I think there is a few people that are using Airtable as a REST API data resource. Airtable is great and easy to start going, but once you deploy your application (e.g. via web app) your API Key is exposed to the world. Airtable API Key gives access to all bases you have, so that might not be a great thing.
I was insistent on using Airtable for one of my Appgyver projects, so I built this workaround using a service called pipedream.com. It is basically a wrapper on Airtable, which allows you to specify only 1 base that can be accessed and create a unique access key for this purpose only. The original API key will be stored in pipedream.com
Pipedream, seems to be in the early stages and so far seems free to use ut to a certain limit. Obviously not a production scale solution but might be useful for some further testing.
@Harri_Sarsa - might be helpful to add to Appgyver Airtable tutorial page
