Getting Started with Plaid in 3 Minutes
Summary
TLDRPlaid offers a unified API for financial services, enabling access to identity verification, income information, and bank connections. It simplifies data retrieval with consistent querying across different financial institutions. Users can sign up for an account and utilize three environments: Sandbox for testing with fake data, Development for real data with limited accounts, and Production for full access with billing. The process involves generating a Link Token for user authentication and account selection via the Link UI widget, exchanging it for an access token to make API calls for services like account verification, credit lines, and personal finance apps. Plaid also supports webhooks for real-time updates and offers a dashboard for application insights.
