What is Khalti payment gateway?
A practical answer on khalti integration, written from projects I have actually shipped rather than from a spec sheet.

Khalti is a popular digital wallet in Nepal. Its API lets custom web and mobile apps take payments directly, without redirecting the user to a third-party checkout page.
In More Detail
Structurally the same three steps as eSewa: initiate a payment server-side, hand the user over to authorise it, then verify the result against Khalti's lookup endpoint before trusting it. What differs is the request format, the field names, and the exact set of statuses a payment can be in — including the pending states that resolve later and are easy to forget about.
If you accept more than one provider, keep the differences in one small adapter per gateway behind a single interface your application uses, rather than branching on the provider throughout the codebase. Otherwise every change to refund handling, reconciliation or receipt emails has to be made twice, and the two paths drift until one of them has a bug the other doesn't.
What This Means For Your Project
Same core integration pattern as eSewa — if your app needs both, plan for one shared payment-abstraction layer in the backend rather than duplicating logic for each provider.
If this came up while you were scoping a project: the services page lists what I build, pricing publishes real starting figures, how I work covers cadence and timezone overlap, and the case studies show the stack and timeline on eight real projects. Unfamiliar term? Try the glossary.
