NodeJS mobile payments integration


I’m encountering a problem when trying to initiate a payment. I get this error:

An error occured while initiating transaction Error: Hashes do not match!
at Paynow.parse (/home/ngonidzashe/project print/node_modules/paynow/dist/paynow.js:101:23)
at /home/ngonidzashe/project print/node_modules/paynow/dist/paynow.js:87:26
at process._tickCallback (internal/process/next_tick.js:68:7)

at /home/ngonidzashe/project print/routes/topup/wallet.js:39:23

Help anyone?
