1.Introduction
This is the manual for the integration between Prestashop and Lundify.
This integration ensures that orders from Prestashop webshop are automatically processed to invoices in Lundify. Because the orders go directly into the online retailer's accounting system, this saves time on financial administration.
Please pay special attention to the following
- This integration is a financial integration. It is not a logistics integration. It is not suitable for updating customers in Lundify, printing packing slips, or synchronizing products/inventory.
- This integration does not replace the work of an accountant. It saves time because you no longer have to retype documents. The accountant is still needed for advice, expertise, and control.
- Please note: Bjorn Lunden Lundify does not support OSS. This integration is therefore not suitable for OSS. If your webshop falls under OSS regulations, the advice is not to use this integration, or only for non-OSS sales.
Tip: Other customers using this integration found the tips in the FAQ for Prestashop and in the FAQ for Lundify.
Install integration
Installing the integration starts with signing up for a trial period, via our integrations page. After registration, you will receive an email containing an installation URL and login details. With this installation URL, you start the installation of the integration.
The installation is complete when both connection dots are green, and the settings in the Configuration tab have been entered and saved.
There is a trial period of 30 days.
If you want to install another integration, you can do so in the same way. Make sure you are logged out of the integration dashboard and preferably start the new installation in an incognito browser.

2.How the integration works
A order from the Prestashop webshop is processed to a Lundify invoice.
New orders from your webshop are retrieved at least once per hour. If they have the correct status, they are processed to Lundify. You can set the statuses via the dashboard, tab Configuration.

Pre-check orders
At the start of processing an order, we perform a number of checks on the Prestashop order:
At the start of processing an order, we perform a number of checks on the Prestashop order:
- It is checked whether the total of the Prestashop order is equal to the sum of the amounts in the order lines plus the shipping cost amount.
- If the order is an ICP order, the VAT number is checked.
- It is checked whether a corresponding VAT code exists in Lundify for the VAT in each line.
- It is checked whether the order has not already been processed.
Processing orders
Processing a Prestashop order to Lundify takes place in three steps:
Processing a Prestashop order to Lundify takes place in three steps:
- It is checked if the customer already exists in Lundify. If not, the customer is created. Matching is based on the email address.
- When processing to Lundify orders, it is checked whether the products from the Prestashop order are already present in Lundify. Missing products are created.
- The Lundify invoice is created and added.
3.Required: Prestashop API key
To create the API key in your PrestaShop webshop, go to Advanced parameters - Web services via the menu.
Read more Required Prestashop ....
Read less Required Prestashop ....
Click on Add New to create a new API key.
If you click Generate on the next screen, an API key will be automatically generated. You can also create an API key yourself, but it is safer to let the system do it. Also provide a description so that you know later what you are using the API key for.
Finally, you need to set the permissions for the API key. The integration only wants to read from the PrestaShop webshop. So, only select View permissions for the following items:
addresses
categories
countries
customers
order details
orders
order state
producten
statussen
taxes
4.Required: Lundify connection
A public key is required to connect to Lundify. You can find this key in your Lundify dashboard. Log in and go to Integrations. If you click on the right gear icon (2), a popup will appear. Activate the integration (3) and copy the key (the string in the box).
Then you log in on the dashboard https://uwkoppeling.webwinkelfacturen.nl. Enter the key in the Configuration, Authentication, or All Settings tab. This establishes the connection with Lundify.
5.Installation
After the installation, check using this FAQ, whether the integration works.
Installing the integration starts with signing up for a trial period, via our integrations page. After registering, you'll receive an email with an installation URL and login details. Use this installation URL to start the integration installation.
Activating the integration consists of three steps:
1. Establishing the connection with the Prestashop webshop. Through this step, you authorize the integration to read the data from your webshop.
2. Establishing the connection with Lundify. This authorizes the integration to write transactions to your Lundify administration and read information.
3. Configuring additional data, such as the VAT settings.
Read more Installation ....Read less Installation ....
Before the integration can be used, the terms and conditions must first be accepted. The terms and conditions are based on the general ICT Terms and Conditions (industry organization) and the general GDPR guidelines. We also need a name, email address, and the country of the webshop. 
Authentication PrestaShop webshop:
Authentication with your PrestaShop webshop is done via the API key you created in a previous section. Click the red Connect button next to PrestaShop and enter the API key in the popup window. If the connection is correctly established, the indicator will turn green. If the connection is not established, check that the web service is enabled in the PrestaShop webshop.

