Is it possible to remove the user's button selection from the list or quick replies in chatbot?

No. Every message exchanged between a bot, users, and agents needs to be tracked/recorded so that the users are aware of the message sent/selection made. Following are the reasons:
• Providing feedback: When a user selects an option/sends a message, they expect feedback in response. By displaying the messages, users will know that their message has been received.
• Transparency: When a user message is displayed, it builds trust between the user and the chatbot.
• Clarification: At times, the bot may not understand the context of the user's message. Displaying the message in such instances will be essential.

Why does a blank space appear when scrolling in the widget?

This happens only for bots migrated from V1 ("app.yellowmessenger.com" or "app.yellow.ai" platform) to V2 (cloud.yellow.ai platform).

The bot name and description text color is set automatically based on the background color to ensure readability, with a contrast ratio of 4.5+. For example, white text on bright red background is hard to read, so text color is set to black. Slightly darker red shades can be tested to find a readable color combination.

Is it possible to deploy a bot in multiple locations on a website or Mobile SDK?

For web bots, it is not possible to have two bots on the same window simultaneously. However, you can load a default bot initially, and then when a user selects a specific order in which the bot needs to be deployed, you can trigger a new bot using the following code.

window.YellowMessengerPlugin.init({bot: '<botId>'})

Note that, this will replace the previously loaded bot. On Mobile SDK, if you want to maintain a separate session and history for each order, you need to pass the ymAuthToken parameter. Ensure that these approaches allow you to manage different instances of the bot, but only one bot can be active at a time.

How long will the session be active in the chat widget?

The session in the chat widget will remain active for 24 hours by default. However, if needed, you have the flexibility to customize the session duration from the backend. The session duration can be adjusted within a range of 1 minute to 1440 minutes, which is equivalent to 24 hours.
By configuring the session duration according to your specific requirements, you can ensure that users have an adequate amount of time to interact with the chat widget before the session expires.

How to hide the home and input buttons when the user opens the chatbot for first time?

To hide the home and input buttons when the user opens the chatbot, add the setDisableActionsTimeout property inside the window.ymConfig object.

Is it possible to prevent the bot icon from overlapping with CTAs on mobile screens?

The following are the two options to prevent the bot icon from overlapping:
1.Write a custom script to override the position.
2. Hide the default icon and create a custom entry point or button on the site. Use the window.YellowMessengerPlugin.openBot() function to open the bot when a user clicks on the custom button. For more information, click here.

Can the Bot title, description and logo can be changed dynamically based on website?

Yes, you can configure different themes for different websites. Set a default theme in Channels > Chat Widget > Widget Panel/Bot icon. Then, based on the user, you can override it on the web and mobile SDK. For the web, you need to pass the following values inside window.ymConfig in the bot script:

`theme: {
  botName: "", // Text up to 50 characters
  botDesc: "", // Text up to 50 characters
  primaryColor: "", // RGB or HEX value
  secondaryColor: "", // RGB or HEX value
  botIcon: "", // CDN link
  botClickIcon: "" // CDN link
}

For the mobile SDK, you need to send the values as mentioned below:

let theme = YMTheme()
theme.botName = ""
theme.botDesc = ""
theme.primaryColor = ""
theme.secondaryColor = ""
theme.botIcon = ""
config.theme = theme

Note: botClickIcon is not applicable for Mobile SDKs since the entry point will be set within the app. On the website, botClickIcon refers to the floating icon displayed when the bot is minimized.

Is it possible to share the same chat session history across PWA and mobile SDK if a script is used to integrate the chatbot?

On PWA, you can use the same ymAuthenticationToken that you used on the mobile SDK. You can add the same ymAuthenticationToken at the end of the PWA URL to get the same chat session history.

 https://cloud.yellow.ai/pwa/v2/live/<your_bot_id>?ymAuthenticationToken=<your_user_token>

If a script is used to integrate the chatbot, you need to pass the token inside `window.ymConfig` in the script.

window.ymConfig = {

  ymAuthenticationToken: "your_unique_token"

}

How do we add ymAuthenticationToken to the PWA script so that we can see the same chat history in the PWA and mobile SDK?

You need to pass the ymAuthenticationToken in the URL as a query parameter.

https://cloud.yellow.ai/pwa/v2/live/<your_bot_id>?ymAuthenticationToken=<your_user_token>

General FAQs
