How to delete google scripts ClockTrigger after it executes

Question

I have some code which needs to execute one function based on an hourly trigger, then another function exactly one hour after the first one. Like this:

function main() {
  firstFunction();
  ScriptApp.newTrigger('secondFunction')
  .timeBased()
  .after(60 * 60 * 1000) // 60 mins * 60 s * 1000 ms
  .create();
}

This is working fine. I just noticed though that the triggers build up in "my triggers" of the google apps script console. Is there any way to delete the trigger after execution?

Answer 1

After execution,

• get trigger id from event object

• delete the trigger associated with the id:

function secondFunction(e){
  ScriptApp.deleteTrigger(
    ScriptApp.getProjectTriggers().find(
      trigger => trigger.getUniqueId() === e.triggerUid
    )
  );
}
