1.Introduction
This is the manual for the integration between Prestashop and Yuki.
This integration ensures that orders from Prestashop webshop are automatically processed to invoices in Yuki. 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 Yuki, 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.
Tip: Other customers using this integration found the tips in the FAQ for Prestashop and in the FAQ for Yuki.
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 Yuki as a Yuki invoice. The draft invoice option is default and is used most frequently. The processed invoice option can be requested from us. For both options, you need the paid sales module in Yuki.
New orders from your webshop are retrieved at least once per hour. If they have the correct status, they are processed to Yuki. 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 Yuki for the VAT in each line.
- It is checked whether the order has not already been processed.
Processing orders
If the check is successful, the order will be processed to Yuki. The debtor details are placed in the Yuki invoice. Yuki itself processes the debtor details.
If the check is successful, the order will be processed to Yuki. The debtor details are placed in the Yuki invoice. Yuki itself processes the debtor details.
Post-check
After the order has been forwarded and a success message from Yuki has been received, the order is marked as handled. The Prestashop order appears at the Reporting tab on the dashboard.
If Yuki returns an error while processing the order, the order appears in the Errors tab on the dashboard. Via the yellow button More info more information about the problem can be found. Via the red button Report problem can the order with all necessary information easily be submitted to us after you have tried to resolve the problem yourself. If the problem is solved, in some cases the orders can be processed again with the blue Process button.
Data
Information about the data that is processed can be found in the section Day-to-day: To Yuki later in the manual.

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: Yuki codes
The Yuki website explains how to generate an access code for the integration for your Yuki administration code as a user with a direct role. The access code is the 'webservices API key' generated in Yuki.

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 Yuki. This authorizes the integration to write transactions to your Yuki 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.

Connection Yuki
You establish the connection with Yuki using the administration ID and API key determined in the previous step. Click the red Connect button next to Yuki. You can then enter the administration ID and API key in the pop-up window.
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 Yuki. 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
Here you can create a link between the payment methods in webshop and a clearing account and fixed debtor in your Yuki administration. Orders with a payment method from the list will then always be booked under this debtor and to the clearing account. 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 Yuki 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 Yuki 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 Yuki.
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 Yuki 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.

7.Day-to-day: To Yuki
Create transactions
A order from the Prestashop webshop is processed to Yuki as a Yuki invoice. The draft invoice option is default and is used most frequently. The processed invoice option can be requested from us. For both options, you need the paid sales module in Yuki.
By default, the integration places the unit price and quantity in the Yuki invoice lines. Yuki will calculate the line totals itself. This may result in rounding differences. If these rounding differences are unacceptable, the integration can, via a special contract setting, also include the line totals. In that case, the line totals are leading in Yuki.
This method is not standard because Yuki generally discourages it and only makes exceptions for specific situations.
Create debtor
When processing customer information, the data is included in the sales transaction and Yuki will handle further processing. The invoice address is included, even if the shipping address is different.
