Yes, the developer needs to learn how those integrations work, and at the same time it's not their priority. You either plan it before-hand so you'll be able to tell everything to the developer or else it becomes messy this is the place I'm trying to focus on.

CustomerLabs aims to reduce the dependency on one person out of the equation at a time. For eg: Action Recorder can let you track events on your website without writing code - No dependency on developer.

On a friendlier note: Why not try once and give your feedback?
Oh Cost: I've been suggested to increase the cost ha ha.. Rs. 500 per integration to save your dev's and digital marketers time should be good is what our hypothesis is.
