# Prestashop

## **Phase 1: Backend Configuration (Webservice API)**

*This step allows Kleep to retrieve your product catalog and order history to calibrate the algorithm.*

**1. Enable the Webservice**

1. Log in to your Prestashop Admin panel.
2. Go to **Advanced Parameters > Webservice**.
3. Enable the “Enable Prestashop’s webservice” setting > **Save**.

**2. Create the API Key**

1. Click on **“Add new webservice key”**.
2. Click on **“Generate”** to create a key (copy it, we will need it later).
3. **Permissions:** In the resource list, check the **View (GET)** boxes for the following resources:
   * `products`
   * `product_options`
   * `product_features`
   * `product_feature_values`
   * `product_options_values`
   * `categories`
   * `combinations`
   * `images` / `image_types`
   * `orders`
   * `order_states`
   * `stocks`
   * `stock_availables`
   * `shop_urls`
   * `shops`
4. Save.

**3. Share the Key**
Send the generated API Key to your Kleep contact via email.

## **Phase 2: Frontend Integration (Widget)**

*This step involves adding the Kleep script to your product pages (PDP). Compatible with all Prestashop versions.*

Follow our [**JS Library Widget guide**](/cms/js-library) to install and configure the front-end CTA on your product pages.

***

## **Phase 3: Handling Missing Data (SFTP)**

*If your Prestashop API does not allow retrieving Returns or certain specific data, we use CSV file exchange.*

Please visit the documentation below. It will guide you step by step to send us the missing data.

## **Phase 4: Validation & Go-Live**

1. **Test Environment** — first deploy on your **Preprod/Staging** environment.

2. **Visual Validation** — before going live, verify:
   * Does the button appear correctly?
   * Does clicking open the pop-up (Drawer)?
   * No “CORS” errors in the browser console?

3. **Go-Live** — once validated by you and the Kleep team, deploy the changes to your **Production** theme.---
