# Build BNPL into any checkout

The PayLater API is your gateway to custom, end-to-end Buy Now, Pay Later experiences — in your platform, mobile app, or point of sale. The new way to split pay.

PayLater lets shoppers in Qatar split a purchase into interest-free instalments at checkout. This reference covers everything you need to integrate: authenticating with OAuth 2.0, generating payment links, taking payments at the point of sale, tracking status, issuing refunds, and receiving real-time webhooks.

- **OAuth 2.0**: Client-credentials auth
