How can I design a widget with a chart that retrieves data from a web service via http request?

Here you will find a link to our SDKs on Github. The Widget SDK has sample code and a developer's guide.
The API you wish to receive data from also needs to be setup in the Infor OS API Gateway for the widget to access it.
Note you can also look into using the Infor OS Mongoose application development tool to build widgets. https://mongoose.infor.com
