Here you will find all the help and resources you need in order to program applications for PC2Papers API interfaces.

PC2Paper has two letter sending API's and two legacy API's that are documented for older systems that still use them. We highly recommend the usage of our SOAP or JSON API's for the creation of any new applications or integrations. 

If you would like more advice on which interface to use or if you have a requirement that you do not believe is covered by our API's please get in touch with us. We also have software which can scrape PDF files for addresses automatically provided they are in a particular format.
