multi deposit address

[pedram1995kzm]

I'm trying to generate deposit address for each account of my exchange website users by using COINEX API I've faced a real problem imagine there is 2 users in my website and USER1 wants to deposit BTC so when he clicks on generate deposit address code runs : PUT /balance/deposit/address/BTC and address displays to him. but he hasn't used this address yet suddenly USER2 wants to deposit BTC too and then code runs again: PUT /balance/deposit/address/BTC but it says { code: 318, data: { }, message: "Deposit address not used." } should USER2 wait untill USER1 completes his deposit?! it can't be like that.. any idea for solving this? how everyone make an exchange with coinex api, it doesn't make a trouble for them?

Hello, I have never used coinex multiple deposit addresses. I'm not very clear about this, as you said there shouldn't be that kind of situation. I suggest you ask an official technician
