Introduction
This plugin integrates VAI Pay as a payment method in your JTL store.
VAI Trade GmbH offers an invoice purchase solution in the B2B sector, which allows merchants to purchase goods from their suppliers by invoice and pay in instalments. VAI Trade acts as a customer towards the supplier who buys on account and resells the purchased goods to the retailer accordingly. The supplier receives a payment for his goods within 24 hours and thus bears no risk.

You can also find a direct link on the help page of the plugin. Select VAI Pay via the pencil icon and configure the payment method as needed.
In addition to the standard settings for payment methods, the plugin contains the settings for the payment method under the Settings tab. Here you can store the data necessary for operation, which you have received from VAI Pay for the setup.
If the VAI Pay payment method is selected, the pay button is replaced with a payment button in the VAI design. You can choose from three different button texts.
You specify where and with which method the button is embedded via the selector and selector method.

JTL-Wawi
In order for the payments made via VAI Pay to be assigned to the orders in JTL-Wawi, extended settings must be made for this. For a correct function with VAI Pay, the described JTL workflows are of particular importance, more information on this can be found here: https://support.vaitrade.de/de-form/articles/3482535-welche-informationen-mussen-auf-meiner-rechnung-vorhanden-sein.
Set up payment method
In JTL WAWI, open the payment method management Zahlungen → Zahlungsarten.
Create "Vai Pay" as the payment method. Note that the payment methods must correspond to the "Displayed name" in the JTL store.
Set up the order attribute
Change to Verkauf (F6) und open an order. You can edit the order attributes with
Create the Attribute “VaiDealNumber“. Now the transmitted dealNumber is displayed:
Customise invoice template
For the additionally required invoice information (delivery address, VAI Pay VAT ID, etc.), the following block must be set in "Rechnungsdruck nach Zahlungseingang":
Lieferadresse: {{ Vorgang.Lieferadresse.Firma }} {{ Vorgang.Lieferadresse.Firmenzusatz }} {{ Vorgang.Lieferadresse.Straße }} {{ Vorgang.Lieferadresse.PLZ }} {{ Vorgang.Lieferadresse.Ort }} {{ Vorgang.Lieferadresse.Land.NameDeutsch }} Lieferbedingung: gemäß Incoterms 2010:CIP Umsatzsteuer ID (VAI Trade GmbH): DE311841845
Terms of delivery should only be listed if applicable.
Skonto is not taken into account by the plugin.
Set up JTL-Workflow
VAI Trade GmbH acts as the buyer to the seller, so unlike other orders, the invoice may not be addressed to the buyer, but must be addressed to VAI Trade instead. Set up a WAWI workflow to automatically change the invoice address of the order to the invoice address of VAI Trade to be defined when an order is created with VAI Pay as the payment type. To do this, proceed as follows:
Set up "Vai Pay" as a payment method.
Open Admin >JTL-Workflows:
Choose Aufträge:
and mark up “Komplett bezahlt”
Create a new Workflow:
Define conditions:
Define for the previously created payment type "Vai Pay" that payments should be processed.
Set up actions:
In Table Address data all variables are listed which have to be changed.
Choose action “Werte setzen“
Specify with "Variable" which value should be changed for
Auftrag > Zahlungen > Rechnungsadresse > VariableSpecify the new value for Wert.
Option “Feld leeren” is not available, to empty a variable please insert a "-" (minus) as a workaround.

