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.

JSON Tool Properties

Configure JSON Tool

Name	Description	Screen (Click to view)
JSON URL	URL to be called.	Figure 1: Configure JSON Tool
Call Type	GET POST
POST Method	POST Parameters POST Parameters as JSON Payload Custom JSON Payload
POST Parameters	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.
Request Headers	Add name(s) and value(s) to the request header.
