Google Pay™ Authentication Types
- PAN_ONLY (non-tokenized) - cards stored in payer`s Google account. These cards available on any device of the payer.The token contains the number and expiration date of the physical card. That is why 3-D Secure authentication is required for these cards. 3DS is required for PAN_ONLY cards. It can be indicated by the Success==3DS in Google payment response. 3-D Secure authentication does not differ from the standard 3-D Secure.
- CRYPTOGRAM_3DS (tokenized) - cards that are stored tokenized on the payer’s device. Tokenized cards are only available on the device where the card was added to the Google Pay™ app.The token contains the number and expiration date of the virtual card as well as the 3-D Secure cryptogram. Customer 3-D Secure verification for tokenized cards is not required.

Google Pay™ Web Flow
Below we can see Google Pay™ Purchase Flow and Integration steps:
Capture Flow
Capture is a transaction followed after preauth which deducts the locked amount from Payer’s card. It is important to know that the block remains for a definite period of time depending on whether this is a debit or a credit card (usually the maximum block period is 7 days for debit cards and 28 days for credit cards).
Cancel Flow
Cancel is opposite of Capture which cancels the deduction and returns locked amount back to Payer’s card. It is important to know that the block remains for a definite period of time depending on whether this is a debit or a credit card (usually the maximum block period is 7 days for debit cards and 28 days for credit cards).
