# 80609: Too Many Added Participants

Log Level: WARNING

## Description

This warning appears when you try to add more than two participants to a Proxy Session. Proxy supports one-to-one masked communication, and each Session can include only two participants.

### Possible causes

* Your application sent a create participant request for a Session that already has two participants.
* Your application tried to create a Session with more than two participant objects in the request.
* Your application is using a single Proxy Session for a workflow that needs more than two people, but Proxy Sessions are designed for communication between two parties.

### Possible solutions

* Check the existing participants in the Session before you add another one. Use the Participant list endpoint to confirm whether the Session already has two participants.
* If you need to connect a different pair of users, create a new Session instead of adding a third participant to the current Session.
* If one participant is no longer needed, delete that participant from the Session before you add a different participant.
* When you create a Session and include participants in the request, limit the Session to two participants total.
