Welcome to Cashful! This guide will help you quickly onboard merchants and start accepting payments. We recommend following the step-by-step tutorial that walks through account creation, organization setup, and initiating a checkout session.
Quick Start
- Sign up and sign in to obtain a session token
- Create an organization and set it as active for the session
- Create customers and start checkout sessions or payment intents
For a guided walkthrough, see the tutorial: Merchant Onboarding
Authentication & Tokens
Authenticate using POST /authentication/sign-in/email to retrieve a session token. Include the token in the Authorization: Bearer {sessionToken} header for all protected endpoints.
