This section provides instructions for an iOS developer to setup OneLink (deep linking and deferred deep linking) to work in the app.

There are several stages involved in the setup:

  1. Initial app setup
  2. Unified deep linking (UDL)
  3. Optionally extended deferred deep linking by using parts of the GCD API.

Note: Customers already using OneLink may be using the [legacy methods] ( for deep linking and deferred deep linking, instead of UDL.
