In PRODUCTION mode, if your buyer gets an error message such as:
|An error occurred during the payment request, please make sure that the posted parameters match the ones specified in the documentation.|
It becomes impossible to make the payment and the transaction is definitively lost.
You will receive an email notification containing the form that the gateway was unable to process and the value of the invalid field.
We invite you to check the following reason to resolve the issue:
|Your payment is an installment payment, but your offer does not authorize it.|
You have requested the creation of an installment payment, but your offer does not allow it.
The activation of the payment in installments feature is subject to the prior agreement of Natixis Payment Solutions. Please get in touch with your customer advisor.
