Batch gets the update history of assets that overlap a time window. For IAM_POLICY content, this API outputs history when the asset and its attached IAM POLICY both exist. This can create gaps in the output history. Otherwise, this API outputs history with asset in both non-delete or deleted status. If a specified asset does not exist, this API returns an INVALID_ARGUMENT error.
HTTP request
GET https://cloudasset.googleapis.com/v1/{parent=*/*}:batchGetAssetsHistory
Required. The relative name of the root asset. It can only be an organization number (such as "organizations/123"), a project ID (such as "projects/my-project-id")", or a project number (such as "projects/12345").
Authorization requires one or more of the following IAM permissions on the specified resource parent:
Optional. The time window for the asset history. Both startTime and endTime are optional and if set, it must be after the current time minus 35 days. If endTime is not set, it is default to current timestamp. If startTime is not set, the snapshot of the assets at endTime will be returned. The returned results contain all temporal assets whose time window overlap with readTimeWindow.
relationshipTypes[]
string
Optional. A list of relationship types to output, for example: INSTANCE_TO_INSTANCEGROUP. This field should only be specified if contentType=RELATIONSHIP. * If specified: it outputs specified relationships' history on the [assetNames]. It returns an error if any of the [relationshipTypes] doesn't belong to the supported relationship types of the [assetNames] or if any of the [assetNames]'s types doesn't belong to the source types of the [relationshipTypes]. * Otherwise: it outputs the supported relationships' history on the [assetNames] or returns an error if any of the [assetNames]'s types has no relationship support. See Introduction to Cloud Asset Inventory for all supported asset types and relationship types.
