Automation Rules do not call the URL for callback

I created a Role so that when an order is created and a product has a tag it calls a callback to send the created order as posted here:
https://developer.shiphero.com/webhooks#ar-webhook

When the order is created, the logs record that the rule was activated:

02/18/2025 12:22 PM Automation Rules We turned operator hold on from automation rule “My rule”

But after that no callback and call. The url is registered and running with ngrok.

Should I add something or for sandbox these callbacks are not available?

Hello @Rhaymison!
Thank you for being so patient. Can you share the order ID and endpoint URL? Feel free to do so privately if you prefer.
Have a great day!
