Deleting Object Tags

Functions

This API is used to delete the tags from an object. For more information about object tags, see Object Tags.

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: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.

Using SDKs to Call APIs

You are advised to use OBS SDKs to call APIs. SDKs encapsulate APIs to simplify development. You can call SDK API functions to access OBS without manually calculating signatures.
