When user is trying to add $100 in wallet using ACH bank transfer then my app does multiply $100 with 100 then calling squareup api but after 1 day, it is adding $1 in wallet instead $100 . Would like to appreciate if someone tell us root cause issue here.
Have you checked the API Logs to confirm that 10000 was the amount passed to Square in the API request? 
@Bryan-Square Thanks For your support .
There was an issue in our code. Now it is working as expecting.
Glad to hear you figured it out.