Authentication Lundify
Establishing the connection with Lundify is done via the red Connect button in the Configuration tab. In the pop-up, you enter your Customer Code (this is the Lundify online 5-digit member number), and the token you created in the previous section. Please note, you need the entire code as a token, including the 1-part.
Settings Lundify
To use Lundify, select an administration within your account. You also indicate in which journal the revenue should be posted and what the debtors account is. The journal for processing (individual) orders will be a Sales journal.

Configure VAT rates and general ledger accounts
When configuring the VAT rates and general ledger accounts, a link is created between the VAT rates in webshop and the VAT codes and revenue accounts in Lundify. You can always make changes by clicking the blue 'Edit' button and selecting an option from the drop-down menus.
By default, all EU countries are shown in the list. You only need to configure the countries you sell to, and - if applicable - ICP and International.
The integration shows the standard VAT rates for Europe. You can adjust the VAT percentage with which you sell - left column. For example: By default, sales to Germany are set to 21%, but if you sell in the webshop with 19%, you can adjust that in the left column. Intra-Community (ICP) and international deliveries
The Intra-Community supplies / ICP option is intended for business-to-business deliveries within the EU. These sales are invoiced with 0% VAT. A VAT number from the customer is required. The International option applies to deliveries outside the EU. For these sales, the integration expects 0% VAT; otherwise, the sales cannot be processed. Separate VAT codes and general ledger accounts can be configured for both ICP and international deliveries.
Once the VAT settings have been configured and saved, you will always see the selected VAT rates. If you want to start over, you can use the grey 'Remove VAT settings' button. Your current settings will then be deleted and you can begin again.

Configure payment methods
You can create a link here between the payment methods in the webshop and a fixed debtor in your Lundify administration. Orders with a payment method from the list will then always be posted to this debtor. In that case, no new debtors will be created.
Note: It is not possible to set fixed debtors for ICP orders. For an ICP order, a valid VAT number must be transmitted. Therefore, a debtor will always be created in Lundify for an ICP order.

6.Day-to-day: From PrestaShop
In this section, we show how we retrieve the orders from the webshop.
Processing schedule: New orders from your webshop are retrieved and processed to Lundify at least once per hour. In addition, every night the orders that were previously retrieved and not yet forwarded to your accounting system are reviewed. The order status of these orders is checked to determine if they should now be processed.
Once an order has been processed, it cannot be processed again. Any order changed in the webshop after it has been processed will not be updated in Lundify.
Please note: Due to the load on our systems, we go back a maximum of 3 months in time to check the status of orders and process them anyway. In addition, the number of orders that can be checked is limited to 300. Therefore, ensure that orders are completed in a timely manner so that the integration can process them and you do not have to manually re-enter them.

Order and invoice numbers: It is possible to provide the Prestashop order or invoice number to the Lundify invoices. When processing the invoice number, we only process the number and not the fixed prefix that is sometimes set in Prestashop. Sometimes it is desirable for reconciliation to process the checkout ID or cart ID of the Prestashop, but unfortunately, we cannot read those via the PrestaShop API. Here is an explanation of how other Prestashop webshop owners have solved this: Cart ID Prestashop.
VAT numbers For business orders within the EU, outside the Netherlands, a VAT number is mandatory. The integration checks for this and also verifies the validity of the VAT number.
VAT calculation: Prestashop webshops sometimes have VAT rates for all countries with characters from the respective country in the name. For example for Cyprus or Greece. In that case, the integration cannot store the VAT rates. We advise adjusting the names of the VAT rates in the webshop. An explanation can be found here: VAT rates Prestashop.
