Account and Customer Information api diagram

  1. Within your application, the user sees a prompt requesting authorization to access their Chase accounts
  2. The application displays the secure Chase login UI by loading /aggregator-oauth/mobile/authorize in an embedded web browser.
  3. The user enters their Chase credentials and consent to data share for the accounts they select.
  4. The Chase OAuth server processes the user credentials to determine access rights, and then generates an authorization code.
  5. The Chase OAuth server sends the authorization code to the application.
  6. The application exchanges the authorization code for an access token using a Post to /aggregator-ouath/token and sends it to the Chase OAuth server.
  7. The Chase OAuth server returns an access token to the application.
  8. The application embeds the access token in the Account and Customer Information API call.
  9. Chase processes the Account and Customer Information API call and returns data to the application.
  10. The application displays the data to the user.
