I'm using Omnipay with CodeIgniter to allow customers to checkout on Paypal. I was using test mode during the development on the website, but now the site is done and ready to be put in production.
But I don't know how to setup Omnipay to use live payments and not Sandbox mode. I tried setting the testMode to false. -> Security header invalid.
I tried creating REST Api credentials -> You can't make this api call.
I know that's probably not the right way to do this, but at least I explored options.
So please, what's the most suitable configuration to do live Payments on PaypalExpress with Omnipay ?
Thanks in advance.
