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.

Plugin-Installation

The installation of the plugin is done according to JTL standard, as it is described here.

Plugin-Update

When updating to a newer version, you can start updating the plugin to the next available version under the menu item "PLUG-INS → My Purchases > Bound Licenses → VAI Pay". In the Status column, click "Update".

Configuration

Shop

The plugin will help you to set up the payment method, for this select the "Help" tab in the plugin. There you will get an overview of the configuration. At the point, check the settings you have stored for the payment and shipping methods.

Payment methods

The configuration of the payment type is done via the standard administration in the JTL store. You can find the payment types under Administration → Payment methods. 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.

Shipping methods

Assign VAI Pay to the appropriate shipping methods/countries under Administration → Shipping. The plugin also takes into account any surcharges to the payment method. You can also find a direct link to this on the plugin's help page.

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:

1. Set up "Vai Pay" as a payment method.

2. Open Admin >JTL-Workflows:

   

3. Choose Aufträge:

   

   and mark up “Komplett bezahlt”

4. Create a new Workflow:

   

5. Define conditions:

   

   Define for the previously created payment type "Vai Pay" that payments should be processed.

6. Set up actions:

   

   In Table Address data all variables are listed which have to be changed.

   1. Choose action “Werte setzen“

   2. Specify with "Variable" which value should be changed for
      Auftrag > Zahlungen > Rechnungsadresse > Variable

   3. Specify the new value for Wert.

   4. Option “Feld leeren” is not available, to empty a variable please insert a "-" (minus) as a workaround.

7. Test Workflow

8. Save the Workflow

Address data

The setup help is intended to assist you in entering all the required variables.

Test WAWI-Workflow

1. 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).

   

2. Go to JTL-Workflows by choosing Aufträge > Komplett bezahlt > “Auftrag_Komplett bezahlt”

3. Your workflow actions should look something like this:

   

4. Start the test

   

5. Select an object by searching for order number (e.g. 123)

   

6. Open the order again. The invoice recipient has been changed:

   

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.

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.

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 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.

This message is displayed when the customer clicks on "Cancel" in the VAI Pay account and thus cancels without submitting the order.

This message is displayed if the data transmitted by VAI Pay could not be decoded with the secret key.

This message is displayed when the data transmitted by VAI Pay does not match the current data in the session.

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.

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.
