​
Path Of A Message

1

Customer Texts Your Number

The customer sends an SMS to the number you registered in your OpenCX dashboard.
2

Message Delivered To OpenCX

The message is delivered to OpenCX and validated.
3

Match Number To Org

OpenCX matches the receiving number to your org.
4

Find Or Create Session

The sender’s phone number is matched against existing contacts. If a contact has an open SMS session, the message continues it. If the contact exists but has no open session, a new session is created. If no contact record exists, a new session and contact are created automatically.
5

AI Generates Reply

If is enabled for SMS, the AI generates a reply using your configured knowledge and tools. The reply is sent as plain text. When Autopilot is off or the session is handed off, no AI reply is generated — human agents reply from the inbox instead.
The thread in your OpenCX dashboard is the authoritative record. SMS has no subject-line tokens or threading headers — continuity is by phone number and open session status.

​
Outbound Format

All outbound SMS replies are plain text. Before sending, OpenCX strips HTML tags and code blocks. The cleaned message is sent through the SMS provider.
