I can connect to my app using the data API - in Live mode. However, is it possible to connect to the Development version?
Yes you can.
Instead of:
https://appname.bubbleapps.io/api/1.1/obj/type_name
Use:
https://appname.bubbleapps.io/version-test/api/1.1/obj/type_name
fantastic - thanks @mebeingken. I had tried something similar but I think I must have put the version-test string in the wrong part of the url…
