From Layout to Code: Finding Custom Field IDs in Zoho Projects.

From Layout to Code: Finding Custom Field IDs in Zoho Projects.

Hello everyone!
 
Ever found yourself wondering how to get the API names and IDs of custom fields in Zoho Projects while working on custom functions?

Here’s a simple and effective way to do it! This method makes it super easy to locate the right field details whenever you need them to update using custom function.
 
Example:-
 
Let’s say you’ve created a custom Single Line field called “Material Tracking” under the Task layout, and you would like to update this field using a custom function.
 
For that, you’ll first need to fetch the module ID for the Task module using the following sample code.

getModules = invokeurl
[
url :projectsEndpointV3 + portalId + "/settings/modules"
type :GET
connection:"XXXXX"
];
info getModules;
return "success";

Once you have the module ID from the above response, use it in below sample code to retrieve the custom field details, including their API names and IDs. 

getModuleField = invokeurl
[
url :projectsEndpointV3 + portalId + "/module/" + moduleId + "/fields"
type :GET
connection:"XXXXX"
];
info getModuleField;
}
return "success";

The response will include all custom fields, along with their API names and unique IDs.

You can then use these IDs directly in your custom function code whenever you need to reference or update those fields.
 
Ensure to replace XXXXX using the Zoho Projects connection link name along with the scope ZohoProjects.custom_fields.READ and moduleId with the respective id. Screenshot of the parameter to be mapped is attached for reference.
