From https://developers.google.com/pay/india/api/web/create-payment-method :
Important: The transaction reference ID is mandatory and must be unique for every request. This could be order number, subscription number, Bill ID, booking ID, insurance renewal reference, etc.
So it is just a reference to your system. Presumably if someone is buying something from you, you are keeping track of it in some Order table or something in MongoDb, for which you are using a unique (possibly auto-generated) Integer primary key, so just use that.
