I have ads-script that writes to a spreadsheet but doesn't trigger a simple or a installable onChange event.
Only when I edit the spreasdheet myself this is triggered. Is there any way I can trigger onChange or other simple/custom trigger by an external ads script?
Based on official documentation event-driven triggers run when a user modifies the structure of a spreadsheet itself. So in this case if the Ads Script modifies the Sheet it will not trigger.
A workaround would be to have an Apps Script run a time-driven trigger to check for any changes and continue with the process when changes are detected.
You may accomplish this with a script. You can save the last modified date, if you set triggers for every minute, next minute checks if the modified date is greater than the last one.

I am using the Add-on Scan-IT to Sheets to input inventory info - I need the function I have coded to run after every scan. The problem is, when the scan is populated to the sheet it does not trigger the onEdit or onChange.
Any advice is greatly appreciated!
No trigger activates with a change made by a script or addon. As you can read on Triggers Restrictions: «Script executions and API requests do not cause triggers to run». So, it is not possible to use them in your situation.
As a workaround you can use time triggers to run your function, or just run them manually.
I've built a spreadsheet that tracks form responses using the onSubmit trigger. This works well. I then want to display part of the spreadsheet on another spreadsheet, and have built a script that does this.
In order to ensure the second spreadsheet is dynamically updated and synchronised with the first, I have tried to use the onEdit installable trigger; however, it does not work when it is programmatically edited, only if I manually edit spreadsheet 1. Any solutions?
Triggers do not fire on the spreadsheet changes made by scripts. I think the idea is that the script making changes can also follow through on any consequences of those changes. In your case, I see three solutions:
If you just want to "display part of the spreadsheet on another spreadsheet", then importrange command suffices, you don't need a script to do that.
The function triggered by form submission can modify the target spreadsheet itself. To do this, you need an installable trigger running on form submission, since simple triggers cannot access other spreadsheets.
If you really want to trigger a function in a script attached to another spreadsheet, you can run a time-based trigger that will check the last-updated time of the spreadsheet.
Example of #3: a function that can be set to run every 5 minutes, to detect changes of any kind.
function checkForUpdates() {
var updated = DriveApp.getFileById(SpreadsheetApp.getActiveSpreadsheet().getId()).getLastUpdated();
if (new Date() - updated < 300000) {
// updated in the last 5 minutes, do something
}
}
I wrote a small script bound to a Google spreadsheet that reads an email-address from a cell in the last row and sends an email to it.
The values are collected by a WebApp (not by Google form).
I tried all kind of triggers. The time driven triggers work, but the spreadsheet triggers don't work. I tried all of them. If I change manually some cell in the spreadsheet the onEdit trigger is working, but it doesn't fire up when the sheet was changed by another script.
Google's dev says : The onEdit() trigger runs automatically when a user changes the value of any cell in a spreadsheet. but it doesn't precise the change could be from script or not.
You'll find here a comment from HDCerberus :
I'm not at my PC to write a full response, but at a glance it could be the OnEdit trigger, which ONLY works when the sheet is edited manually, and NOT by a script. Are you expecting it to run when the sheet is edited manually or by a script?
Not every change triggers onEdit(). Please take a look on answer from topic Detect user inserting row or column in a google spreadsheet and reacting in a script - you will find registered bugs and one of them says that values written by scripts do not trigger onEdit().
I have a google application script that changes a value in A1 in onLoad event in a spreadsheet. This triggers a cascade of changes. I would like to detect the event when let's say cell F200 is changed because of the edit to cell A1. How do I set up the triggers to detect this change?
An installable open trigger runs when a user opens a spreadsheet, document, or form that he or she has permission to edit.
An installable edit trigger runs when a user modifies a value in a spreadsheet.
An installable change trigger runs when a user modifies the structure of a spreadsheet itself — for example, by adding a new sheet or removing a column.
An installable form-submit trigger runs when a user responds to a form. There are two versions of the form-submit trigger, one for Google Forms itself and one for Sheets if the form submits to a spreadsheet.
I'm playing with triggers.
In a spreadsheet, I have a function that inserts a date in a new row. Runs as a clock trigger every minute. Works fine if the spreadsheet is open or closed (loving that part).
In a standalone script, I setup a trigger for onEdit in the above spreadsheet. All it does is email me the e.value.
It works if I'm in the spreadsheet and just type in some characters in a cell.
What I'd "expect" is each time the date is inserted by the first trigger, it would trip the onEdit. Alas, it does not. Even if I run the insert date function outside of the trigger, my email onEdit trigger does not fire.
Any thoughts?
I ask, as my goal was to have scripts updating a sheet that kicked off an onEdit event.

UPDATE #1:
Maybe this code example helps?
I simplified this to one script inside a spreadsheet container. Each function works fine on their own and the second works if I do any interactive changes to the spreadsheet.
This is just exploration, so please ignore quota's or the utter nonsense of what I'm testing here :-)
insertClockTrigger: runs every minute, works fine
installableOnEdit: never triggers as an installable onEdit when insertClockTrigger fires
I'm curious why what looks to be an edit done by the insertClockTrigger is not firing an onEdit trigger. Do triggers not trigger triggers (could not help myself!)?
function insertClockTrigger() {
var sheet = SpreadsheetApp.openById('spreadsheet-ID').getSheets()[0];
var nDate = new Date();
sheet.getRange(sheet.getLastRow()+1,1,1,1).setValue(nDate).flush;
}
function installableOnEdit(e) {
GmailApp.sendEmail("some#email.com", "Test trig2", "FISH: "+e.value);
}
Call the onEdit function from the clock trigger function.
Also, you might hit a quota issue with running such a trigger every min.
Think I found an answer.

Yes, "on edit" events are not called when the changes are made from
the code, they're are called only for manual changes. This behaviour
is intended by design, as to avoid unnecessary recursion problems.
Also, it just too easy to just call your desired on-edit function
directly from your code. i.e. when you script that inserts a new
ticket does so, it can just plainly call your "fundEmail" function,
there's no need for another trigger.
onEdit should be renamed to onUserEdit. It doesn't receive system changes, only direct user edits.
I haven't tested this, but onChange may do what you want.
