HTTP Sensor with Auth-Token too long for my ALP 600-Doorbell

Bom Dia Community!
I try to set up a ALP 600 Doorbell that is capable of sending HTTP-Post in case of events. My problem is, the generated token from HA is too long for the config-field of the ALP600. As I’m quite new to HA, my question: Is there a way to set or provide a shorter token ( < 100 ) for my purpose or to authenticate user/pass ? Greetings, Gregor
Pic form config-page ALP600:

try to install n8n with the following repository:
N8n.io integration (GitHub - Rbillon59/home-assistant-addons: Repository of self made addons)
In n8n you are allowed, to define your own webhook (with own auth) and you could forward it to home assistant.
That is for me the best solution, because I can modify everything :wink:
