You do not need to start by choosing an API or learning a protocol. Start with a customer question your business can answer and the next useful step. Your role is to define the outcome, supply reliable information and judge whether the result is correct.
Choose one customer task
Write a sentence a real customer might say: “Which size fits this device?” or “Can I book this service for these dates?” Then write the evidence that would satisfy the request. A suitable product or a confirmed request is more concrete than “a better AI presence”.
Keep the first version focused. A small journey with clear sources is easier to evaluate than a broad promise to answer every question about the business.
Prepare a brief for the person building it
Include the customer, the question, the approved pages or systems, any missing details and the intended next step. Name the person who owns the answer and the person who handles a failed request.
Add one example of a request that should be declined or handed to a person. If a customer asks for a delivery guarantee you cannot make, the assistant should explain that limit rather than invent a date.
Ask the supplier to explain the work in plain language
- Which information can you use directly from our website?
- Which data needs a live connection?
- Which actions need the customer to sign in or confirm?
- What will the customer see when the task cannot finish?
- What do we maintain, and what do you maintain?
- What is included in the quoted scope?
A no-code interface can simplify configuration. It does not remove these decisions. Use the tool evaluation checklist before selecting a platform.
Review a working example before launch
Try the ordinary question, an incomplete question, a missing-source case and an unauthorised request. Ask to inspect the business result, not only the conversation. If a checkout opens, verify the chosen item; if a purchase is claimed, verify the order.
Keep a simple record: request, expected answer, observed result and next fix. The evaluation toolkit can help structure this review.
Keep access and publication explicit
Ask when you can test, what must happen before customers use the experience, and who owns any platform submission. No supplier can establish public approval merely by creating a prototype.
