2. create a custom JS function
3. add a fetch operation like await fetch('https://api.ipify.org?format=json')
4. See that browser blocks call with "CORS Missing Allow Origin" error

@gootik we'll look into this. In the meanwhile, you can hit that URL using the regular API query

Thank you @Nikhil-Nandagopal , for this specific issue we would want the call to be from the Client side not server side. so the regular API query would not be sufficient :( Unless we can force the API query to run from client rather than appsmith server?

@gootik Could you please share the exact error you notice in the browser by sharing a screenshot of the same?

Also, the implementation for extracting the JSON with a fetch for your case should be as shown below.

async myFun2 () {
	return await fetch('https://api.ipify.org?format=json').then(res => res.json())
}
