Leffel Consulting Payments

Developer documentation

One API to accept payments online, in person, and via ACH. Your customers stay the merchant of record — their funds, their payouts — while we run the processor complexity behind a single, stable interface.

How it works

Merchant of record

Each business is its own connected account. You never hold their funds; payouts go straight to them.

One stable API

You store one lcPaymentId and talk to one versioned REST API — no processor-specific plumbing.

Signed callbacks

We verify processor webhooks, update the ledger, and forward signed events to your app.
