# How it works: connecting WhatsApp to your software | Meta Reva > A customer writes on WhatsApp; Meta Reva verifies them, reads the answer from your software and replies. Four-step setup, built with KVKK in mind. Source: https://metareva.com/en/how-it-works/ Simple, secure, under control # The customer writes, the system answers, _you stay in control._ Meta Reva is a secure bridge between WhatsApp and the software you use. It understands the message, verifies who sent it, reads the right information from your software and replies within seconds. The journey of a message ## Four things happen _in seconds._ The customer doesn’t even notice; behind the scenes every step follows your rules. 1. 2. 3. 4. 5. Setup ## How is it set up? _In four steps._ 1. STEP 1 ### Let’s talk We find out which parts of your work you want to move to WhatsApp, and which software you use. 2. STEP 2 ### We connect to your software We set up a secure connection to your software; your data stays where it is and is not copied. 3. STEP 3 ### We decide who sees what Together we set which information your customers and staff can see. 4. STEP 4 ### We test and go live We test with real examples and take your number live, then expand step by step. Security ## Your data _stays with you._ Rules for sensitive information such as customer details, prices and accounts are agreed with you from the start. ### Phone verification Everyone sees only their own information; someone whose number is not registered cannot access customer account details. ### You control access Owner, accounting, sales and warehouse: each role sees only its own area. ### Your data stays where it is Data in your software is not copied; only the information needed is queried in real time. ### A person steps in when needed Whenever there is any doubt, the conversation passes to your team; no sensitive decisions are made automatically. ### Every action is logged Who asked what, when, and what was done: all of it can be traced. ### A KVKK-compliant approach No more data than necessary is requested or shared; retention rules are set in advance. FAQ ## Questions on your mind, _in brief._ The most common questions about setup, software and security. **Can’t find your answer?**Write to us and we will reply the same day. [Contact us](#apply) 01 Is my data copied to Meta Reva? No. Your data stays in your software; only the information needed for each question is queried live. No copy of your database is kept. 02 Can a customer see someone else’s information? No. People are recognised by their phone number and see only what they are allowed to. An unregistered number cannot reach account, price or order information. 03 Does the AI place orders or make changes on its own? No. A record is created only after the customer confirms within the conversation, and only within the rules you set. Anything outside the rules or unclear is handed to your team. 04 Can I keep using my software? Yes. Your team keeps working in it exactly as before; Meta Reva only connects the WhatsApp side. There is nothing new to learn. 05 Do you need to visit us for the setup? No. Connection, rules and testing are done remotely over screen-sharing calls, anywhere in Turkey. 06 How long does setup take? A simple flow (for example stock and price enquiries) can go live within days. Wider scope is added step by step.
