In short

How do I accept Khalti payments on my website?

Register as a Khalti merchant and paste the secret key from your Khalti merchant dashboard into TolaPay's Integrations. Your app makes one call, POST /api/v1/checkouts with allowed_providers ["khalti"], and redirects to the returned URL. TolaPay initiates the KPG-2 payment, handles the return, confirms it with Khalti's lookup, marks the invoice paid and sends one signed invoice.paid webhook. The money settles to your own Khalti merchant account.

How it works
