My Kentico EMS API Deep Dive Presentation


Introduction

A few people asked me to provide my presentation from the Kentico User Group webinar that I presented at this past week. I have attached the presentation to this blog post.  I think it went really well considering the amount of people that attended and the feedback that I received from it.

Remember there is a great tip in there for how to use the new Kentico 8.2 MacroRuleInstanceTranslator class to optimize your contact group rebuild time and lead scoring calculation time for when you have a large volume of contacts in your Kentico instance.

The deck is embedded and can be downloaded from this post after the jump.
