to determine if the change was made and should start an automation
Make sure that the “Last modified time” field only updates the value when the trigger changes (otherwise it will create a loop). Change the default option “All editable fields” to “Specific fields” and select the trigger.
Connect to your table and as a ‘Trigger field’ select created in previous step ‘Last modified time’ field.
Step 3 : Make a request
You will likely find that trying to download a file the first time its generated will take too long - and the download will fail. We need to send a request to start the image creation process. As a ‘URL’ use your image url.
Step 4 : Download the File
Once the process finished, Airtable will be able to download it from the same url.
Make sure you automation is on and triggers ‘At regular intervals’
Test the Automation
Now that the checkbox is checked, it updates the ‘Last modified time’ field and every 15 minutes make.com compares and detects changes. If changes are detected, make.com starts automation
