Core Workflows

1. Create API Center Service

csharp
using Azure.ResourceManager.ApiCenter;
using Azure.ResourceManager.ApiCenter.Models;

ResourceGroupResource resourceGroup = await client
    .GetDefaultSubscriptionAsync()
    .Result
    .GetResourceGroupAsync("my-resource-group");

ApiCenterServiceCollection services = resourceGroup.GetApiCenterServices();

ApiCenterServiceData data = new ApiCenterServiceData(AzureLocation.EastUS)
{
    Identity = new ManagedServiceIdentity(ManagedServiceIdentityType.SystemAssigned)
};

ArmOperation<ApiCenterServiceResource> operation = await services
    .CreateOrUpdateAsync(WaitUntil.Completed, "my-api-center", data);

ApiCenterServiceResource service = operation.Value;

2. Create Workspace

csharp
ApiCenterWorkspaceCollection workspaces = service.GetApiCenterWorkspaces();

ApiCenterWorkspaceData workspaceData = new ApiCenterWorkspaceData
{
    Title = "Engineering APIs",
    Description = "APIs owned by the engineering team"
};

ArmOperation<ApiCenterWorkspaceResource> operation = await workspaces
    .CreateOrUpdateAsync(WaitUntil.Completed, "engineering", workspaceData);

ApiCenterWorkspaceResource workspace = operation.Value;

3. Create API

csharp
ApiCenterApiCollection apis = workspace.GetApiCenterApis();

ApiCenterApiData apiData = new ApiCenterApiData
{
    Title = "Orders API",
    Description = "API for managing customer orders",
    Kind = ApiKind.Rest,
    LifecycleStage = ApiLifecycleStage.Production,
    TermsOfService = new ApiTermsOfService
    {
        Uri = new Uri("https://example.com/terms")
    },
    ExternalDocumentation = 
    {
        new ApiExternalDocumentation
        {
            Title = "Documentation",
            Uri = new Uri("https://docs.example.com/orders")
        }
    },
    Contacts =
    {
        new ApiContact
        {
            Name = "API Support",
            Email = "api-support@example.com"
        }
    }
};

// Add custom metadata
apiData.CustomProperties = BinaryData.FromObjectAsJson(new
{
    team = "orders-team",
    costCenter = "CC-1234"
});

ArmOperation<ApiCenterApiResource> operation = await apis
    .CreateOrUpdateAsync(WaitUntil.Completed, "orders-api", apiData);

ApiCenterApiResource api = operation.Value;

4. Create API Version

csharp
ApiCenterApiVersionCollection versions = api.GetApiCenterApiVersions();

ApiCenterApiVersionData versionData = new ApiCenterApiVersionData
{
    Title = "v1.0.0",
    LifecycleStage = ApiLifecycleStage.Production
};

ArmOperation<ApiCenterApiVersionResource> operation = await versions
    .CreateOrUpdateAsync(WaitUntil.Completed, "v1-0-0", versionData);

ApiCenterApiVersionResource version = operation.Value;

5. Create API Definition (Upload OpenAPI Spec)

csharp
ApiCenterApiDefinitionCollection definitions = version.GetApiCenterApiDefinitions();

ApiCenterApiDefinitionData definitionData = new ApiCenterApiDefinitionData
{
    Title = "OpenAPI Specification",
    Description = "Orders API OpenAPI 3.0 definition"
};

ArmOperation<ApiCenterApiDefinitionResource> operation = await definitions
    .CreateOrUpdateAsync(WaitUntil.Completed, "openapi", definitionData);

ApiCenterApiDefinitionResource definition = operation.Value;

// Import specification
string openApiSpec = await File.ReadAllTextAsync("orders-api.yaml");

ApiSpecImportContent importContent = new ApiSpecImportContent
{
    Format = ApiSpecImportSourceFormat.Inline,
    Value = openApiSpec,
    Specification = new ApiSpecImportSpecification
    {
        Name = "openapi",
        Version = "3.0.1"
    }
};

await definition.ImportSpecificationAsync(WaitUntil.Completed, importContent);

6. Export API Specification

csharp
ApiCenterApiDefinitionResource definition = await client
    .GetApiCenterApiDefinitionResource(definitionResourceId)
    .GetAsync();

ArmOperation<ApiSpecExportResult> operation = await definition
    .ExportSpecificationAsync(WaitUntil.Completed);

ApiSpecExportResult result = operation.Value;

// result.Format - e.g., "inline"
// result.Value - the specification content

7. Create Environment

csharp
ApiCenterEnvironmentCollection environments = workspace.GetApiCenterEnvironments();

ApiCenterEnvironmentData envData = new ApiCenterEnvironmentData
{
    Title = "Production",
    Description = "Production environment",
    Kind = ApiCenterEnvironmentKind.Production,
    Server = new ApiCenterEnvironmentServer
    {
        ManagementPortalUris = { new Uri("https://portal.azure.com") }
    },
    Onboarding = new EnvironmentOnboardingModel
    {
        Instructions = "Contact platform team for access",
        DeveloperPortalUris = { new Uri("https://developer.example.com") }
    }
};

