Connections and Relationships Feature for Messaging ---- 2 min read makes it super easy to build, launch and run Chat in your Apps, whatever be your use-case. For 1-1 Chats, following are the most common ways to lead users to conversations:

  • Button on Profile: Example, “Message” button on profile of a service provider the member has booked.
  • Button on Listings: Example, listing of sellers with a “Message Seller” button for each listing.
  • “Contacts” or “Connections” Screen: Showing other users with whom the user is most likely to initiate conversations with.
  • “Recent” Screen: Showing recent conversations of the user.
  • Automatically creating a conversation based on actions and events in your app, and opening the conversation screen.


Depending on your use-case, you might have one or more of the above ways in your app for triggering conversations, and leading users to them. In this article, we will talk about the third method above, in which you can have Connections or Friendships between members.




Connections can be interpreted as: Users that are easily accessible to chat

When would Connections Feature be useful for your App

In many use-cases, users would have a subset of other users who they’re most likely to start a conversation with. This is especially relevant in Social Networking, Dating, Niche Communities, etc, or cases like:

  • An Education App where a Teacher would have all their students’ parents as contacts.
  • An Enterprise Work Management App where a Supervisor would have all Experts as contacts.
  • A Home Rental App where a Home Owner can have users who’ve recently booked their property as contacts.
  • A Team Communication App.

and so on…

The “Connections” or “Friendships” or “Contacts” feature of Channelize helps in achieving the above very easily. Connections can be formed or updated via API based on the logic, actions and events of your platform. supports 2 types of connections:

  • Follow (One-way relationships): A follows B => B will appear in the “Following” list of A.
  • Friend (Two-way relationships): A & B are friends => Both A & B will appear in each others “Friends” list. provides pre-built screens for “Connections” / “Contacts” in the SDKs for Javascript, iOS & Android. By default, these screens show Online Contacts first in order. Some other pre-built screens / features that use “Contacts” are:
