Current Endpoint: https://api.simplecertifiedmail.com/RESTv4.0
SimpleCertifiedMail.com's REST API exposes a number of methods that support third party integration with our service. Integrators may create certified or priority labels, and follow up by looking for status updates via our suite of tracking methods. The REST API also supports our partners who need outsourced printing services by exposing the "queuePrintItem" method that accepts a PDF representation of the piece to be printed and mailed. For more information please choose the name of a method on the left for sample input and output formats as well as additional details on required fields.
