API Management soft-delete

APPLIES TO: All API Management tiers

With API Management soft-delete, you can recover and restore a recently deleted API Management instance. This feature protects against accidental deletion of your API Management instance.

Currently, depending on how you delete an API Management instance, the instance is either soft-deleted and recoverable during a retention period, or permanently deleted:

• When you use the Azure portal or REST API version 2020-06-01-preview or later to delete an API Management instance, it's soft-deleted.
• An API Management instance deleted using a REST API version before 2020-06-01-preview is permanently deleted.
• An API Management instance deleted using API Management commands in Azure PowerShell or Azure CLI is soft-deleted.

Supporting interfaces

Recovery and other operations on a soft-deleted instance are enabled through REST API version 2020-06-01-preview or later, or the Azure SDK for .NET, Go, or Python.

Soft-delete behavior

You can use any API version to create your API Management instance. When you use the Azure portal, Azure REST API, or another Azure tool using API version 2020-06-01-preview or later to delete an API Management instance, the instance is automatically soft-deleted.

Once an API Management instance is soft-deleted, the service exists in a deleted state, making it inaccessible to normal API Management operations.

In the soft-deleted state:

• The API Management instance can only be listed, recovered, or purged (permanently deleted).
• Azure will schedule the permanent deletion of the underlying data corresponding to the API Management instance after the predetermined (48 hour) retention period.
• You can't reuse the name of the API Management instance.

If you don't recover or purge your API Management instance within 48 hours, the instance is automatically deleted permanently.

List deleted API Management instances

You can verify that a soft-deleted API Management instance is available to restore (undelete), by using either the Deleted Services Get By Name operations or the List By Subscription operation.

Get a soft-deleted instance by name

Use the API Management Get By Name operation, substituting {subscriptionId}, {location}, and {serviceName} with your Azure subscription, resource location name, and API Management instance name:

GET https://management.chinacloudapi.cn/subscriptions/{subscriptionId}/providers/Microsoft.ApiManagement/locations/{location}/deletedservices/{serviceName}?api-version=2021-08-01

If it's available for undelete, Azure returns a record of the API Management instance showing its deletionDate and scheduledPurgeDate, for example:

{
    "id": "subscriptions/########-####-####-####-############/providers/Microsoft.ApiManagement/locations/chinanorth/deletedservices/apimtest",
    "name": "apimtest",
    "type": "Microsoft.ApiManagement/deletedservices",
    "location": "China North",
    "properties": {
        "serviceId": "/subscriptions/########-####-####-####-############/resourceGroups/apimtestgroup/providers/Microsoft.ApiManagement/service/apimtest",
        "scheduledPurgeDate": "2021-11-26T19:40:26.3596893Z",
        "deletionDate": "2021-11-24T19:40:50.1013572Z"
    }
}

List all soft-deleted instances for a given subscription

Use the API Management List By Subscription operation, substituting {subscriptionId} with your subscription ID:

GET https://management.chinacloudapi.cn/subscriptions/{subscriptionId}/providers/Microsoft.ApiManagement/deletedservices?api-version=2021-08-01

This command returns a list all soft-deleted services available for undelete under the given subscription, showing the deletionDate and scheduledPurgeDate for each.

Recover a soft deleted instance

Use the API Management Create Or Update operation, substituting {subscriptionId}, {resourceGroup}, and {apimServiceName} with your Azure subscription, resource group name, and API Management name:

PUT
https://management.chinacloudapi.cn/subscriptions/{subscriptionId}/resourceGroups/{resourceGroup}/providers/Microsoft.ApiManagement/service/{apimServiceName}?api-version=2021-08-01

. . . and set the restore property to true in the request body. (When this flag is specified and set to true, all other properties are ignored.) For example:

{
  "properties": {
    "publisherEmail": "help@contoso.com",
    "publisherName": "Contoso",
    "restore": true
  },
  "sku": {
    "name": "Developer",
    "capacity": 1
  },
  "location": "China North"
}

Purge a soft-deleted instance

Use the API Management Purge operation, substituting {subscriptionId}, {location}, and {serviceName} with your Azure subscription, resource location, and API Management name.

DELETE https://management.chinacloudapi.cn/subscriptions/{subscriptionId}/providers/Microsoft.ApiManagement/locations/{location}/deletedservices/{serviceName}?api-version=2021-08-01

This command permanently deletes your API Management instance from Azure.

Reuse an API Management instance name after deletion

You can reuse the name of an API Management instance in a new deployment:

• After the instance is permanently deleted (purged) from Azure.

• In the same subscription as the original instance.

You can't reuse the name of an API Management instance in a new deployment:

• While the instance is soft-deleted.

• In a subscription other than the one used to deploy the original instance, even after the original instance is permanently deleted (purged) from Azure. This restriction applies whether the new subscription used is in the same or a different Microsoft Entra tenant. The restriction is in effect for several days or longer after deletion, depending on the subscription type.

  This restriction is because Azure reserves the service host name to a customer's tenant for a reservation period to prevent the threat of subdomain takeover with dangling domain name system (DNS) entries. For more information, see Prevent dangling DNS entries and avoid subdomain takeover. To see all dangling DNS entries for subscriptions in a Microsoft Entra tenant, see Identify dangling DNS entries.
