    service_name="my-apim",
    product_id="premium",
    parameters=ProductContract(
        display_name="Premium",
        description="Premium tier with unlimited access",
        subscription_required=True,
        approval_required=False,
        state="published"
    )
)

print(f"Created product: {product.display_name}")

Add API to Product

client.product_api.create_or_update(

    product_id="premium",
    api_id="my-api"
)

subscription = client.subscription.create_or_update(
    resource_group_name="my-resource-group",
    service_name="my-apim",
    sid="my-subscription",
    parameters=SubscriptionCreateParameters(
        display_name="My Subscription",
        scope=f"/products/premium",
        state="active"
    )
)

print(f"Subscription key: {subscription.primary_key}")

Set API Policy

from azure.mgmt.apimanagement.models import PolicyContract

policy_xml = """
<policies>
    <inbound>
        <rate-limit calls="100" renewal-period="60" />
        <set-header name="X-Custom-Header" exists-action="override">
            <value>CustomValue</value>
        </set-header>
    </inbound>
    <backend>
        <forward-request />
    </backend>
    <outbound />
    <on-error />
</policies>
"""

client.api_policy.create_or_update(
    resource_group_name="my-resource-group",
    service_name="my-apim",
    api_id="my-api",
    policy_id="policy",
    parameters=PolicyContract(
        value=policy_xml,
        format="xml"
    )
)

Create Named Value (Secret)

from azure.mgmt.apimanagement.models import NamedValueCreateContract

named_value = client.named_value.begin_create_or_update(
    resource_group_name="my-resource-group",
    service_name="my-apim",
    named_value_id="backend-api-key",
    parameters=NamedValueCreateContract(
        display_name="Backend API Key",
        value="secret-key-value",
        secret=True
    )
).result()

Create Backend

from azure.mgmt.apimanagement.models import BackendContract

backend = client.backend.create_or_update(
    resource_group_name="my-resource-group",
    service_name="my-apim",
    backend_id="my-backend",
    parameters=BackendContract(
        url="https://api.backend.example.com",
        protocol="http",
        description="My backend service"
    )
)

Create User

from azure.mgmt.apimanagement.models import UserCreateParameters

user = client.user.create_or_update(
    resource_group_name="my-resource-group",
    service_name="my-apim",
    user_id="newuser",
    parameters=UserCreateParameters(
        email="[email protected]",
        first_name="John",
        last_name="Doe"
    )
)

Operation Groups

| Group | Purpose | |-------|---------| | api_management_service | APIM instance management | | api | API operations | | api_operation | API operation details | | api_policy | API-level policies | | product | Product management | | product_api | Product-API associations | | subscription | Subscription management | | user | User management | | named_value | Named values/secrets | | backend | Backend services | | certificate | Certificates | | gateway | Self-hosted gateways |

Best Practices

1. Use named values for secrets and configuration
2. Apply policies at appropriate scopes (global, product, API, operation)
3. Use products to bundle APIs and manage access
4. Enable Application Insights for monitoring
5. Use backends to abstract backend services
6. Version your APIs using APIM's versioning features
