Homey is supposed to call via clicksend - what does the webhook look like?

Hi,

As of October 1, 2025, smsflatrate.net is shutting down its private service.
Now I’ve found clicksend, which also offers similar services.
So, homey is supposed to send an alert to clicksend via webhook, and this service then calls me via TTS.

I created an account there and have €2 free to try it out.
It doesn’t sound like much, but a TTS call (to a mobile phone) costs just €0.0737.
(€0.0129 per TTS call to a landline)
… also much cheaper than with smsflatrate.

I sent a test TTS call to the mobile phone from the clicksend dashboard, and it arrived promptly.

Now for my problem.
What does the webhook I want to send from homey look like?
The old one looked like this:

https://www.smsflatrate.net/schnittstelle.php?key=46#########b6c91c49&from=homey&to=0049176#####7&text=Achtung+Rauch+im+Heizungsraum++++Achtung+Rauch+im+Heizungsraum&type=30

The new one should start like this(?):

https://rest.clicksend.com/v3/voice/send …

I have my API key, language, voice, phone number, and alarm text—but how do I link them?
Does anyone have an ID? I’ve already contacted support, but unfortunately, I only got a link to help. I guess I’m just being stupid again. :face_with_spiral_eyes:
