Base URL

Our API is organized around REST. It has predictable resource-oriented URLs. We enforce HTTPS in every request to improve data security, integrity, and privacy. The API does not support HTTP. All requests contain the following base URL: 
https://api.sendforsign.com/api

Authentication

To authenticate you need to add an Authorization header with the contents of the header being Bearer 123456789 where 123456789 is your Client Token. 
Authorization: Bearer 123456789
