Configuration

Setting Up Credentials

Before going live, you need to configure your bKash merchant credentials in bkash-payment.js:

window.bkashCreds = {
  merchantNumber: 'YOUR_MERCHANT_ID',
  username: 'YOUR_USERNAME',
  password: 'YOUR_PASSWORD',
  appKey: 'YOUR_APP_KEY',
  appSecret: 'YOUR_APP_SECRET'
};

Environment

For testing, use sandbox credentials from bKash Developer Portal. For production, replace with live credentials.

Payment Flow

1. User enters amount and clicks payment button
2. Script generates a unique invoice ID
3. Opens bKash payment popup window
4. User completes payment on bKash platform
5. Popup closes and returns to your site

Security Notes

• All payment processing happens on bKash's secure servers
• Never store sensitive card or payment information on your site
• Always use HTTPS for production websites
• Keep your API credentials secure and never commit them to public repositories
