FASTA Customer Support on WhatsApp
Today, details are collected in WhatsApp one message at a time. In this demo, the bot sends fewer, fuller messages, and when several details are needed it sends a link instead. The customer fills in a short FASTA form, with the details you already have filled in for them, and the confirmation comes back in the same WhatsApp chat.

How it works
Landbot checks the number against your registry API and answers with one welcome and the menu.
The bot sends a link to a Landbot web bot styled as a FASTA form. The link carries a reference for this customer, so the form loads their name, account and balance from your API.
When the customer submits, the web bot sends the answers to your API and the arrangement is recorded in your system.
The web bot hands the result to the WhatsApp bot through Landbot's API, so the WhatsApp bot replies in the same chat with the result and the next buttons, within WhatsApp's 24-hour reply window.

Before the customer can choose anything, the bot sends the welcome, "We're running a security check…", "You're all set!" and "We're checking to see if you have an open loan account…".
Change: run the checks silently and send one welcome that already carries the menu. About 33,000 fewer messages in the period.
After an answer the bot asks "Is there anything else we can assist you with?" as a separate message, and going back to the menu sends the menu again. Some customers go round this loop several times.
Change: send the answer and the next options together in one list message.
"Questions about payment" goes to an agent, who collects the details one message at a time. Outside 08h00–17h00 the customer is told to come back and your team gets a Slack alert.
Change: the payment arrangement form, available 24/7. Try it in the demo above with "Customer writes after 17h00".
