I'm fairly new to Braintree API. I'm using Recurring Payments. And for that I'm using Drop-In UI that is provided by Braintree. Everything goes well but it only shows two fields: Card Number and Expiration Month/Year; and the Paypal button. It's not showing CVV field.
I believe the CVV field is optional and the transaction will still go through if I were to not accept it. But I'm wondering why is it not showing up?
Braintree's new documentation is very limited. And I can't find much info on this problem their website. Any pointers will be much appreciated. Thanks.
go to Settings -> Processing -> CVV, enable CVV verification rules, and renew the client token.
In this way the CVV field will appear in the Drop-in UI.
According to Latest Braintree integration there is some change in flow to enable 'cvv' option.
'CVV' option will be enable from braintree website.
Follow this Steps to login into braintree website:
- Go to Settings
- Processing
- CVV
- Click on Edit
- Check option 'CVV not provided(l)'
- Enable option 'for any transaction'
- Processing
After this step you can see 'cvv' option in your app.
This is surely because you are using the sandbox, no? If you have the cvv activated you can see it when you move go live
