Hi Hector,
Thank you for the question. A founding pillar in our approach to product was to focus around flexibility, our frustrations with what existed in the market were often related to hitting a roadblock in building out a solution because the connector or logic wasn’t available out of the box. A ‘connector’ in our world is really the opportunity to create a great experience around using a specific API, but what’s important is that there is always a way to pull or push the data that you need to be successful.
There have been plenty of gotchas along the way 
I think it’s easy to underestimate how quickly these integrations can scale and finding ways to make it easy for new team members to get up to speed with the mission-critical workflows that exist in their realm.
