# Granting Amazon ML Permissions to Output Predictions to Amazon S3
<a name="granting-amazon-ml-permissions-to-output-predictions-to-amazon-s3"></a>

 To output the results of the batch prediction operation to Amazon S3, you must grant Amazon ML the following permissions to the output location, which is provided as input to the Create Batch Prediction operation: 
+  **GetObject** permission on your S3 bucket and prefix. 
+  **PutObject** permission on your S3 bucket and prefix. 
+  **PutObjectAcl** on your S3 bucket and prefix. 
  +  Amazon ML needs this permission to ensure that it can grant the canned [ACL](https://docs.aws.amazon.com/AmazonS3/latest/userguide/acl-overview.html#canned-acl) bucket-owner-full-control permission to your AWS account, after objects are created. 
+  **ListBucket** permission on the S3 bucket. Unlike other actions, **ListBucket** must be granted bucket-wide permissions (rather than on the prefix). You can, however, scope the permission to a specific prefix by using a **Condition** clause. 

 If you use the Amazon ML console to create the batch prediction request, these permissions can be added to the bucket for you. You will be prompted to confirm whether you want to add them as you complete the steps in the wizard. 

 The following example policy shows how to grant permission for Amazon ML to write data to the sample location s3://examplebucket/exampleprefix, while scoping the **ListBucket** permission to only the exampleprefix input path, and granting the permission for Amazon ML to set put object ACLs on the output prefix:
