Resuming Chats | Hume API

EVI supports reconnecting to an ongoing chat session, preserving all prior conversation context. This is especially useful in cases of unexpected network failures or when a user wishes to pick up the conversation at a later time, enabling continuity without losing progress.

If data retention is disabled, the ability to resume chats will not be supported.

Resuming a chat

See steps below for how to resume a chat:

  1. Establish initial connection: Make the initial handshake request to establish the WebSocket connection. Upon successful connection, you will receive a ChatMetadata message:
   {
        "type": "chat_metadata",
        "chat_group_id": "8859a139-d98a-4e2f-af54-9dd66d8c96e1",
        "chat_id": "2c3a8636-2dde-47f1-8f9e-cea27791fd2e"
   }

  1. Store the ChatGroup reference: Save the chat_group_id from the ChatMetadata message for future use.

  2. Resume chat: To resume a chat, include the stored chat_group_id in the resumed_chat_group_id query parameter of subsequent handshake requests.

"use client";
import { VoiceProvider } from "@humeai/voice-react";

export default function ClientComponent({
     accessToken,
}: {
     accessToken: string;
}) {
     return (
       <VoiceProvider
         auth={{ type: "accessToken", value: accessToken }}
         resumedChatGroupId='<YOUR_CHAT_GROUP_ID>'
       >
         // ...etc.
       </VoiceProvider>
     );
}

When resuming a chat, you can specify a different EVI configuration than the one used in the previous session. However, changing the system prompt or supplemental LLM may result in unexpected behavior from EVI.
