Is there an example of how to use the DPS API's or a community article? I want to be able to push out articles and folios using these API's.
AEM already supports uploading articles into DPS. What are you trying to do beyond what is supported via the console?
Those APIs are not documented explicitly as they were not intended to be used.
Also, with the introduction of DPS2015 the DPS classic support will be deprecated in favour of the integration with DPS2015.
