+
+<!-- action schema generated by tfplugindocs -->
+## Schema
+
+### Required
+
+- `expires_at` (String) Expiration date of the snapshot in RFC3339 format (ISO 8601).
+- `instance_id` (String) MongoDB instance ID to snapshot. Can be a plain UUID or a regional ID.
+
+### Optional
+
+- `name` (String) Name of the snapshot. If not set, a name will be generated.
+- `region` (String) Region of the MongoDB instance. If not set, the region is derived from the instance_id when possible or from the provider configuration.
+- `wait` (Boolean) Wait for the snapshot to reach a terminal state before returning.
