In short: A Mumble chatbot is built from nodes. Each node is one step: a message, a choice, a handoff to an agent, a call to another system or an AI step. Drag nodes from the left sidebar onto the canvas and connect them.
The node types
| Node | What it does |
|---|---|
| Standard message | Sends text. Only inside the 24-hour window. |
| Template message | Sends an approved template. Works outside the window too. |
| Menu message | A list the customer taps. Best for 4 or more options. |
| Button message | Up to 3 reply buttons. Each button leads to its own next node. |
| Media message | Sends an image, video, document or audio file, with a caption. |
| Agent | Hands the chat to an agent or team. The bot stops replying. |
| Chatbot | Moves the customer to another bot in your account. |
| HTTP request | Calls an outside system, such as a store or CRM, and uses the answer in the flow. |
| AI | Runs Dolores AI as one step, then the flow continues. |
The main node is the bot’s starting point. It receives the customer’s first message and is set automatically.
Good to know
- Two kinds of variables: templates use numbered variables (
{{1}},{{2}}). Canvas messages use named ones ({{first_name}}). Don’t mix them up. - Menu preview: in Mumble the menu looks like plain text. On the customer’s WhatsApp it’s a real tappable menu.
- HTTP errors: click Logs in the bottom toolbar to see each request and response.
- AI node: available from the Pro plan. Each run uses 1 AI credit.
Actions on every node
Each node has an Actions panel that runs when the customer reaches it:
- Continue to the next message? Move on without waiting for a reply.
- Add customer to a list or Change customer status.
- Turn off the bot for the customer, for example at the end of a flow.
- Save point: after a reset, the customer returns here instead of the start.
- Save the customer’s message: store the reply in a variable to use later, such as a name or order number.
Your plan’s chatbot steps
Your plan limits how many nodes you can build across all your bots, not how many times they run: Standard 25, Pro 100, Scale 500. When you reach the limit, you can’t add nodes, duplicate a bot or import a bot template. Extra nodes cost $1 each. See the pricing page.
Messages the bot sends are billed by Meta like any other message. See Paying Meta and WhatsApp Messaging Costs.
Common questions
A standard message wasn’t sent
The customer’s 24-hour window is closed. Use a template message node instead.
The bot goes back to the start every time
Add a save point on the node the flow should resume from.
The customer got {{1}} instead of a value
You used the wrong kind of variable. Use numbered variables only in templates and named ones in canvas messages.
A template doesn’t appear in the node
Only approved templates are listed. Check its status on the templates page.
