Troubleshooting

Common Issues and Solutions​

Issue: LiqPay is not displayed as a payment method on the website​

Symptoms: When placing an order on the website, LiqPay is not available among the payment methods.

Possible Causes:

  • The LiqPay provider is in the "Disabled" state
  • Credentials are not filled in (public or private key)
  • The order currency is not supported (only UAH, USD, EUR are supported)

Solution:

  1. Go to Accounting → Configuration → Payment Providers
  2. Open the LiqPay provider
  3. Make sure the provider state is "Enabled" or "Test Mode"
  4. Verify that the Public Key and Private Key fields are filled in on the Credentials tab
  5. Ensure the order currency is UAH, USD, or EUR

Issue: Authentication error during payment​

Symptoms: After being redirected to the LiqPay payment page, an error or a blank page is displayed.

Possible Causes:

  • Incorrect public or private key
  • Keys from a different environment (test keys in production mode or vice versa)

Solution:

  1. Log in to the LiqPay merchant dashboard: https://www.liqpay.ua/
  2. Go to the API section and copy the current Public key and Private key
  3. Paste the keys into the corresponding fields of the provider in Odoo
  4. Save the settings and retry the payment
Important

For test mode, use LiqPay test keys (sandbox). For production mode, use live keys. Mixing keys will cause signature errors.

Symptoms: When clicking a payment link from an invoice or sales order, an error appears or the payment page does not open.

Possible Causes:

  • The Invoice Online Payment option is not enabled in the accounting settings
  • The LiqPay provider is not activated
  • The document currency is not supported

Solution:

  1. Go to General Settings → Accounting (Invoicing)
  2. Enable the Invoice Online Payment option
  3. Make sure the LiqPay provider is in the "Enabled" or "Test Mode" state
  4. Verify that the invoice or order currency is UAH, USD, or EUR
