Resuming Chats

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.

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:

   Chat metadata

   1
   {
   2
     "type": "chat_metadata",
   3
     "chat_group_id": "8859a139-d98a-4e2f-af54-9dd66d8c96e1",
   4
     "chat_id": "2c3a8636-2dde-47f1-8f9e-cea27791fd2e"
   5
   }

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

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

   Next.jsTypeScriptPython

   1
   "use client";
   2
   import { VoiceProvider } from "@humeai/voice-react";
   3
   4
   export default function ClientComponent({
   5
     accessToken,
   6
   }: {
   7
     accessToken: string;
   8
   }) {
   9
     return (
   10
       <VoiceProvider 
   11
         auth={{ type: "accessToken", value: accessToken }}
   12
         resumedChatGroupId='<YOUR_CHAT_GROUP_ID>'
   13
       >
   14
         // ...etc.
   15
       </VoiceProvider>
   16
     );
   17
   }

   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.
