| > **{% data variables.release-phases.retired_caps %} Notice:** Authenticating to the {% data variables.product.prodname_dotcom %} API is no longer accessible using query parameters. Authenticating to the API should be done with [HTTP basic authentication](/rest/overview/authenticating-to-the-rest-api#using-basic-authentication). For more information, including scheduled brownouts, see the [blog post](https://developer.github.com/changes/2020-02-10-deprecating-auth-through-query-param/). | |

| > Authentication to the API using query parameters while available is no longer supported due to security concerns. Instead we recommend integrators move their access token, `client_id`, or `client_secret` in the header. {% data variables.product.prodname_dotcom %} will announce the removal of authentication by query parameters with advanced notice. {% endif %} | |
