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.
