DeleteAssetModel

Deletes an asset model. This action can't be undone. You must delete all assets created from an asset model before you can delete the model. Also, you can't delete an asset model if a parent asset model exists that contains a property formula expression that depends on the asset model that you want to delete. For more information, see Deleting assets and models in the AWS IoT SiteWise User Guide.

Request Syntax


DELETE /asset-models/assetModelId?clientToken=clientToken HTTP/1.1
If-Match: ifMatch
If-None-Match: ifNoneMatch
Match-For-Version-Type: matchForVersionType

URI Request Parameters

The request uses the following URI parameters.

assetModelId

The ID of the asset model to delete. This can be either the actual ID in UUID format, or else externalId: followed by the external ID, if it has one. For more information, see Referencing objects with external IDs in the AWS IoT SiteWise User Guide.

Length Constraints: Minimum length of 13. Maximum length of 139.

Pattern: ^[0-9a-f]{8}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{12}$|^externalId:[a-zA-Z0-9][a-zA-Z_\-0-9.:]*[a-zA-Z0-9]+

Required: Yes

clientToken

A unique case-sensitive identifier that you can provide to ensure the idempotency of the request. Don't reuse this client token if a new idempotent request is required.

Length Constraints: Minimum length of 36. Maximum length of 64.

Pattern: \S{36,64}

ifMatch

The expected current entity tag (ETag) for the asset model’s latest or active version (specified using matchForVersionType). The delete request is rejected if the tag does not match the latest or active version's current entity tag. See Optimistic locking for asset model writes in the AWS IoT SiteWise User Guide.

Pattern: ^[\w-]{43}$

ifNoneMatch

Accepts * to reject the delete request if an active version (specified using matchForVersionType as ACTIVE) already exists for the asset model.

Pattern: \*

matchForVersionType

Specifies the asset model version type (LATEST or ACTIVE) used in conjunction with If-Match or If-None-Match headers to determine the target ETag for the delete operation.

Valid Values: LATEST | ACTIVE
