About SignNow

SignNow is a secure eSignature solution allowing organizations to obtain legally binding signatures from customers, partners, and employees in seconds, reducing document turnaround up to 90%. SignNow offers a range of deployment options:

  • Cloud
  • Virtual machine (VM) appliance

This paperless approach to document control allows you to electronically manage document workflow and securely store critical documents, eliminating scanners, faxes, printers, and document storage.


About REST (REpresentational State Transfer)

We designed the SignNow API in a very RESTful way, so that your consumption of it is simple and straightforward. From Wikipedia:

REST's proponents argue that the Web's scalability and growth are a direct result of a few key design principles:

  1. Application state and functionality are divided into resources
  2. Every resource is uniquely addressable using a universal syntax for use in hypermedia links
  3. All resources share a uniform interface for the transfer of state between client and resource, consisting of
  • A constrained set of well-defined operations
  • A constrained set of content types, optionally supporting code on demand
  1. A protocol which is:
  • Client-server
  • Stateless
  • Cacheable
  • Layered

REST's client/server separation of concerns simplifies component implementation, reduces the complexity of connector semantics, improves the effectiveness of performance tuning, and increases the scalability of pure server components. Layered system constraints allow intermediaries-proxies, gateways, and firewalls-to be introduced at various points in the communication without changing the interfaces between components, thus allowing them to assist in communication translation or improve performance via large-scale, shared caching.

REST enables intermediate processing by constraining messages to be self-descriptive: interaction is stateless between requests, standard methods and media types are used to indicate semantics and exchange information, and responses explicitly indicate cacheability.
