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 e-mail notification containing the form that the gateway was unable to process and the value of the invalid field.
The 132 - signature_wallet_two_steps error appears only if there is a signature problem during a transaction in two-step via a wallet. Example: Masterpass in 2 steps.
The signature computation problem occurred while sending your second payment form.
We invite you to check the following causes.
|The MODE (TEST or PRODUCTION) or the key is incorrect.|
You can use the gateway in TEST or PRODUCTION mode.
Each mode has its key. Make sure that you use the correct key according to the desired mode.
Check your key in the Settings > Shop menu > Keys tab of your Expert Back Office.
|The signature is not transmitted or the transmitted one does not match with the signature computation rule.|
Check that the signature field is present in your form.
Check that the signature field is spelled correctly (all lowercase).
Make sure the field value is not empty.
When computing, the values of the following parameters are required in this order: vads_amount + vads_ctx_mode + vads_currency + vads_payment_option_code + vads_site_id
Check that you have not forgotten a parameter or added an optional parameter.
Make sure the fields were sorted correctly.
