Core Workflow

\n

1. Create API Management Service

\n
using Azure.ResourceManager.ApiManagement;\nusing Azure.ResourceManager.ApiManagement.Models;\n\n// Get resource group\nvar resourceGroup = await subscription\n    .GetResourceGroupAsync(\"my-resource-group\");\n\n// Define service\nvar serviceData = new ApiManagementServiceData(\n    location: AzureLocation.EastUS,\n    sku: new ApiManagementServiceSkuProperties(\n        ApiManagementServiceSkuType.Developer, \n        capacity: 1),\n    publisherEmail: \"admin@contoso.com\",\n    publisherName: \"Contoso\");\n\n// Create service (long-running operation - can take 30+ minutes)\nvar serviceCollection = resourceGroup.Value.GetApiManagementServices();\nvar operation = await serviceCollection.CreateOrUpdateAsync(\n    WaitUntil.Completed,\n    \"my-apim-service\",\n    serviceData);\n\nApiManagementServiceResource service = operation.Value;\n
\n

2. Create an API

\n
var apiData = new ApiCreateOrUpdateContent\n{\n    DisplayName = \"My API\",\n    Path = \"myapi\",\n    Protocols = { ApiOperationInvokableProtocol.Https },\n    ServiceUri = new Uri(\"https://backend.contoso.com/api\")\n};\n\nvar apiCollection = service.GetApis();\nvar apiOperation = await apiCollection.CreateOrUpdateAsync(\n    WaitUntil.Completed,\n    \"my-api\",\n    apiData);\n\nApiResource api = apiOperation.Value;\n
\n

3. Create a Product

\n
var productData = new ApiManagementProductData\n{\n    DisplayName = \"Starter\",\n    Description = \"Starter tier with limited access\",\n    IsSubscriptionRequired = true,\n    IsApprovalRequired = false,\n    SubscriptionsLimit = 1,\n    State = ApiManagementProductState.Published\n};\n\nvar productCollection = service.GetApiManagementProducts();\nvar productOperation = await productCollection.CreateOrUpdateAsync(\n    WaitUntil.Completed,\n    \"starter\",\n    productData);\n\nApiManagementProductResource product = productOperation.Value;\n\n// Add API to product\nawait product.GetProductApis().CreateOrUpdateAsync(\n    WaitUntil.Completed,\n    \"my-api\");\n
\n

4. Create a Subscription

\n
var subscriptionData = new ApiManagementSubscriptionCreateOrUpdateContent\n{\n    DisplayName = \"My Subscription\",\n    Scope = $\"/products/{product.Data.Name}\",\n    State = ApiManagementSubscriptionState.Active\n};\n\nvar subscriptionCollection = service.GetApiManagementSubscriptions();\nvar subOperation = await subscriptionCollection.CreateOrUpdateAsync(\n    WaitUntil.Completed,\n    \"my-subscription\",\n    subscriptionData);\n\nApiManagementSubscriptionResource subscription = subOperation.Value;\n\n// Get subscription keys\nvar keys = await subscription.GetSecretsAsync();\nConsole.WriteLine($\"Primary Key: {keys.Value.PrimaryKey}\");\n
\n

5. Set API Policy

\n
var policyXml = @\"\n<policies>\n    <inbound>\n        <rate-limit calls=\"\"100\"\" renewal-period=\"\"60\"\" />\n        <set-header name=\"\"X-Custom-Header\"\" exists-action=\"\"override\"\">\n            <value>CustomValue</value>\n        </set-header>\n        <base />\n    </inbound>\n    <backend>\n        <base />\n    </backend>\n    <outbound>\n        <base />\n    </outbound>\n    <on-error>\n        <base />\n    </on-error>\n</policies>\";\n\nvar policyData = new PolicyContractData\n{\n    Value = policyXml,\n    Format = PolicyContentFormat.Xml\n};\n\nawait api.GetApiPolicy().CreateOrUpdateAsync(\n    WaitUntil.Completed,\n    policyData);\n
\n

6. Backup and Restore

\n
// Backup\nvar backupParams = new ApiManagementServiceBackupRestoreContent(\n    storageAccount: \"mystorageaccount\",\n    containerName: \"apim-backups\",\n    backupName: \"backup-2024-01-15\")\n{\n    AccessType = StorageAccountAccessType.SystemAssignedManagedIdentity\n};\n\nawait service.BackupAsync(WaitUntil.Completed, backupParams);\n\n// Restore\nawait service.RestoreAsync(WaitUntil.Completed, backupParams);\n
\n

Best Practices

\n
    \n
  1. Use WaitUntil.Completed for operations that must finish before proceeding
    2. \n
  2. Use WaitUntil.Started for long operations like service creation (30+ min)
    3. \n
  3. Always use DefaultAzureCredential — never hardcode keys
    4. \n
  4. Handle RequestFailedException for ARM API errors
    5. \n
  5. Use CreateOrUpdateAsync for idempotent operations
    6. \n
  6. Navigate hierarchy via Get* methods (e.g., service.GetApis())
    7. \n
  7. Policy format — Use XML format for policies; JSON is also supported
    8. \n
  8. Service creation — Developer SKU is fastest for testing (~15-30 min)
    9. \n
\n

Error Handling

\n
using Azure;\n\ntry\n{\n    var operation = await serviceCollection.CreateOrUpdateAsync(\n        WaitUntil.Completed, serviceName, serviceData);\n}\ncatch (RequestFailedException ex) when (ex.Status == 409)\n{\n    Console.WriteLine(\"Service already exists\");\n}\ncatch (RequestFailedException ex) when (ex.Status == 400)\n{\n    Console.WriteLine($\"Bad request: {ex.Message}\");\n}\ncatch (RequestFailedException ex)\n{\n    Console.WriteLine($\"ARM Error: {ex.Status} - {ex.ErrorCode}: {ex.Message}\");\n}\n
