Google Pay CRYPTOGRAM_3DS integration for websites

Question

I am trying to integrate Google Pay into one of our websites. If I provide only CRYPTOGRAM_3DS as an authentication option, the Google Pay button is not getting displayed in Desktop Chrome and even in Android Chrome also. I have read that CRYPTOGRAM_3DS is used for the cards that got stored in Android device as tokens. Does that mean that I have to use CRYPTOGRAM_3DS only for Android app integration or will it work for web integration also? I really want to understand when we have to use CRYPTOGRAM_3DS as an authentication method for Google Pay integration. If it supports for web integration, what are the things that I need to do to really see the Google Pay button with only CRYPTOGRAM_3DS as authentication option?

Answer 1

I have read that CRYPTOGRAM_3DS is used for the cards that got stored in android device as tokens.

This is correct, CRYPTOGRAM_3DS is only available for cards tokenized using Google Pay. This means that it is only available on Android for both web and Android integrations on an Android device.

Can you include a sample integration with sample code?
