Plaid API

Plaid connects 12,000+ financial institutions to apps like Venmo and Robinhood through a single, unified API.

Plaid acts as the secure data layer for modern finance. It bridges the gap between legacy banking systems and digital apps (think Chime or Betterment) by normalizing data from thousands of global institutions. Developers use the Link module to handle user authentication: once a connection is established, the API retrieves real-time balances, transaction histories, and identity verification. It manages the complexities of MFA and credential encryption so engineering teams can ship features instead of building custom bank integrations.
