Daraja 2.0 M-Pesa Next.js & Node Starter Kit

Q: Does this starter kit handle Safaricom webhook timeouts and retries?

Yes. It uses a robust Redis queue with BullMQ workers that absorbs Safaricom webhook bursts and retries with exponential backoff, ensuring 0% dropped payment confirmations.

Q: How does it guarantee financial idempotency?

Every transaction checks and locks the unique M-Pesa receipt number in Redis with an atomic mutex lock before committing to your database. Duplicate webhooks from network lag are automatically de-duplicated.

Q: Can I integrate this into Next.js 14 App Router and Express?

Yes, it includes drop-in Route Handlers for Next.js 14/15 App Router as well as standalone Node.js Express controllers with 100% TypeScript types and Zod schemas.

Q: Does it support B2C Payouts and C2B Paybills?

Yes, Lipa na M-Pesa Online (STK Push), C2B Paybill/Buy Goods validation and confirmation URLs, and B2C salary/supplier disbursement endpoints are fully implemented with sandbox test suites.

Production-ready, battle-tested Safaricom Daraja 2.0 integration kit with idempotent webhook handling, Redis queue failover, and zero dropped callbacks.
