Support for apple iOS universal links (deep links).


Companies that have custom iOS apps need to be able to support universal links (deep links). This is where a user gets a link (via email or through other means), taps on that link, and then iOS automatically opens the company app referenced in that link.


Currently, it's not possible with hubspot, because we cannot upload to the root folder. It's simple to fix, all that apple requires is for us to host a static json file at See apple documentation:


I asked support about this, and they agreed it's not currently possible, see


One possible solution: give us access to the /.well-known/ folder, without needing to give us access for the root folder.

I have come up against this same issue, not being able to upload an apple-app-site-association file means our iOS users can't have links open in their native apps.


As mentioned in the original post allowing uploads to a /.well-known/ folder would solve this issue and also be useful in other situations as well.

Hey! Has the universal link issue been looked into? It would also be important for Android. Our core product is a mobile app and the use case would be directing customers to specific places in our apps from our automation emails. 


A use case for us:

A customer searches for a rental property in multiple different locations in London & say has a high budget to spend on rent. We would recommend areas or properties which could also be of interest, based on our data. The CTA link would direct them straight there.

Hi Derek_Gervais,


I was unable to redirect the URL, it says "Reserved URL. The URL you used is reserved."


What I did was, I uploaded a json file in the HubSpot file directory, path is something like:



Then, I pasted the above URL in the original URL input field under Settings > Add URL Redirect, and input this URL below in the Redirect to input field:



Please let me know if I am missing something. Many thanks!

Hey @alponce


Is the original URL something you've copied directly from the file manager? It doesn't look exactly correct, but it's tough to say without seeing your account. The "Reserved URL" error generally occurs when the original & redirect URLs are swapped, or when there's already content at the Original URL.