ArmOperation<ApiCenterEnvironmentResource> operation = await environments
    .CreateOrUpdateAsync(WaitUntil.Completed, "production", envData);

8. Create Deployment

csharp
ApiCenterDeploymentCollection deployments = workspace.GetApiCenterDeployments();

// Get environment resource ID
ResourceIdentifier envResourceId = ApiCenterEnvironmentResource.CreateResourceIdentifier(
    subscriptionId, resourceGroupName, serviceName, workspaceName, "production");

// Get API definition resource ID
ResourceIdentifier definitionResourceId = ApiCenterApiDefinitionResource.CreateResourceIdentifier(
    subscriptionId, resourceGroupName, serviceName, workspaceName, 
    "orders-api", "v1-0-0", "openapi");

ApiCenterDeploymentData deploymentData = new ApiCenterDeploymentData
{
    Title = "Orders API - Production",
    Description = "Production deployment of Orders API v1.0.0",
    EnvironmentId = envResourceId,
    DefinitionId = definitionResourceId,
    State = ApiCenterDeploymentState.Active,
    Server = new ApiCenterDeploymentServer
    {
        RuntimeUris = { new Uri("https://api.example.com/orders") }
    }
};

ArmOperation<ApiCenterDeploymentResource> operation = await deployments
    .CreateOrUpdateAsync(WaitUntil.Completed, "orders-api-prod", deploymentData);

9. Create Metadata Schema

csharp
ApiCenterMetadataSchemaCollection schemas = service.GetApiCenterMetadataSchemas();

string jsonSchema = """
{
    "type": "object",
    "properties": {
        "team": {
            "type": "string",
            "title": "Owning Team"
        },
        "costCenter": {
            "type": "string",
            "title": "Cost Center"
        },
        "dataClassification": {
            "type": "string",
            "enum": ["public", "internal", "confidential"],
            "title": "Data Classification"
        }
    },
    "required": ["team"]
}
""";

ApiCenterMetadataSchemaData schemaData = new ApiCenterMetadataSchemaData
{
    Schema = jsonSchema,
    AssignedTo =
    {
        new MetadataAssignment
        {
            Entity = MetadataAssignmentEntity.Api,
            Required = true
        }
    }
};

ArmOperation<ApiCenterMetadataSchemaResource> operation = await schemas
    .CreateOrUpdateAsync(WaitUntil.Completed, "api-metadata", schemaData);

10. List and Search APIs

csharp
// List all APIs in a workspace
ApiCenterWorkspaceResource workspace = await client
    .GetApiCenterWorkspaceResource(workspaceResourceId)
    .GetAsync();

await foreach (ApiCenterApiResource api in workspace.GetApiCenterApis())
{
    Console.WriteLine($"API: {api.Data.Title}");
    Console.WriteLine($"  Kind: {api.Data.Kind}");
    Console.WriteLine($"  Stage: {api.Data.LifecycleStage}");
    
    // List versions
    await foreach (ApiCenterApiVersionResource version in api.GetApiCenterApiVersions())
    {
        Console.WriteLine($"  Version: {version.Data.Title}");
    }
}

// List environments
await foreach (ApiCenterEnvironmentResource env in workspace.GetApiCenterEnvironments())
{
    Console.WriteLine($"Environment: {env.Data.Title} ({env.Data.Kind})");
}

// List deployments
await foreach (ApiCenterDeploymentResource deployment in workspace.GetApiCenterDeployments())
{
    Console.WriteLine($"Deployment: {deployment.Data.Title}");
    Console.WriteLine($"  State: {deployment.Data.State}");
}

Key Types Reference

Type Purpose
ApiCenterServiceResource API Center service instance
ApiCenterWorkspaceResource Logical grouping of APIs
ApiCenterApiResource Individual API
ApiCenterApiVersionResource Version of an API
ApiCenterApiDefinitionResource API specification (OpenAPI, etc.)
ApiCenterEnvironmentResource Deployment environment
ApiCenterDeploymentResource API deployment to environment
ApiCenterMetadataSchemaResource Custom metadata schema

Best Practices

  1. Organize with workspaces — Group APIs by team, domain, or product
  2. Use metadata schemas — Define custom properties for governance
  3. Track lifecycle stages — Keep API status current (design → production → deprecated)
  4. Document environments — Include onboarding instructions and portal URIs
  5. Version consistently — Use semantic versioning for API versions
  6. Import specifications — Upload OpenAPI/GraphQL specs for discovery
  7. Link deployments — Connect APIs to their runtime environments
  8. Use managed identity — Enable SystemAssigned identity for secure integrations

Error Handling

csharp
using Azure;

try
{
    ArmOperation<ApiCenterApiResource> operation = await apis
        .CreateOrUpdateAsync(WaitUntil.Completed, "my-api", apiData);
}
catch (RequestFailedException ex) when (ex.Status == 409)
{
    Console.WriteLine("API already exists with conflicting configuration");
}
catch (RequestFailedException ex) when (ex.Status == 400)
{
    Console.WriteLine($"Invalid request: {ex.Message}");
}
catch (RequestFailedException ex)
{
    Console.WriteLine($"Azure error: {ex.Status} - {ex.Message}");
}
