I've to confess that ramping up on the API support in v6 has been more challenging than I thought. While past Intuiface features have been easy to absorb, APIs are a different beast. After several hours of research and tests, I'd have hoped to be more proficient by now.
Your Beginner's guide to Web Service APIs does a good job to introduce us to the basics. It's much clearer where to find the right URL and proper documentation.
Where I personally get stuck is going beyond the very basic. Let's take AirTable, which seems to be a very useful CMS service. I'm having difficulties understanding things like how to setup dynamic queries (e.g. do I need to create a separate Web API IA?), how to sort and filter results, and how to correctly deal with parameters.
Your examples are quite useful. But APIs seem to require a bit more hand holding to resonate (at least for me). I'd encourage you to consider producing video tutorials on end to end scenarios (e.g. finding an API, importing it, creating a basic UI, generating a query, picking parameters, sorting results), so we can learn how to translate our well established XLS best practices into this new world. I think going deeper with AirTable would make it a very good episode. Thanks!
