Deleting a Bucket Policy

Functions

This operation uses the policy sub-resources to delete the policy of a specified bucket.

To perform this operation, the user must be the bucket owner or the bucket owner's IAM user that has permissions required for deleting bucket policies.

The 204 error code "No Content" is returned regardless of whether a requested bucket policy exists or not.

Authorization Information

To call this API, you must be the bucket owner or have the permission to delete bucket policies. 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:bucket:DeleteBucketPolicy 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 need to grant the obs:bucket:deleteBucketPolicy permission, as shown in the following table. For details, see Creating a Custom IAM Identity Policy.
