Kintera yesterday announced an "upcoming open application integration platform" that appears to kinda-sorta mark the long-awaited first hint of the giant CRM providers prying open their APIs and letting outside developers build out the power of their tools for custom cases without forking over a couple grants' worth of fees. NTEN is promising a forthcoming call to get into what's really opening and what's not, but as an open API shop since day one, we'd like to welcome the big K to the party, and assure them that it's a real blast if you come in past the cloakroom. And the party only improves by more guests bringing APIs.
