You can use an AI tool such as ChatGPT, Claude or Cursor to build a banking data integration with the LedgerSync API. You point the AI at the LedgerSync API documentation, it writes the integration code, and you test it in sandbox before going live.
This article explains how to use "vibe coding" to build a LedgerSync integration with any AI tool.
Vibe coding means describing what you want to build in plain language and letting an AI tool write the code. The AI reads the LedgerSync API documentation and writes the integration code for the moving parts: client setup, the bank connection page, signed webhooks and data reads.
Copy and paste this prompt into your AI tool, add your sandbox key, and let it build the integration:
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.
The AI will handle: client registration, the hosted connect link (so you don't have to build a bank picker), signed webhook verification, and reading accounts, transactions and statements.
Access is reviewed. LedgerSync reviews your sandbox application before your sandbox key is issued, and live access needs its own review plus billing. Plan for this wait.
The AI writes the code, and you test it. You check that the integration works in sandbox against the test banks, then switch to Live. It is not one click.
Apply in the developer portal with the email address of your LedgerSync account. When that email belongs to an existing LedgerSync account, LedgerSync links the API to that account instead of creating a second one, so your clients and data stay where they are. For questions about how API billing fits with your current plan, contact support before you apply.
