Data security is a massive priority here at Merge, and we know it is for our customers too! This is why we added the ability to sync only the data you need and avoid storing any data you do not want passed through Merge.
How do I check what data is passed through Merge?
You can check out the Common Models tab in the Configuration section of your Merge app, where you can set what data you want to sync via Merge at the common model or field level!
What if I want to disable certain fields when linking with Merge?
We understand if your customers have any concerns about sharing sensitive user information with Merge. When setting up Service User permissions, you can toggle some fields that you wish to mask from Merge, and this will not affect your integration!
