<p>SOAP has been <a href="https://learn.liferay.com/dxp/latest/en/installation-and-upgrades/upgrading-liferay/reference/maintenance-mode-and-deprecations-in-7-3.html">deprecated in 7.3</a>, and I don't know if it was removed <a href="https://learn.liferay.com/dxp/latest/en/installation-and-upgrades/upgrading-liferay/reference/maintenance-mode-and-deprecations-in-7-4.html">in 7.4</a> already (not sure how to read the docs). &quot;Ctrl-F SOAP&quot;</p>
