Every provider implements the same `initiate` and `verify` interface in all six languages. Each one has a step-by-step integration guide and a full reference.

## Which to start with

- **eSewa and Khalti** cover the largest wallets.
- **NPS or Fonepay** reach most banks through one integration.
- **connectIPS** debits bank accounts directly.
- **CyberSource** only if a bank is acquiring cards for you.
- **IME Pay** only for existing IME Pay merchants; new builds use Khalti.

HBL (2C2P PACO), Prabhu Pay, Moru, CellPay and Namaste Pay have notes in [Other gateways](/docs/providers/others/) but no bundled adapter.
