    DELETE Multiple Objects

    Last updated: 2021-08-30 14:18:13

      Overview

      This API is used to delete multiple objects (up to 1,000) from a bucket in a single request. COS provides the following two response modes:

      • Quiet: returns only information about objects that failed to delete and the error messages.
      • Verbose: returns the deletion results of each object.

      To call this API, you need to have permission to write to the bucket.

      API Explorer is recommended.
      Debug
      API Explorer makes it easy to make online API calls, verify signatures, generate SDK code, search for APIs, etc. You can also use it to query the content of each request as well as its response.

      Versioning

      If versioning is enabled, you can specify a version ID for each object to delete so that these objects/delete markers of the specified versions can be deleted permanently. If no version ID is specified, a new delete marker will be created for the object.

      If a delete marker is created or deleted in this request, the &dxlt;DeleteMarker>true&dxlt;/DeleteMarker&dxgt; and &dxlt;DeleteMarkerVersionId&dxgt; nodes will be returned for this object.

      If an object of a specified version (including the delete marker version) is deleted permanently in this request, the &dxlt;VersionId&dxgt; node will be returned, indicating the version ID that is deleted in this request.
