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 if the request causes an object with the same name to be overwritten.

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.

¹⁰ This permission is only required when the request includes the query parameter allowNonEmpty=true.

¹¹ This permission is only required when the request includes the query parameter allowOverwrite=true and the request causes an object with the same name to be overwritten.

¹² This permission is only required when the request includes the query parameter copySourceAcl=true.

ACL-related methods
