Webhook creating label

I am a carrier looking at developing your Carrier Label Webhook. I have had your support team configure the webhook for us, but when receiving the webhook, we cannot see the API token in either the headers or body. Where can we expect to receive the token to authenticate the the request and customer sending it?

Hello, @jasongengshun! First, let me welcome you, glad to have you here!
Are you referring to the HMAC header? That header will be sent with the Generate Label Webhook payload if the “default” secret exists in: https://app.shiphero.com/dashboard/settings/api.
Can you confirm if it does on the affected account?
