# 50417: Participants limit exceeded

Log Level: ERROR

## Description

The total number of participants in this conversation exceeds the limit.

### Possible causes

* You are trying to add more native Programmable Chat participants than allowed in this conversation. Maximum number of conversation participants is 100 by default, can be increased to 1000 programmatically.

### Possible solutions

* Increase the [maximum limit](/docs/chat/rest/service-resource#update-a-service-resource) by using Developer Console or REST API. Up to [1000 participants](/docs/conversations-classic/conversations-limits) are supported.
* Retrieve a [list of current participants](/docs/conversations-classic/api/conversation-participant-resource#read-multiple-conversationparticipant-resources) in this conversation and [remove](/docs/conversations-classic/api/conversation-participant-resource#delete-a-conversationparticipant-resource) the ones that are no longer required.
* Consider reusing participant identity across multiple clients, if user behavior is similar and data may be shared.
