trigger at the update with integromat

Good morning,

I use this formula to send a push notification on my iPhone

let webhookURL := ""https://paste-your-webhook-url.here;
let data := {
RecordID: ID
};
http("POST", webhookURL, {
'Content-Type': "application/json"
}, data),

but it only works with a button, no way to do with the trigger at the update, someone would have an idea if the problem comes from this command or from my integramat scenario.

Thank you in advance
