Configuring the payment method

Log in to LiqPay → For business → add a shop that will accept payments. Open the API tab and make sure the following options are enabled: 

  • order_id;
  • Signature

Do not fill out the fields Server-server notification URL and Client-server shop URL. These data will be transmitted to BILLmanager while making a payment.  

Trusted IP — enter BILLmanager IP address if you want to restrict access to API by IP. 

Public key and Private key are required for payment method configuration in the billing system.

Navigate to Provider Payment method and complete the following fields:

  • Step 1 Select a payment method — choose "LiqPay".

Additional information

The module is installed from the latest available version of the product and requires an update of the BILLmanager platform, because the module version cannot be higher than the platform version.


To allow for refunds navigate to Provider → Payment methods → Edit → check the Allow refund box. Refund can be made only for "Paid" payments.
