Add webhook programmatically Episerver Form

Today I needed to add a webhook on creation on all forms by default. This shows you how.

Episerver.CMS 11, Forms v4

In an InitializationModule:

public void Initialize(InitializationEngine context)
    IContentEvents events = ServiceLocator.Current.GetInstance();
     events.CreatingContent += SetWebhookOnForms;

private void SetWebhookOnForms(object sender, ContentEventArgs e)
    //getting webhookurl from appsettings
    var webhookurl = ConfigurationManager.AppSettings["Webhook:forms"] + "";
    if (!String.IsNullOrEmpty(webhookurl) && e.Content is FormContainerBlock formContainerBlock)
        List webhookActorModels = formContainerBlock.Content.Property.GetPropertyValue>("CallWebhookAfterSubmissionActor").ToList();
        var customWebhook = new List();

        if (webhookActorModels == null || webhookActorModels.Count() == 0)
            webhookActorModels.Add(new WebhookActorModel
                BaseUrl = webhookurl,
                PostDataInJsonFormat = true

        formContainerBlock.Content.SetPropertyValue("CallWebhookAfterSubmissionActor", webhookActorModels);

There you got it, self explanatory
