I found a similar unsolved discussion titled "Where do you get the user_id from?" which might be relevant to your issue [1].

To resolve the issue where the user_id does not update when switching users during a conversation in a chatbot iframe embedded on a website, ensure that both the user_id and conversation_id are obtained and passed correctly. When initializing the chatbot, use the chat-messages API endpoint to obtain these IDs together, as the iframe embedding generates a different user_id. You can pass dynamic parameters through the inputs field in the API request or the difyChatbotConfig object when using the iframe.

Example using the API request:

{
    "inputs": {"dynamic_param": "value"},
    "query": "Hello, how can I assist you?",
    "response_mode": "streaming",
    "conversation_id": "",
    "user": "abc-123"
}

Example using the difyChatbotConfig object:

window.difyChatbotConfig = {
    token: 'YOUR_TOKEN',
    inputs: {
        dynamic_param: 'value'
    }
};

Ensure that the user_id is updated correctly in these configurations when switching users [2].

I want to get user id from chatbot iframe embedded to my wordpress site via body tag:

<script> window.difyChatbotConfig = { token: 'CZCijLyaLL6RFV4X', baseUrl: 'http://****.**', systemVariables: { user_id: '2', }, } </script> <script src="http://ingpt.ir/embed.min.js" id="CZCijLyaLL6RFV4X" defer> </script> <style> #dify-chatbot-bubble-button { background-color: #1C64F2 !important; } #dify-chatbot-bubble-window { width: 24rem !important; height: 40rem !important; } </style>

can we use conersation_id in within chatbot iframe like:

systemVariables: {
user_id: '2',
conersation_id: '2'
},

@dosubot[bot] commented on GitHub (Apr 15, 2025):

To use conversation_id within the Dify chatbot iframe, you can include it in the systemVariables configuration. Here's how you can set both user_id and conversation_id:

<script>
 window.difyChatbotConfig = {
  token: 'CZCijLyaLL6RFV4X',
  baseUrl: 'http://****.**',
  systemVariables: {
   user_id: '2',
   conversation_id: '2'
  },
 }
</script>
<script
 src="http://ingpt.ir/embed.min.js"
 id="CZCijLyaLL6RFV4X"
 defer>
</script>
<style>
  #dify-chatbot-bubble-button {
    background-color: #1C64F2 !important;
  }
  #dify-chatbot-bubble-window {
    width: 24rem !important;
    height: 40rem !important;
  }
</style>

Make sure that the conversation_id is correctly managed and updated as needed, especially when switching users or starting new conversations. This setup should help in maintaining the correct session and user context within your WordPress site.

@crazywoola I just tested using the newest version (1.3.0) and this is not working yet. I send user_id and conversation_id, but chat is loaded as a new one. I also tested using a chat created after updating to newest version.

Do you have any ideas about possible issues?
