Thought it would be helpful to mention that if you’re using tools like Integromat or Zapiar with Webflow, these tools often require Collection IDs and/or Item IDs to work with Webflow. If you restore your site from a backup all of your IDs will change and your Integromat and Zapiar scenarios will no longer work. This may be obvious to some, but man it completely bit me today!
You are correct and this has been mentioned before in the forums and there is this warning in the University on this page.
Important : When you perform a restore, all CMS Collection and item IDs will refresh. This refresh will affect API calls and third-party connections that use Collection or item IDs. You will need to reconnect them to the refreshed items. Please make sure you want to perform this action.
It’s a weak point in Webflow’s service. Thanks for sharing and sorry you had to learn the hard way.
