Provide improved delivery of resources to a recipient entity when the recipient entity is involved in an interaction with a provider entity. One or more application programming interfaces (APIs) are utilized to identify delivery channels, and potentially substitute an original delivery channel with an alternate delivery channel. The present invention utilizes entity information, such as a recipient entity identifier, in order to determine recipient entity delivery preferences from a stored preference or from communications with the recipient entity. The system provides the resources to the recipient entity according to the preferences identified. A more efficient delivery of resources to the recipient entity is provided that improves the capacity, memory, and processing speed of the delivery systems and improve the ability to identify the identity of the recipient entity before the resources are delivered to the recipient entity.
