Quick ask but think its not possible

[alphacp]

I am creating a quick little app to track lost people. They call in and give what3words and they get guidance. What i would like to do is to record at latlng of the location for future reference. is there anyway to get the return value of the following url in to a latlng field in appsheet?

https://api.what3words.com/v3/convert-to-coordinates?words=[THE.WORDS]&key=[API_KEY]

I have seen some clever stuff done with images but pretty sure I have not seen this as being possible. Is it?

Thanks
