Zap not triggering for new webhooks sent

h team

I have created a ZAP which should run a triggert by a webhook. 

after subscription i got the hook url

as i run the following code (same from postman) i can see the hook in the monitor but nothing actually happned in the zap (emai/goolge sheet) 

am i missing something?

await fetch("https://hooks.zapier.com/hooks/standard/5461766/f82abd556c744950bb4804b049a13eda", 
    { method: "POST", 
      body: ' {"id":20829875,"name":"M","firstname":"m","lastname":"w","company":"S","phone":"","title":"d","location":"usa","email":"xxx"}]',
      headers: { "Content-Type": "application/json", Accept: "application/json", } });
