Why are there instances when our users suddenly disconnected to any App in our Marketplace?
It may be possible for users' connected devices to be disconnected automatically from the Validic marketplace. Typically, to disconnect a device from the marketplace, a user would go to the marketplace (the connected devices list in your site) and trigger a disconnect option, provided this feature was made available for your users. However, a user may also be able to go to a device's website or mobile app and from there, they can elect to remove the authorization they have provided to us when they connected their device in the marketplace. This causes our system to detect an unauthorized message from the source API whenever we check for data, and given that our access to the user's data is already unauthorized, we then mark the user's connection as disconnected.
To resolve this, your system may try to sync up the users' connection status with our API by making an Apps.json call (please see our API Doc for more technical information and our synced apps KBA for additional reference). This will allow your system to confirm whether your users' apps are still connected.
