Connect Your Card to Financial Apps with our Secure API

We recognize that many of our Card Members wish to connect their American Express® accounts to other financial service providers.


Our API lets you securely share your financial data with trusted apps and services. This connection helps you link with financial service providers that can track your spending, support accounting and tax services, or enable payments to friends and family from your checking accounts. We also provide visibility and control over which third-party financial services you share data with through our secure API, which you can manage within your account.
