I've successfully created a backend service to update shared folder member access to view only; however, the the shared folder link is still set to Edit access. I thought using the https://api.dropboxapi.com/2/sharing/modify_shared_link_settings endpoint would do the trick passing in the following parameters:
{
"settings": {
"requested_visibility": "public",
"audience": "public",
"access": "viewer"
},
"remove_expiration": false
}
Folder still shows edit access however for the shared link
