List Operations
const url = 'https://example.com/topology/v1/operations';const options = {method: 'GET'};
try { const response = await fetch(url, options); const data = await response.json(); console.log(data);} catch (error) { console.error(error);}curl --request GET \ --url https://example.com/topology/v1/operationsReturns a paginated list of operations, optionally filtered by resource.
Parameters
Section titled “ Parameters ”Query Parameters
Section titled “Query Parameters ”Page Size
Maximum number of operations to return. The service may return fewer than this value. If unspecified, at most 20 operations will be returned. The maximum value is 100; values above 100 will be coerced to 100.
Page Token
A page token, received from a previous ListOperations call.
Provide this to retrieve the subsequent page. When paginating,
all other parameters provided to ListOperations must match the call
that provided the page token.
Filter
AIP-160 filter expression (e.g., “resource_type=Region”).
Order By
AIP-132 ordering expression.
Responses
Section titled “ Responses ”OK
ListTopologyOperationsResponse
Response message for ListOperations.
Note: This API intentionally omits total_size from list responses.
Keyset pagination does not support efficient total count computation
(COUNT(*) requires a full table scan). Per AIP-158, total_size is optional.
object
Operations
The list of operations.
Topology Operation
An acknowledgment of a mutation request, carrying tracking metadata, errors, and warnings. Follows GCP’s Operations pattern (AIP-151).
object
Operation ID
Unique identifier for this operation.
Resource ID
The ID of the resource affected by this operation. May be empty for async operations where the resource does not yet exist.
Resource Type
The type of resource (e.g., “Region”, “Zone”, “ResourcePool”, “DeploymentTarget”).
Operation Type
The kind of mutation that was requested.
Status
Current lifecycle state of the operation.
Insert Time
When the operation was first created.
Start Time
When the operation started executing.
End Time
When the operation completed (either successfully or with errors).
Errors
Business rule errors encountered during the operation.
Operation Error
A structured error returned inside an operation when a business rule fails.
object
Error Code
Numeric identifier following the S_SSS_EEE convention.
Description
Human-readable explanation of the error.
Warnings
Non-fatal notices about the operation.
Operation Warning
A non-fatal notice attached to an operation.
object
Warning Code
Numeric identifier following the S_SSS_EEE convention.
Description
Human-readable explanation of the warning.
Progress
Percentage of completion (0-100).
Next Page Token
A token, which can be sent as page_token to retrieve the next page.
If this field is empty, there are no subsequent pages.
Example
{ "operations": [ { "operation_type": "TOPOLOGY_OPERATION_PROTO_TYPE_UNSPECIFIED", "status": "TOPOLOGY_OPERATION_STATUS_UNSPECIFIED" } ]}default
Section titled “default ”Default error response
The Status type defines a logical error model that is suitable for different programming environments, including REST APIs and RPC APIs. It is used by gRPC. Each Status message contains three pieces of data: error code, error message, and error details. You can find out more about this error model and how to work with it in the API Design Guide.
object
The status code, which should be an enum value of [google.rpc.Code][google.rpc.Code].
A developer-facing error message, which should be in English. Any user-facing error message should be localized and sent in the [google.rpc.Status.details][google.rpc.Status.details] field, or localized by the client.
A list of messages that carry the error details. There is a common set of message types for APIs to use.
Contains an arbitrary serialized message along with a @type that describes the type of the serialized message.
object
The type of the serialized message.
