Let an AI Sales Agent Research the Answer Without Letting It Send

A customer writes: “How much are two portrait sessions?”

A rigid bot looks for the word “portrait” and sends a stored sentence. This Flow does something more useful. It reads the current message and a limited amount of conversation context, decides which business tools it needs, looks up the published offer, checks the relevant policies, calculates the total and produces a proposed reply.

For the tested example, the agent called the offer, policy and calculator tools and returned €180 for two sessions. It also asked for the missing booking detail instead of inventing one.

Then the Flow stopped. It did not send the reply.

That last step is deliberate. The workflow below is a read-only integration draft for testing an agentic sales assistant with your own business rules. It gives you the reasoning outcome, the tool calls and the proposed next action while keeping every customer-facing effect disabled.

What you get after importing it

The workflow has four practical layers:

1. Trusted input. The Wassenger trigger supplies message and device identifiers. Native Wassenger nodes reload the actual message, recent history, contact and chat state.
2. Bounded context. Code nodes remove private notes, events and unrelated contact fields before the conversation reaches the model.
3. An agent with five tools. The model can consult offers, policies, recent history and the allowed contact fields, or calculate an amount from a published price.
4. A safe preview. The Flow validates the proposed decision, reloads the chat after the model finishes and produces a plan with no effects.

The five tools are small on purpose:

This makes the agent flexible without giving it a blank cheque. It can choose the tools and their order, but it cannot invent a price and pass that price into the calculator.

Why the Flow checks the chat twice

AI work takes time. A teammate may open the conversation while the model is preparing a proposal, or the customer may send a second message that changes the request.

The workflow checks for that race before the model and again afterwards. It stops when it sees any of these conditions:

• the chat is assigned to a person or department;
• the chat carries the wa-sales-human label;
• a newer inbound message has arrived;
• the event and configured WhatsApp number do not match;
• the message is a group, an unsupported hidden-number chat or an attachment that needs a person;
• the agent cites a business fact that does not appear in an observed tool result.

The final node always reports actionsEnabled: false, readyForEffects: false and actionsExecuted: []. There is no send-message node hidden elsewhere in the JSON.

Configure it for your business

You need a Wassenger number, a Wassenger connection in Flows and an OpenAI connection for the included model node.

1. Open Wassenger Flows and create an empty Flow.
2. Paste the complete JSON from the final section into the canvas. Starting from an empty Flow avoids the duplicate Manual Trigger error.
3. Open Entrada Wassenger, select the Wassenger connection and choose the exact WhatsApp number used for the test.
4. If the six read nodes do not inherit the connection, select the same connection in each one.
5. Open OpenAI Chat Model and select your OpenAI credential.
6. Replace the example inside Tu negocio with real offers and policies, set example to false, and keep the IDs short and stable.
7. Leave the Flow unpublished while you review the configuration.

The Code Tools read Tu negocio during every execution. You do not need to edit JavaScript for each customer. Add or change offers and policies in that configuration node; the lookup and calculation tools use the new data automatically.

A good first test

Use a dedicated test number and a contact you control. Publish the Flow only for the test window, then send one new text message such as:

How much are two portrait sessions, and do I need to pay a deposit?

Open the execution and inspect Vista previa. Check these fields:

• proposedReply: the answer the agent would send;
• decision.sources: the business records that support the answer;
• toolTrace: the tools, bounded arguments and results observed during the run;
• blockers: the reasons the proposal was stopped;
• actionsExecuted: this must remain an empty array.

Do not use the trigger sample as a live test. A Flows sample can be built from an older real conversation. This template blocks those samples before they reach the model.

What has been validated

The exact Wassenger version below passed the static integration verifier. It was imported into Wassenger Flows and received a controlled inbound message. OpenAI completed five model calls; the agent used consultar_ofertas, consultar_politicas and calcular_importe; and the calculated total was 18,000 euro cents.

The post-agent validation and preview also ran successfully on that execution data. Those final nodes were continued one by one in the debugger, so this evidence does not yet claim a single uninterrupted webhook-to-preview run. No WhatsApp message was sent and no contact or chat was modified.

The template is ready for controlled evaluation. It is not a production auto-reply bot. Sending, assignment, persistent chat locking, duplicate handling and the full acceptance matrix still need a separate implementation and test cycle.
