2. Create an API
var apiData = new ApiCreateOrUpdateContent

4. Create a Subscription
var subscriptionData = new ApiManagementSubscriptionCreateOrUpdateContent

};
var subscriptionCollection = service.GetApiManagementSubscriptions();

// Get subscription keys
var keys = await subscription.GetSecretsAsync();

5. Set API Policy
var policyXml = @"

<value>CustomValue</value>
</set-header>
<base />
</inbound>
<backend>
<base />
</backend>
<outbound>
<base />
</outbound>
<on-error>
<base />
</on-error>
</policies>";
var policyData = new PolicyContractData
{
Value = policyXml,
Format = PolicyContentFormat.Xml
};
await api.GetApiPolicy().CreateOrUpdateAsync(
WaitUntil.Completed,
policyData);
