruction? That should at least fix this error. Also I didn't see any assignment to productContract's properties.

[TarekMansour]

@allenjzhang Thank you! yes it works by adding myClient.SubscriptionId = "xxxx";

At the beginning I was testing the SDK that's why for productContract's properties I just initiate the displayName(required field)
now I'm calling that method from another service where I prepare the ProductContract.

More than adding myClient.SubscriptionId = "xxxx";, we need to override ProcessHttpRequestAsync to use the authentication token as an Authorization header:

``` c#
public override async Task ProcessHttpRequestAsync(HttpRequestMessage request, CancellationToken cancellationToken)
{
if (request == null) throw new ArgumentNullException("request");

        if (AuthenticationToken == null) throw new InvalidOperationException("Token Provider Cannot Be Null");

        request.Headers.Authorization = new AuthenticationHeaderValue("Bearer", AuthenticationToken);
        request.Headers.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));

        await base.ProcessHttpRequestAsync(request, cancellationToken);
    }

```

At the end I want to add a feedback to say even it works like we discussed the documentation still not clear as we are used to have in the official Microsoft documentation.
