What is Federation:
One of the features of Skype for Business (Lync) is Federation – which is the ability to  connect and communicate with Skype for Business (Lync) users in other organizations. You can let people that are using Skype for Business contact Skype for Business users from outside your organization and add them to their list of Skype for Business contacts. After they add them to their contact list, they can see if they are online and IM with them, hold meetings and share desktops.

Since WebChat is a Skype for business service hosted in our environment. You would need to have open federation with our organization. To learn more about federation you can find this information on the Skype for Business website:
