Get alert method with authentication for the receveing endpoint

Hello, I have the following doubt.

I have an alert that uses the get method to notify my API that a task has ended. All this using python-gvm.
However, this only works if this endpoint is “insecure”. [Aka the whole internet can send a get request successfully]. I would like to know if in GMP7 / 8 there is an authentication/basicauth mechanism that is “sent” with the guet request or other process ? In order to receive alerts only from trusted users.
After rereading the documentation I didn’t find any mechanism that allows this.

Thank you
