### Overview

Create a new API from the [OpenAPI](https://spec.openapis.org/oas/latest.html) specification given.
See the [API Catalog documentation](https://docs.datadoghq.com/api_catalog/add_metadata.md) for additional
information about the possible metadata.
It returns the created API ID.

This endpoint requires the `apm_api_catalog_write` permission.

OAuth apps require the `apm_api_catalog_write` authorization [scope](https://dnd37xeb23o8n.cloudfront.net/stefon.simmons/docs-astro-web-10435/api/latest/scopes.md#api-management) to access this endpoint.