Test WAWI-Workflow
Now test the Wawi workflow on a test order by first creating a test order in your store (cash payment or similar) and transferring it to the WAWI. Set the payment for the order via "Vai Pay" and a payment receipt. Make a note of the order number (e.g. 123).
Go to JTL-Workflows by choosing Aufträge > Komplett bezahlt > “Auftrag_Komplett bezahlt”
Your workflow actions should look something like this:
Start the test
Select an object by searching for order number (e.g. 123)
Open the order again. The invoice recipient has been changed:
Set up E-Mail template
As a seller, you have to send the buyer's invoice to the intermediary. In this case, a differentiation based on payment type must be set up in the e-mail template. The correct e-mail address for the transaction has already been set by the workflow. The corresponding DealNumber has been assigned in the incoming payment for the transaction. Open Admin → “Druck- / E-Mail- / Exportvorlagen“
Adapt subject
If you have not made any changes to your standard e-mail template, you can use the code as it is. Otherwise, adapt the code or insert your modifications in the ELSE part:
{% if Vorgang.Zahlungen.ErstesObjekt.Zahlungsart.Name == "Vai Pay" %} Rechnung zu VAI-Deal: #{{ Vorgang.Zahlungen.ErstesObjekt.ExterneTransaktionsID }} {% else %} Rechnung über "{{ Report.InvoicePosition[0].Name | Truncate: 20 }}"{% case Report.InvoicePosition.Size %}{% when 0%}{% when 1 %}{% when 2 %} und einem weiteren Artikel{% else %} und {{ Report.InvoicePosition.Size | Minus: 1 }} weiteren Artikeln{% endcase%} von {{ Report.Company.CompanyName }} {% endif %}
Customise Invoice PDF Name
The same applies to the naming of the PDF invoice name. Insert your modifications in the ELSE part at the end of the code line:
{% if Vorgang.Zahlungen.ErstesObjekt.Zahlungsart.Name == "Vai Pay" %}#{{ Vorgang.Zahlungen.ErstesObjekt.ExterneTransaktionsID }}.pdf{% else %}Rechnung-{{ Vorgang.Rechnungsnummer }}.pdf{% endif %}
On operation
Shop
The payment method is integrated in the storefront of the store like a regular JTL store payment method.
Frontend
he VAI Pay payment method is only available to buyers under certain conditions. The payment method can only be offered for B2B in Germany and only in Euro.
If the billing country is not Germany, VAI Pay will not be offered as a payment method.
If a currency other than Euro is selected in the store, then VAI Pay cannot be offered as a payment method.
If the buyer has not entered a company in the customer details, VAI Pay will not be offered as a payment method.
Backend
In the plugin backend you can view the orders that were paid with VAI Pay. The search helps you to find the desired orders.
Column | Description |
---|---|
Order ID | JTL-Shop order Id |
Customer | Name of the customer |
Invoice ID | Internal invoice number (UUID generated by the plugin) |
Deal-Number | VAI Pay deal number (internal ID generated by VAI Pay) |
Status | Status of the payment (confirmed/unconfirmed). The status is confirmed when the order has been created in the JTL store and VAI Pay has confirmed the transferred amounts. |
Total Sum | Total gross amount in the JTL store (due to any fees, the amounts in the VAI customer account may differ). |
Order date | Timestamp of the order or payment |
IP-Address | IP of the buyer/customer |
WAWI
The JTL workflows, once set up, start automatically during the Wawi reconciliation and do not require any further processing during operation.
Customization
The payment method itself has no customizable elements. However, you can specify which color scheme and button text to display on the summary page.
If you are using your own template, enter your special selector for the "Order Paid" button under Button Selector (Show).
Troubleshooting
If you observe any problems with the plugin, first check the logs and if necessary contact our support or your service partner if you cannot solve the problem on your own.
The more information you can give to the support in case of a problem, the sooner we will be able to help you. Non-reproducible problems, on the other hand, are also difficult to analyze.
Messages
This currency is not supported!
This message is displayed when the buyer has changed the currency other than Euro on the summary page and wants to complete the order. He will be redirected back to the shipping and payment method page and can select a payment method suitable for the desired currency.
The payment was canceled
This message is displayed when the customer clicks on "Cancel" in the VAI Pay account and thus cancels without submitting the order.
The submitted data is invalid. The order could not be created!
This message is displayed if the data transmitted by VAI Pay could not be decoded with the secret key.
The internal ID is invalid. The order could not be created!
This message is displayed when the data transmitted by VAI Pay does not match the current data in the session.
VAI could not confirm the payment!
This message is displayed when an error occurred in the API communication. In this case, VAI could not finally confirm the authenticity of the transmitted data. However, the order could be successfully created in the JTL store. The buyer was redirected to the order confirmation page.
Check logs
In the plug-in backend, success and error messages are displayed to the merchant for each action. The plug-in logs all actions into the shop log (debug level). All corresponding messages can be conveniently filtered with the prefix "VAIPAY>".
To find out where a problem lies, the logs help you and us. Depending on the error pattern, one of the following 3 logs is more or less relevant.
Browser log
The browser log is usually relevant when something in the shop's frontend behaves strangely or does not react. (Example: You click a button and apparently nothing happens).
You can see the browser log by pressing F12 in the browser and then switching to Console.
Shop log
The shop log is always interesting if unexpected error messages are displayed in the frontend or if the plug-in reacts to inputs in the frontend but does not deliver the expected result. Sometimes the browser log also shows that the information is more likely to be found in the shop log.
You can find the shop log in the JTL admin area under Administration → Troubleshooting → Log.
The JTL log works with log levels in order not to fill the database with log data indefinitely. Conversely, this means that you will only see log messages if they have been generated after the log level has been changed. The plug-in logs almost exclusively in the debug log level, except for critical errors. So if something does not work, you should first activate the debug log level, then perform a test order, then deactivate the debug log level again and consult the messages logged in the meantime.
Webserver-Log
The web server log becomes relevant if you encounter an error 500 (= white page) somewhere.
Your hoster can provide you with the web server log.
In the standard configuration, the JTL shop does not log anything in the web server log, not even critical errors such as an error 500.
In order for the shop to log these errors, the individual *_LOG_LEVEL values must be changed from 0 to E_ERROR in /includes/config.JTL-Shop.ini.php.
Attention: Only edit the shop's config file if you know what you are doing! Incorrect adjustments here can make your shop inaccessible or (encrypted) data unusable. If in doubt, ask your hoster or service partner for help.
