> Overview of Each Payment API
- eSewa API
eSewa API enables merchants to accept payments from the eSewa wallet.
Features include:
• Wallet-based payment processing
• Redirect authentication flow
• Merchant ID integration
• Transaction verification via callback
However, eSewa API only supports its own wallet ecosystem.
If you want additional payment methods, separate integrations are required.
- Khalti API
Khalti API allows merchants to accept payments from Khalti wallet users.
It provides:
• Token-based payment verification
• Secure callback handling
• Merchant key authentication
• Sandbox testing environment
Like eSewa, Khalti API is wallet-specific and does not support other payment systems.
- ApiNepal
ApiNepal is a unified API payment gateway Nepal solution.
Instead of integrating wallets separately, ApiNepal enables:
• eSewa integration
• Khalti integration
• IME Pay integration
• Fonepay QR integration
• ConnectIPS (where applicable)
Through a single centralized API.
This structural difference makes ApiNepal unique in payment gateway comparison Nepal discussions.
> ApiNepal vs eSewa API – Detailed Comparison
| Feature | eSewa API | ApiNepal |
|---|---|---|
| Wallet Support | eSewa only | Multi-wallet |
| API Integration | Single wallet | Unified API |
| Callback Handling | eSewa specific | Standardized |
| Dashboard | eSewa panel | Centralized panel |
| Scalability | Limited to wallet | Expandable |
| Maintenance | Separate per wallet | Single maintenance layer |
- Key Insight
If your business only needs eSewa payments, eSewa API is sufficient.
If your business wants eSewa plus other wallets without building multiple integrations, ApiNepal offers better scalability.
> ApiNepal vs Khalti API – Technical Comparison
| Feature | Khalti API | ApiNepal |
|---|---|---|
| Payment Coverage | Khalti only | Multiple wallets |
| API Structure | Wallet-based | Unified structure |
| Monitoring | Khalti dashboard | Centralized reporting |
| Expansion | Requires new integration | Built-in flexibility |
| Long-Term Maintenance | Multiple APIs required | Single API layer |
- Key Insight
Khalti API works well for Khalti-only ecosystems.
ApiNepal reduces complexity when scaling to multiple payment options.
> Payment Gateway Comparison Nepal – Separate vs Unified Integration
Many merchants integrate wallets separately:
• eSewa API integration
• Khalti API integration
• Fonepay QR integration
• IME Pay integration
This results in:
• Multiple documentation references
• Different authentication flows
• Separate callback validation
• Complex reconciliation
• Increased technical debt
A unified API payment gateway Nepal approach simplifies:
• Development
• Testing
• Monitoring
• Reporting
• Security validation
• Future expansion
Unified architecture reduces long-term operational risk.
