American Express Integrates with Plaid for API-Based Data Sharing

American Express and Plaid announced an API-based data sharing integration aimed at enhancing how customers securely connect their Amex accounts to financial apps. The integration replaces less secure screen-scraping methods with direct API connections, improving data security and transparency for cardholders. Plaid's open finance infrastructure enables consumers to connect financial accounts to thousands of fintech applications.

American Express contributes its large cardholder base and financial data infrastructure. The partnership benefits consumers by providing more reliable and secure connections to budgeting, investing, and financial management apps. The rollout began in 2023, with the collaboration expected to expand Plaid's coverage of major card networks.

The move aligns with broader industry trends toward tokenized, API-driven data sharing as financial institutions modernize their connectivity infrastructure.
