Webhook - Where to find error codes

Webhook - Where to find error codes

Hey there!  I've created a webhook and have proved that my rule is firing.  However, it doesn't look like my webhook is being called.  I've taken a look at documentation that says that, if it errors, it will be displayed in the Zoho CRM.  But, where in Zoho CRM will the error codes be shown?  I can't find them.  I am referring to https://www.zoho.com/crm/help/automation/webhooks.html#Refer_Error_Codes .

thanks,
