Is Typeform one of the companies that we could integrate with using an API to bring in the data collected into one of our Wix-housed databases?
Hi,
In general - any product/solution that exposes REST API (some url we can get information from / feed information to) should be supported in Wix Code.
For example, see this article on accessing 3rd party API:
The article is using the service fixer.io . It is possible, because the service exposes REST API - " api.fixer.io/latest" , that we can call to get information.
So bottom line - if Typeform exposes this kind of API, it should be possible 
Thank you! I will go look at that article!
