# Generate Keys and Run Sample Project




## 1. Generate the API Key



> **Note**
> API Key must be securely kept in a crypto vault on the merchant servers. The API key should never flow to the client.




### Step 1.1. Generate the Keys on SmartGateway Dashboard


1. Login to [SmartGateway Dashboard](https://dashboarduat.smartgatewayuat.hdfcbank.com/settings/Security) and navigate to API Keys
   
   Login → Payments → Settings → Security → API Keys
2. Click on ‘Create New API Key’ button
