3. Integration with e-Commerce

3.1 Payment method selection

Once you have activated at least one of the Limonetik payment methods in your PostFinance account, you can offer these payment methods to your customers in a selection on the payment page.

However, if you have chosen to offer the payment methods in a selection screen on your own site, allowing the customer to be redirected directly to the correct payment method, you need to make use of the PM and BRAND parameters.

The following table shows the values you can submit with the PM and/or BRAND parameter:

4. Transaction processing

4.1 Authorisation and payment

Note for FacilyPay, Multibanco and YesByCash: The authorisation may take a few days. Until the final status is known, the transaction remains in the uncertain status 51. After that, depending on the outcome, the status will automatically be updated to 5 (Authorised) or 2 (Refused). If, however, you've chosen Direct sale as default operation code, a capture will follow after the status has changed from 51 to 5.

4.2 Transaction maintenance

You can perform partial and full refunds on Limonetik transactions.

Maintenance operations, such as refunds, can be performed directly in your PostFinance account, via a DirectLink request and through a Batch file upload.

Limonetik asks that merchants proactively use cancellation instead of expiration of authorisation, because for some payment methods the authorised amount is in fact taken from the card and then refunded at cancellation/expiration.

4.3 Slimpay processing

4.3.1 Sign mandate

In order to let a customer sign a mandate and to process the signature, a dummy transaction has to be executed with an amount of €0.01. This amount will not be debited from the customer’s account nor will it be credited to your merchant account. This amount has to be transferred from your merchant account to PostFinance and will also be used as placeholder to Limonetik.

In order to hide this amount for the customer on the payment selection page of PostFinance, you need to perform a direct call to the payment method.

In practical terms, this means that the PM and BRAND values for SlimPay need to be sent along with the other data to the PostFinance platform (see Payment method selection). This allows the platform to redirect the customer directly to SlimPay without showing the amount of €0.01 amount.

Limonetik Slimpay flow

PM = Payment Method
Payment Service Provider = PostFinance

4.3.2 Recurring transactions

Currently it is not yet possible to sign the mandate via our PostFinance platform. The mandate has to be signed directly via the SlimPay back office.

Recurring transactions with the mandate have to be processed directly via SlimPay:

  • by sending a batch file to SlimPay
  • manually in the SlimPay back office

For more information on this procedure, please contact SlimPay directly (www.slimpay.net).

FAQs

The time to activate a payment method depends on the following factors:

  • It generally takes the acquirer or bank about a week to complete your affiliation. If you already have an affiliation, the activation takes a few days.
  • Some payment methods require additional checks before they can be activated, e.g. in case of 3-D Secure, which is requested directly at VISA or MasterCard (and not at the acquirer). 

With PostFinance Collect, you can activate several payment methods in one go.
