1. Go to your API Keys account page by clicking here (https://www.coinpayments.net/index.php?cmd=acct_api_keys).
   
2. Ideally you should create a new key to be used only by the OUGC Deposit Points plugin.
   
3. Once the key is created, you will need to edit its permissions.
   • Key Enabled should be ticked.
     
   • Withdrawal Limits You must select the Currency to use for below limits value to match the plugin's Requests Currency setting.
     
   • The following permissions are required:
     • create_withdrawal
       
     • Allow auto_confirm = 1 in create_withdrawal (not recommended unless you absolutely need it) Is required if using the Auto Confirm Withdrawals plugin setting.
       
4. Save the key permission settings.
   
5. Paste the Public Key and Private Key values to the plugin's CoinPayments Public Key and CoinPayments Private Key respectively.
   

These should be all the necessary steps in order to configure your CoinPayments API key settings for this plugin.
