Abstract: Embodiments of the disclosure are directed to systems and methods in which verification data is written to a portable device and used to complete a transaction. The system may identify a number of trusted third-party entities computers capable of providing verification data associated with a particular user. The system may generate requests to each of the trusted third-party computers for that verification data. Upon receiving responses, the system may select an appropriate verification data from the responses received from those trusted third-party computers. The verification data is then written to a portable device, which is provided to a user with which it is associated. Once provided, the portable device may be used in a transaction conducted at a resource provider and the verification data may be caused to be displayed on a display operated by the resource provider.

Abstract: A user interface for dynamically validating at least a portion of programming codes as an application program interface (API) modification request. A first window area statically displays data definitions for one or more configurable elements for a request to be operably connected to an API. A second window area displays programming codes structured according to the data definitions for the request. The second window area also receives a first input from a user to modify the configurable elements. In response to receiving the first input, a dynamic request display area receives an instruction from the user to submit the programming codes to the API for validation. The submitted programming codes are not complete as a complete transaction request for processing by the API. The dynamic request display area displays a response substantially immediate after the programming codes are submitted, and response indicates whether the submitted programming codes are valid.
