Years ago, when designing an interface to a vendor's web services, I did the following. This isn't a genius move, but it's worth emphasizing how important it is. And what's most important isn't technical.

1. I built a simple spike solution to access their service.
2. I morphed this into a "sanity …

Some folks love the twin ideas that (1) "someone" might break the API rules and (2) they must write lots of bonus code to "prevent" problems.

I really dislike being asked to plan a project. It's hard to predict the future accurately.
