Usage Client Custom Fields in a Payment Gateway

[thenet88]

Hello,

 

I have an Client Custom Fields called "Drive ID" in my WHMCS script.

I'm developing a plugin payment and I want to know the "Drive ID" value for each client.

How I can know the value? I tried with $params["clientdetails"]["client_custom_field_driveid"];

But I do not recognize the variable client_custom_field_driveid

In http://docs.whmcs.com/Gateway_Module_Developer_Docs , I can not find the information.

 

Thanks you very much.

 

Best regards.
