If you or anyone in your organization are experiencing a webhook failure, it means that you went through the process of configuring the webhooks. You can review what a webhook is and how to set them up here.
When there is a webhook failure in an evaluation it will show a Pending Status and a purple banner will appear at the top of the screen for about 15 seconds. It will indicate which data service experienced the webhook failure.
Re-running the evaluation will typically resolve this issue. If there is any reason that does not work, then please reach out to the Alloy Support Team and we will help get to the root cause of the failure.
