Is it possible to add any merchant account in Google wallet Android API?

Here, you need to deploy your server as well.

1) App launches2) App asks for employerId/employeeId, typeOfUser(e.g..dummyX, dummyY) and sends to Server

Case A : typeOfUser is a employer (Mr X)- server sends merchantID of Mr.A which, which then is used for in-app billing to unlock the level1 for two ids.This should return some transactionId and payment is sent to Mr X, account- Then, send the transactionID (that just recieved ), employerId (of Mr. X) and two employeesID(for Y and Z) and google merchantId (of Mr. X, provided Mr.X has valid google wallet account).- This information will be saved on server in mySQL Db.It would be used in case B , below.

Case B : typeOfUser is a employee (Mr Y or Mr Z) - Server checks the employeeID, if its linked to any of the valid employerId.- If yes, then it returns merchantID of employer (Mr. X), which is then used to make all google in-app purchasing.Hence, all these purchasing transactions are credited to Mr.X account.
