Patent attributes
Disclosed are example methods, systems, and devices for integrating payment API services provided by a service provider computing system with a client application. The client application running on a user device may allow a user to make payments and/or to submit payments for approval and may communicate payment information to a client computing system. If a payment is submitted for approval via the client application, the client computing system may make API calls to the service provider computing system to, for example, submit, view, and/or cancel payments. Payments may be approved by a second user using a second device. The service provider computing system initiates fund transfers for approved payments. Payments may be submitted within the operating environment of the client application without use of an application or website of the service provider.
