We have received email from visa - upgraded 6.3 visa checkout API by August 31 2018. We would like know any one have implementated v6.3 and what is advantages? what is eol for 4.6.2 Visa Checkout SDK?
That's a good question. I'll take a look and reach out to you soon.
Unfortunately, the EOL for VCO API version 4.6.2 is not available at this time. All of our newest API versions are going to have increased security enhancements, support fixes, and other enhancements, (for example, version 6.3 features an updated stay signed in opt-in screen to make it easier for customers to adopt this feature), so you are going to want to make sure you are updated with each new release.
