error 135

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.

The eligible_amount_inconsistency error appears during a transaction via Conecs Electronic Meal Vouchers.

We invite you to check the following cause.

The expressed amount is greater than the transaction amount.

Make sure the value of eligibleAmount element is not greater than the transaction amount.

For CONECS, for example, the vads_acquirer_transient_data field should be valued as follows:

vads_acquirer_transient_data ={"CONECS":{"eligibleAmount":"1299"}}

For example, if the transaction amount is 12.50 euros, the eligibleAmount element must be populated at the maximum with this amount but never above.
