Abstract: Various aspects of the disclosure relate to a unified framework application programming interface (API) to facilitate communicate between applications developed using different technology stacks. The unified framework API integrates communication functionality for each different technology stacks into unified publication and subscription API functions such that each application calls the unified framework API functions to publish information or to subscribe to receive published information. Each application publishes data using its native communication protocol and receives data in its native format, where the unified framework API performs an automatic translation of the information as needed.

Abstract: An orchestrated services layer system for a multi-tier architecture is provided. The system may include an electronic signature application programming interface (API) and an electronic signature framework. The API may receive a request for electronic signature relating to a specific transaction. The request may include an identi-authenti object that authenticates and identifies a customer, customer identification data and transaction data. The API may retrieve a template associated with the transaction data. The API may transfer the request, or a portion of the request and the template to a framework. The framework may prepare a document-to-sign by adding personalized customer information to the document, selecting a type of electronic signature and adding signature tags to the document. The framework may return the ready-to-sign document to the API. The API may forward, for signature, the ready-to-sign document to a channel associated with the customer.
