How to create Webhook to retrieve record that changed in QuickBase

Matthew, Can you explain what you intend to do with the changed records? Automations, Webhooks, Actions and email notifications are all designed to work with such records. The difference is what you intend to do with them. Not all APIs require you to specify a record id. The API you need to use in the message body, depends on what you intend to do. As for Dan's solution, for it to work, you need to uncheck the box for "Hide the new/updated icons for all users". It is checked by default. This is available on your app properties page.
