error 00
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.
We invite you to check the following reason(s) to resolve the issue:
| The fields of the form have not been encoded in UTF-8. |
|---|
When computing the signature, if the fields are not sent to the gateway in UTF8 encoding, you will find special characters, such as accents, in the form. Error example [vads_capture_delay=]
[vads_site_id=51872022]
[vads_payment_config=SINGLE]
[vads_version=V2]
[vads_currency=978]
[vads_amount=1000]
[vads_cust_name=Ren�e Martin]
[vads_ctx_mode=PRODUCTION]
[vads_trans_date=20191026083000]
[vads_trans_id=982415]
[vads_payment_cards=]
[signature=ycA5Do5tNvsnKdc/eP1bj2xa19z9q3iWPy9/rpesfS0=]In this example you can see that the accents are not well encoded for the vads_cust_name field. Make sure you handle UTF-8 encoding correctly in order to avoid signature errors. Warning: We would like to remind you that the fields returned by the gateway are encoded in UTF-8. Therefore, there is no need to reapply UTF-8 encoding to the data returned by us. |
| 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. |
| Warning: Line break or carriage return submitted in the form. |
|---|
If you insert some carriage returns or line breaks within one of the posted values, they will not be taken into account. Error example If in the address field you post: 3 bellflower street 2nd floor apt 28 The value taken into account by the payment gateway will only be: 3 bellflower street Then the payment gateway will only take the 3 bellflower street value into account to compute the signature whereas your signature computation will be based on the complete address: 3 bellflower street 2nd floor apt 28. Thus, you will get a signature computation error. CONCLUSION: Before computing the signature and sending the form, you must avoid carriage returns and line breaks. |
| Warning: Quotation marks ["] submitted in the form. |
|---|
If you insert quotation marks within one of the posted values, they will not be taken into account. Example: If in the address field you post: "Bellflower" Residence The value taken into account by the payment gateway will only be: Residence Therefore, the payment gateway will only take the Residence value into account to compute the signature, whereas your signature computation will be based on the complete address: "Bellflower" Residence. Thus, you will get a signature computation error. CONCLUSION: Before computing the signature and sending the form, you must remove the quotation marks. |
| The transmitted signature does not respect the rule of signature computation. When computing the signature, the fields must be UTF-8 encoded. The same applies to your shop which must send all the parameters in UTF-8 encoding to the payment gateway. |
|---|
Check that you have not forgotten a parameter or added an optional parameter. Make sure the fields were sorted correctly. Reminder of the computation method
