使用Pin付款网关时，使用显示错误卡令牌的收费api只能使用一次。

Question

I am getting the following error when I use this API :

{"error":"token_already_used","error_description":"Token already used. Card tokens can only be used once, to create a charge or assign a card to a customer"}

I have a card token card_4KDerBMsGjr0Rns3rNfwCQresult which I have used in the charge API for making payments.

My account is in test mode, but when I check the dashboard page of my account in the charges page it shows that the credit card has been charged, so why am I not getting any successful response?

I have followed the docs from the website only. I am novice, using this payment gateway for the first time.

I have fixed out this problem of mine . I called exec() function twice using curl , that was the reason this error was shown
