- When a buyer selected "Save my payment details" in the checkout, the Alias is shown in Magento, but stays in "pending". It doesn't go to "active".
- In the Ingenico backoffice, no Alias is saved.
The Alias field in the database is set to 32 characters. However, the value from Ingenico can be longer than that. This results in an error when the Order Request tries to find the Alias. As a result, the parameter ALIASPERSISTEDAFTERUSE = N will be sent to Ingenico, which will erase the Alias at Ingenico.
Change the Alias column in the table ops_alias from varchar(32) to varchar(255). The appropriate SQL query is
ALTER TABLE ops_alias MODIFY alias VARCHAR(255);
This problem affects versions up to 16.12.14. It has been fixed in later versions.
