 The following arguments are supported:
 
 - `secret_id` - (Required) The ID of the secret associated with the version.
-- `data` - (Required) The data payload of the secret version. Must not exceed 64KiB in size (e.g. `my-secret-version-payload`). Find out more on the [data section](/#data-information).
+- `data` - (Optional) The data payload of the secret version. Must not exceed 64KiB in size (e.g. `my-secret-version-payload`). Only one of `data` or `data_wo` should be specified. Find out more on the [data section](/#data-information).
+- `data_wo` - (Optional) The data payload of your secret version in [write-only](https://developer.hashicorp.com/terraform/language/manage-sensitive-data/write-only) mode. Must not exceed 64KiB in size (e.g. `my-secret-version-payload`). Only one of `data` or `data_wo` should be specified. `data_wo` will not be set in the Terraform state. To update the `data_wo`, you must also update the `data_wo_version`. Find out more on the [data section](/#data-information).
+- `data_wo_version` - (Optional) The version of the [write-only](https://developer.hashicorp.com/terraform/language/manage-sensitive-data/write-only) data. To update the `data_wo`, you must also update the `data_wo_version`.
