<h3 id="summary-problem-motivation">Problem/Motivation</h3>
<p>The way orchestration handles webhooks on remote platforms is that they can register webhooks with orchestration, containing their URL, requests requirements, and authentication details.</p>
<p>All registered webhooks are exposed to internal services like e.g. ECA who can post to each of them.</p>
<p>For platforms that Drupal hasn't developed a dedicated integration for yet, we at least want to ensure that their webhooks can be leveraged.</p>
<h3 id="summary-proposed-resolution">Proposed resolution</h3>
<p>Implement the UI in orchestration that allows the manual webhook registration with the details that a user may pick from their account on external platforms.</p>
