Hi and welcome!
I have a couple of questions first:
- With 'products' you refer to the product document type shown in our Hippo Go Green demo?
- With API I guess you mean the REST like API we have in the demo?
If both questions are answered with yes then my answer to your question would also be yes.
The Hippo delivery tier (HST) allows you to expose JAX-RS based API endpoints [1]. Some examples can be found in the online demo or Hippo Go Green project as we call it ourselves. I'm not sure if there is a live demo of adding products through the API, but we have code available which you can checkout and learn from once you go into this direction.
To give some further details or background. There are two ways of exposing such a REST API like endpoint.
1. Via a Content based JAX-RS pipeline, which follows a hippo document type based approach to expose content. I'm not sure if we have a piece of code available which demonstrates this.
2. Via a 'plain' based JAX-RS pipeline, which allows you to have full control over the way the API endpoint interacts with your PHP application. An piece of example code for adding products can be found in our public SVN [2].
I hope this answers your questions and do let us me know if you have any other questions!
Cheers,
Jeroen
