+Learn more about the [basics of authorization]({{site.fundamental_docs}}/authorization/), or dig into the details of [Auth API]({{site.authapi_docs}}/), if you want to know more about this part of CARTO platform.

+The examples in this documentation may include a placeholder for the API Key. Ensure that you modify any placeholder parameters with your own credentials.
