+description: A templated URL
+base_type: string
+layout: default
+source_label: OpenAPI
+source: https://spec.openapis.org/oas/v3.0.3.html#paths-object
+---
+
+# <a href="..">{{ page.collection }}</a>
+
+## {{ page.slug }} - {{ page.description }}
+
+Base type: `{{ page.base_type }}`.
+
+The `{{page.slug}}` format is a templated URL, as distinct from a URI Template. The string may contain unescaped `{` and `}` characters, but is not a full [RFC6570](https://www.rfc-editor.org/rfc/rfc6570) URI Template or a `uri-reference'.
+
+Usage is as per the [`paths` Object](https://spec.openapis.org/oas/v3.0.3.html#paths-object) in OpenAPI 2.0/3.x.
