Set Up User Context on PrestaShop

What You're Setting

User Context is a client-side JavaScript object. On every page where the widget loads for a logged-in user, you attach an object to window.Asyntai.userContext describing who they are. The widget sends this with each message, so the AI can reply with their name, order status, plan tier, or anything else relevant.

Keys act as labels the AI sees, so make them descriptive — use "Customer name" or "Loyalty points", not just "name" or "points".

window.Asyntai = window.Asyntai || {};
window.Asyntai.userContext = {
  "Customer name": "Sarah Chen",
  "Email": "sarah@example.com",
  "Subscription plan": "Pro",
  "Loyalty points": 1840,
  "Last order": "#8847, out for delivery"
};

Two ways to set it

Either assign synchronously (if data is already on the page), or provide a fetcher that runs when the chat opens. The second option is better for performance — user data is only loaded when someone actually opens the chat.

// Option A — synchronous (data already available)
window.Asyntai.userContext = { "Customer name": "Sarah", ... };

// Option B — async fetch on chat open (better performance)
window.Asyntai.fetchUserContext = function() {
  return fetch('/api/chat-context/')
    .then(r => r.json())
    .then(data => { window.Asyntai.userContext = data; });
};

How PrestaShop Exposes the Customer

PrestaShop 1.7+ themes expose a global prestashop JavaScript object that includes prestashop.customer with the logged-in shopper's data: firstname, lastname, email, id. It's available automatically on every front-office page.

Option 1 — Smarty Template Override

Add a small JS block to your theme's global footer. The cleanest location is layouts/layout-both-columns.tpl (or override layout-footer.tpl) — but the easiest is to use the Custom Code feature in admin.

<script>
(function() {
  if (!window.prestashop || !prestashop.customer || !prestashop.customer.is_logged) return;

  var c = prestashop.customer;
  window.Asyntai = window.Asyntai || {};
  window.Asyntai.userContext = {
    "Customer name": c.firstname + ' ' + c.lastname,
    "Email":         c.email,
    "Customer ID":   c.id,
    "Group":         c.id_default_group
  };
})();
</script>

Option 2 — Order History via Webservice

To include order history and totals, combine the customer ID from prestashop.customer with a proxy call to PrestaShop's Webservice:

<script>
window.Asyntai = window.Asyntai || {};
window.Asyntai.fetchUserContext = function() {
  if (!window.prestashop || !prestashop.customer.is_logged) return Promise.resolve();
  return fetch('/your-proxy/user-context?customer_id=' + prestashop.customer.id, {
    credentials: 'include'
  })
  .then(r => r.json())
  .then(data => { window.Asyntai.userContext = data; });
};
</script>

Your proxy then calls PrestaShop's Webservice (enabled under Advanced Parameters → Webservice) with an API key, reads orders/customer details, and returns the flat JSON.
