When triggering a Make webhook (or any other GET webhook), you can’t place the Record ID immediately after the URL.
The Record ID needs to be designated as a URL parameter, which would make your final URL look something like this:
https://hook.us.make.com/abcdefg?RecordID=rec123456789
So, your formula in Airtable would look something like this:
"https://hook.us.make.com/abcdefg?RecordID=" & RECORD_ID()
Also, you can trigger a Make webhook from an Airtable automation using a script, which I explain in this thread: Instantly trigger a Make automation from an Airtable script
You can also see what a URL with parameters looks like there.
Hope this helps! If you’d like to hire an expert Airtable consultant to help you with anything Airtable-related, please feel free to contact me through my website: Airtable consultant — ScottWorld
