User Scenario

Let us consider an extension integrating GitLab and Cliq. The webhooks created during installation can be deleted using the uninstallation handler. This handler does an entire clean up once the extension is uninstalled, thereby ensuring the privacy and security  of your extension data. The sample code snippet is given below. 


getProjects = invokeurl
[
	url :"https://gitlab.com/api/v4/projects?visibility=private&simple=true"
	type :GET
	connection:"ENTER THE CONNECTION NAME"
];
for each  project in getProjects
{
	projectID = project.get("id");
	webhooks = invokeurl
	[
		url :"https://gitlab.com/api/v4/projects/" + projectID + "/hooks"
		type :GET
		connection:"ENTER THE CONNECTION NAME"
	];
	for each  webhook in webhooks
	{
		if(webhook.get("url").contains("https://cliq.zoho.com/api/v2/applications/"APP-ID"/incoming"))
		{
			deleteWebhookId = webhook.get("id");
			deleteWebhook = invokeurl
			[
				url :"https://gitlab.com/api/v4/projects/" + projectID + "/hooks/" + deleteWebhookId
				type :DELETE
				connection:"ENTER THE CONNECTION NAME"
			];
		}
	}
}
