Deleting Object Tags

Functions

This operation deletes tags from an object.

If you do not specify a version ID in a request, make sure that you have the DeleteObjectTagging permission. If you do specify a version ID in a request, make sure that you have the DeleteObjectTagging and DeleteObjectVersionTagging permissions. By default, only the object owner can perform this operation. The object owner can grant this permission to others by using a bucket or user policy.

OBS deletes tags from the current object version by default. You can use the versionId parameter to delete tags from any other version. If the version you are deleting tags from is a delete marker, OBS returns 404 Not Found.

Authorization Information

To call this API, you must be the object owner or have the permissions to delete object tags. You are advised to use IAM or bucket policies for authorization. For details about OBS authorization methods, see Differences Between OBS Permissions Control Methods.

• If you use IAM for authorization, you need to use either role/policy-based authorization or identity policy-based authorization and configure the required permissions:
  • If you use role/policy-based authorization (IAM v3 APIs in the old IAM version), you need to grant the obs:object:DeleteObjectTagging (versioning disabled) and obs:object:DeleteObjectVersionTagging (versioning enabled or suspended) permissions. For details, see Creating a Custom IAM Policy.
  • If you use identity policy-based authorization (IAM v5 APIs in the new IAM version), you need to grant the obs:object:deleteObjectTagging (versioning disabled) and obs:object:deleteObjectVersionTagging (versioning enabled or suspended) permissions, as shown in the following table. For details, see Creating a Custom IAM Identity Policy.

    Action	Access Level	Resource Type (*: Required)	Condition Key	Alias	Dependencies
    obs:object:deleteObjectTagging (versioning disabled) obs:object:deleteObjectVersionTagging (versioning enabled or suspended)	Tagging	object *	g:EnterpriseProjectId g:ResourceTag/<tag-key>	-	-
    		-	obs:EpochTime obs:SourceIp obs:TlsVersion obs:CustomDomain

• If you use bucket policies for authorization, you need to grant the obs:object:DeleteObjectTagging (versioning disabled) and obs:object:DeleteObjectVersionTagging (versioning enabled or suspended) permissions. For details, see Creating a Custom Bucket Policy.
