IAM permissions for JSON methods

The following table lists the Identity and Access Management (IAM) permissions required to run each Cloud Storage JSON method on a given resource. IAM permissions are bundled together to make roles. You grant roles to users and groups.

For additional methods that only apply to buckets with Uniform bucket-level access disabled, see the ACL methods table.

1 If you use the userProject parameter or the x-goog-user-project header in your request, you must have serviceusage.services.use permission for the project ID that you specify, in addition to the normal IAM permissions required to make the request.

2 This permission is only required if you want to include ACLs or IAM policies as part of a full projection. If you don't have this permission and request a full projection, you receive only a partial projection.

3 This permission is only required when the request includes the enableObjectRetention query parameter.

4 This permission is only required if you want to include ACLs as part of the response.

5 This permission is required if you want to include ACLs or changes to the public access prevention setting as part of the request.

6 This permission does not apply to buckets with uniform bucket-level access enabled.

7 This permission is only required when the inserted object has the same name as an object that already exists in the bucket.

8 This permission is required when the request body includes the retention property or when making an UPDATE request for an object that has an existing retention configuration.

9 This permission is only required when the request includes the query parameter overrideUnlockedRetention=true.

ACL-related methods

The following table lists the IAM permissions required to run JSON methods that apply specifically to the management of ACLs. These methods only apply to buckets that have Uniform bucket-level access disabled.
