API · Vibe Coding

Copy and paste our documentation link. Your AI builds the whole integration.

Anyone with access to an AI tool — ChatGPT, Claude, or whatever you use — can point it at the Ledgersync docs and it writes the full banking-data integration for you. No coding expertise needed to build any fintech app you want.

What this means

Building a banking-data integration used to require a developer. Not anymore. If you can paste a link into an AI tool, you can plug live bank data into your app. This opens up the market to everyone who vibe codes and wants to build fintech — near-zero coding, powered entirely by our documentation.

The go-to-market process

Five steps from signup to live bank data.

Best framing: your AI writes it for you, you test in sandbox, then you go live.

01

Register for the API and get a sandbox key

Sign up in the developer portal and grab a sandbox key. Note: there's a quick approval step, so it isn't instant — and live keys need billing set up.

02

Point your AI tool at our docs

Paste the docs link into ChatGPT, Claude, Cursor, or whatever you use — or connect the docs directly. Your AI reads the documentation and writes the integration for you.

03

Test in our sandbox with our test banks

Run the integration against our sandbox and test banks. A bank feed has a couple of moving parts, so expect a little sandbox testing before go-live — not literally one click.

04

Add a card to go live, billed at API rates

When you're ready, add billing and switch to live keys. You're now pulling real banking data, billed at API rates.

05

Use our hosted connect link

Drop in our hosted connect link so you never have to build the bank-login screen yourself. It's handled for you.

Paste this prompt

A starter prompt to hand your AI tool.

Copy this into ChatGPT, Claude, or your AI coding tool, add your sandbox key, and let it build the integration against our documentation.

It handles the moving parts for you — client setup, the hosted connect link, signed webhooks, and pulling accounts, transactions, and statements.

Starter prompt
You are building a banking-data integration using the Ledgersync API.
Read the full API documentation at https://docs.ledgersyncappv2.com/ and generate a
complete integration for my app: register a client, initiate a bank connection using
Ledgersync's hosted connect link, handle the signed webhook events, and pull accounts,
transactions, and statements. Use my sandbox key for testing. Ask me for anything you need.
Two honest notes

So there are no surprises.

The sandbox key isn't instant

There's a quick approval step to get your sandbox key, and going live requires billing to be set up. It's fast, but it's not zero-wait.

"AI builds it" is true — with a little testing

A bank-feed integration has a couple of moving parts, so expect some sandbox testing before go-live. Your AI writes it; you verify it in sandbox, then flip to live.

One subscription — the API rate takes over

No double-billing

Built for builders

Any fintech app you can imagine.

The API and docs are ready today. Whether you're prototyping a weekend project or shipping a product, you can plug in live banking data without a developer on staff.

Point your AI at the docs, test in sandbox, add a card, and go live at API rates.

Zero coding expertise. Just paste the docs and let your AI build it.
