Zoon Posted May 15, 2011 Share Posted May 15, 2011 Hello people, Following the official document for creating a payment module i successfully created a payment module. It works perfectly with my gateway's demo card number - which is insensitive to CVC code. I am unsure if I am passing any CVC to the gateway at all, as there appears to be no such variable? $params['cardtype'] – the Card Type (Visa, MasterCard, etc...) $params['cardnum'] – the Card Number $params['cardexp'] – the Card’s Expiry Date (Format: MMYY) $params['cardstart'] – the Card’s Start Date (Format: MMYY) $params['cardissuenum'] – the Card’s Issue Number (Switch/Solo Cards) Is it the issuenum? Thank you. 0 Quote Link to comment Share on other sites More sharing options...
Payton Designs Posted May 16, 2011 Share Posted May 16, 2011 I've researched a few articles regarding this and although some had different interpretations my best guess is that the issue number is the CVC. Refer to this article for some information: http://www.ehow.com/facts_6060018_visa-card-issue-number_.html If you are still unsure, you can always contact your payment gateway for an answer. 0 Quote Link to comment Share on other sites More sharing options...
WHMCS Support Manager WHMCS John Posted May 17, 2011 WHMCS Support Manager Share Posted May 17, 2011 The Issue Number is used for certain card types, mainly in the UK. It is most definitely not the CVC code. 0 Quote Link to comment Share on other sites More sharing options...
Zoon Posted May 23, 2011 Author Share Posted May 23, 2011 So where IS the CVC code? It is entered on the frontend, but how does it get sent to my gateway? 0 Quote Link to comment Share on other sites More sharing options...
