Quick Start

Get up and running in three steps.

Create an API Key

Go to the BankSync app and navigate to Workspace menu then Developers to generate your API key. See the Authentication guide for details.

Make your first API call

List your connected banks with a simple cURL command:

curl -X GET https://api.banksync.io/v1/banks \
  -H "X-API-Key: bsk_your_api_key_here"

Build your integration

Use the REST API to build custom integrations, or connect an MCP client like Claude Desktop, Cursor, or VS Code to interact with your financial data using natural language. Check out the Resources & Data Types guide to understand the data model.
