The API is designed to be platform-agnostic. When new platforms launch, your existing integration patterns (threads, messages, prospects) will work the same way — the platform field on objects will reflect the new platform.

​
What “platform-agnostic” means for your code

The data model uses generic concepts that map across platforms:
Inbox conceptX (Twitter)InstagramLinkedIn
ThreadDM conversationDM conversationMessage thread
MessageDirect messageDirect messageInMail / message
ProspectX userInstagram userLinkedIn user
Account linkConnected X accountConnected IG accountConnected LI account
Code you write today against the X integration will require minimal changes when new platforms are available. The main difference will be the platform field value on API objects.
