Hi,
I would like to add custom client details to both where the client can edit them, and also use them in my custom payment gateway.
For example: I have a credit card company that requires the Social Security Number of the person who's paying. Therefore, I have to add a client custom field for the client, and then use it when he pays (either by taking it from his client details, or by letting him enter the field).
After having this, I need to have access to this field from the payment gateway's "capture" function.
Help anybody?
Does anyone have examples of this?
Thanks alot
