mpesa-apiM-Pesa Daraja 3.0 for TypeScript

A typed client with no runtime dependencies, for Node.js, Bun, Deno and edge runtimes.

Daraja 3.0 APIs

M-Pesa Express (STK push), C2B, B2C, Transaction Status, Account Balance and Reversal, on the current endpoints.

Web-standard APIs only, so the same client works on Node.js 22.12+, Bun, Deno and Cloudflare Workers.

Parsers turn Daraja's callbacks into typed objects, with amounts as exact integer cents.
