Possibility to start siren (Floodlight cam)

Hi together, is there any possibility to start the Ring siren with an external command? I have an smart home alarm system and I want to start the siren of the Floodlight Cam when the alarm inside the house is starting. So I have to talk with the floodlight cam, but how? Can I use something lika a webhook or an IFTTT integration? I hope, there is a possibility to manage this. Thank you very much!
