In the API tab for your app did you enable Data API for that specific datatype? And you’re not accidently cross referencing like trying to get something from live from the dev version?
Yea I mean that screenshot looks fine… how about your API Connector setup? And the actual action making the API call? Nothing changed recently? Did you edit the datatype name recently so it can’t find that key name?
ah yes, i changed name it once. but i change back again.
before i call data api root url with /obj they return json information about api,
it won’t return now. i don’t know why…
If you want to check your swagger documentation, it’s [yourdomain]/version-test/api/1.1/meta/swagger.json (or remove the version-test/ for the live version)
Also when you make changes to your datatype name or change any of those settings in the API settings you have to deploy to live for them to actually take effect for your live app
