Welcome Developers!

If you're a software developer, we've made it quite simple for you to integrate SimpleCertifiedMail.com into your own application. Just review the four Application Programming Interfaces (API) options below and then complete the form that follows. A representative from our Developer Group will contact you shortly.

  1. API’s for Enterprise Customers Seeking Direct Links to Our Resources. For clients seeking to integrate some or all of SimpleCertifiedMail.com resources with their applications, our full suite of web service API’s enable complete automation of requesting Certified Mail labels, delivery information, Proof of Acceptance (Electronic)©, Proof of Delivery (Electronic)© and Return Receipt (Electronic). These web services support both SOAP and REST communications protocols.
  2. Web Service. A requesting application sends all of the details of a single USPS Certified® Mail label to SimpleCertifiedMail.com through HTTPS web service SOAP and REST communications protocols. The label image is returned in real-time.
  3. Outsourced Printing. An extension of the web service interface, document data is routed into a pre-determined page template and then printed and mailed from SimpleCertifiedMail.com approved processing facilities.
  4. Batch Processing. An XML document containing the details of a batch of labels is transmitted to SimpleCertifiedMail.com via SFTP. After SimpleCertifiedMail.com generates the USPS Certified Mail® labels as images, a ZIP file of the images is sent back to the requesting application through a pre-arranged SFTP server.

For each of these interfaces, the user of your system also needs to have an account with SimpleCertifiedMail.com, consisting of an: Account Name, Username and Password. The labels that are generated become SimpleCertifiedMail.com "accountable documents", and your users will be able to log into SimpleCertifiedMail.com directly to check on their delivery status.

To work with SimpleCertifiedMail.com, you will need a partner key and test account from our Development Team. Please contact Developer Support using the form on this page and we will get back to you quickly.
