2. Settings
When you use the plugin for the first time, you will need to configure some settings.
In this area, you will find:
- Notifications & alerts: receive alerts whenever there are order import issues.
- Calculation of delivery charges: The delivery charges contained in your product catalogue will be those of the carrier selected here.
- Lengow Tracker: Both options allow Lengow tracker activation with the plugin.
By default, this tracker is deactivated and has to be activated to send data to Lengow.
Second option allows to select the product unique identifier which is filled in Lengow. - Shop management: These options allow you to activate the stores you want to link to Lengow for order synchronization. These data are automatically completed and activated when connecting with Lengow. You can however add catalog ids in the fields corresponding to the need.
- Debug Mode: use Debug Mode for test orders. Reminder: this setting must be ONLY and NECESSARILY enabled on your pre-production server.
- Log Files: your logs history (imported orders, error messages, ...) over the past 20 days.
- Uninstall Lengow Module: this feature will completely uninstall the plugin. Use it ONLY when you do not work with Lengow anymore. It cannot be used to re-install the plugin.
Manage your products
=> Click on "Products" tab from the main page of your Lengow plugin.
In this area, activate product selection for your different stores ;(source catalogues exported to Lengow).
You can manually change:
- the number of products exported to the Lengow platform. Consider exporting your new products!
Changes will be visible in the Lengow platform in the next products catalogue import.
- you will find here your PrestaShop active products. If you delete or add a product, this will affect the number of exported products.
- if you choose to select products to be exported, the new products to be added into your PrestaShop will not be added to the export automatically.
Click on the "Download" icon to download your products catalogue containing your selection of products.
Note: you will find here your PrestaShop active products. If you delete or add a product, this will affect the number of exported products.
Note: if you choose to select products to be exported, the new products to be added into your PrestaShop will not be added to the export automatically.
Click on the "Download" icon 
to download your products catalogue containing your selection of products.
Manage your Orders
=> Click on "Orders" > "Settings" tab.
In this section, you'll find two tabs:
- "Overview": Here you can view orders from your Lengow account.
- "Order parameters": All import parameters from Lengow orders
- Orders are only imported only once their status has become "Waiting for shipment".
- As the import of order in the Lengow plugin causes a decrement of the stock on the product ordered, no import is made at the status "canceled" and "refunded".
- Once the order is imported, it will no longer be synchronized with the plugin.
Advanced parameters
In the "Advanced parameters" section, you'll find the following different parameters:
- Order status: the Lengow module allows you to match the order statuses from the marketplaces with the statuses made available by PrestaShop via a status matching.
- Management of the carriers for the marketplaces: When you add a marketplace on Lengow, you need to make the matching here between your PrestaShop carrier and the carriers of the marketplace in each country. Make the matching between:
- The proposed list (based on the carriers offered by your marketplaces and a default carrier).
- The drop-down menu which is based on the carriers configured in your PrestaShop back office.
- for default country you defined in your Prestashop: within an hour after connecting the marketplace
- Order import: choose here:
- the maximum period (in days) over which the plugin synchronise orders.
In the case of cron synchronisation, the time interval is automatically managed by the plugin and is based on the date of the last successful synchronisation.
For example, if the last synchronisation was an hour ago, the plugin will only recover the last hours.
On the other hand, if the last synchronisation is 3 days old, the plugin will synchronise over the last 3 days without ever exceeding the maximum number of days you have entered (It is recommended to leave this parameter with 3 days). - if you want to import orders dispatched by the marketplaces, and where appropriate, if you want to reduce the stock of products in your PrestaShop for orders dispatched by the marketplaces.
- Activate the currency conversion for orders
All orders imported into Prestashop will be automatically converted into the currency chosen in Lengow.
3. Orders management 1/2
Marketplace orders (status change) can be managed from the "Orders" tab (menu on the left).
For each of your orders from Lengow, you will find a new Lengow block with all the order information and the following actions:
- Re-import the order: recreate a new order and pass the current order through a Lengow technical error, but it's not worth further reducing stock.
- Resend the action: This allows you to resend the action to change the status of the order to Lengow. (Ideal for correcting an order import error, for example if you have just entered the tracking coli which had been forgotten).
- Re-synchronise the order: This allows you to remake the matching between Prestashop's order ID and the order ID in Lengow.
Orders management 2/2
In the plugin, you will find marketplace orders. You can see:
- if the order has been correctly imported in PrestaShop
- your orders current status (in progress and closed)
If an order is not correctly imported in PrestaShop, it will appear as "Not imported". Mouse over this message to know what is preventing import. Correct the bug and click on "Not imported" to re-import the order.
If you change an order status into "Shipped" in PrestaShop, while an error prevents the marketplace from switching the status into "Shipped" (e.g. because tracking number is missing), a "Not shipped" message will appear. Correct the bug and click on "Not shipped" to re-import the order.
If you encounter troubles whilst solving problems, contact our Support Team.
If you add a new marketplace into Lengow, consider making the new matching between your PrestaShop's carriers and the carriers of this marketplace.
