Introduction

The JSON Tool in a process enables one to issue a JSON web service call, and to save the returned data into Joget's form data and/or into the process's workflow variable. Download the demo app to try it out on your Joget DX platform.

POST Parameters (Call type = POST)	When POST Method is set to "POST Parameters", these parameters will be sent as a UrlEncodedFormEntity. When POST Method is set to "POST Parameters as JSON Payload", these parameters will be sent as a StringEntity in a form of an escaped JSON string.
Custom JSON Payload	Write your own JSON to be the payload. It will be sent as a StringEntity. This option is available only when "Custom JSON Payload" in selected.
