Aborting a Multipart Upload

Function

You can call this API to abort a multipart upload. For details about the multipart upload, see Multipart Upload. You cannot upload or list parts after operations to merge parts or abort a multipart upload are performed.

Authorization

To call this API, you must be the bucket owner or have the permission to abort multipart uploads. 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 must have the obs:object:AbortMultipartUpload permission. For details, see Creating a Custom IAM Policy.
  • If you use identity policy-based authorization (IAM v5 APIs in the new IAM version), you must have the obs:object:abortMultipartUpload permission, as shown in the following table. For details, see Creating a Custom IAM Identity Policy.

• If you use bucket policies for authorization, you must have the obs:object:AbortMultipartUpload permission. For details, see Creating a Custom Bucket Policy.
