I’ve been doing some flash/flex projects built on custom made API’s from a CMS companies. I have also been doing some prototyping against various systems that got API’s.
I am looking for what options there is out there, I have a hard time googling the API terms, as i get to much irrelevant hits, so I wonder if you can help me get an overview.
Here some of them i know of:
Google
Drupal
Mediawiki (not finished)
37Signals
Salesforce (expensive CRM stuff, has its own flextoolkit and stuff and has free developer accounts)
