You cannot delete transaction history from Google Pay
Google Pay keeps transaction records for account and payment history
You can only hide or manage some activity in your Google Account settings
Open Google Pay
Tap your profile icon
Check your transaction history
For account-level activity, open myactivity.google.com
Sign in with your Google account
Use the search or filter options to find Google Pay activity
Delete eligible activity from Google My Activity if available
Note that payment records may still remain for legal, security, or financial reasons
Contact Google Pay support if you need help with account data requests
