I want to update a task in zoho project api

I want to update a task in zoho project api.

I am passing custom item values but it is not updating properly.

How do I pass the value to update?

I am attaching a picture, the value of Body is dummy.

My guess is that it is because of the way the Body value is passed.

I am not very good at English.

Sorry if it is hard to read.

Announcing the Zoho Projects API
Today we're excited to announce the API for Zoho Projects where any developer can extend the project management and collaboration capabilities through our APIs and can build their own customized applications for their business needs. We've tried to make the API follow the REST (Representational State Transfer) principles and generate a XML/ JSON object which allows you to access / read / write Zoho Projects data from third-party systems like Google/Yahoo gadgets, web sites, billing & invoicing systems,
Have you moved to REST API?
Dear API Users, The Documentation of our Rest API is available here . All future development will be done to this version. We are deprecating the older API today. Its documentation will no longer be available and we will also be stopping the calls to this API soon. Thanks, Prasanna
