Enable text formatting for your customer's chat experience - Amazon Connect

Enable text formatting for your customer's chat experience

With Amazon Connect message formatting, you can enable your customers and agents to quickly add structure and clarity to their chat messages.

You can provide the following types of formatting on both the chat user interface and the agent application using markdown:

How to enable message formatting

  1. When you create a new chat user interface, rich text formatting is enabled out of the box. No additional configuration is required.

  2. To add text formatting capabilities to an existing chat user interface, update the chat widget code with the following code that is highlighted in bold:

    (function(w, d, x, id){ s=d.createElement('script'); s.src='https://d3xxxx.cloudfront.net/amazon-connect-chat-interface-client.js'; s.async=1; s.id=id; d.getElementsByTagName('head')[0].appendChild(s); w[x] = w[x] || function() { (w[x].ac = w[x].ac || []).push(arguments) }; })(window, document, 'amazon_connect', 'widget-id'); amazon_connect('styles', { openChat: { color: 'white', backgroundColor: '#123456'}, closeChat: { color: 'white', backgroundColor: '#123456'} }); amazon_connect('snippetId', 'snippet-id'); amazon_connect('supportedMessagingContentTypes', [ 'text/plain', 'text/markdown' ]);

    The code that is highlighted in red is set to the correct values when you get the snippet from the Amazon Connect console. The only content you choose to add or remove is the last line in bold for supportedMessagingContentTypes.

  3. To add text formatting capabilities to your own custom chat user interface (for example, Chat Interface or your own UI solution on top of ChatJS), follow these steps:

    1. Call the StartChatContact API. When calling StartChatContact, add the SupportedMessagingContentTypes parameter as shown in bold in the following example:

      // Amazon Connect StartChatContact API { "Attributes": { "string" : "string" }, "ClientToken": "string", "ContactFlowId": "your flow ID", "InitialMessage": { "Content": "string", "ContentType": "string" }, "InstanceId": "your instance ID", "ParticipantDetails": { "DisplayName": "string" } // optional "SupportedMessagingContentTypes": [ "text/plain", "text/markdown" ] }
    2. Import chatjs as an object, as shown in the following example:

      import "amazon-connect-chatjs"; this.session = connect.ChatSession.create({ ... }); this.session.sendMessage({ message: "message-in-markdown-format", contentType: "text/markdown" });

      If you don't use ChatJs, see these topics for information about sending markdown text through Amazon Connect APIs: StartChatContact and SendMessage.

    3. Send messages with markdown. See the previous code snippet for importing chatjs as an object for an example of how to send messages. You can use simple markdown for formatting text in chats. If you're already using chatjs today to send plaintext messages you can modify your existing logic to call SendMessage with text/markdown as contentType instead of text/plain when you want to send markdown messages. Be sure to update the sendMessage parameter to have the markdown format of your messages. For more information, see Markdown Guide Basic Syntax.

    4. Implement your own logic in the UI package to render markdown messages in the input area and chat transcript. If you use React, you can use react-markdown as a reference.


Text formatting capabilities appear to your agent only if the feature has been enabled for your customer in the chat user interface. If text formatting is not supported or enabled on the customer chat user interface, the agent will not have the ability to compose and send messages with text formatting.
