It is not possible to manipulate commerce categories using SuiteTalk. You can do it with CSV imports or by calling a RESTlet. CSV imports can get messy if you have lots of nested categories. Here is an example of a RESTlet that adds a commerce category.

This function is called via a post request:

POST:  function(datain) { addCommerceCategory(datain); }

Here is the code in a format that can be easily copied:

addCommerceCategory: function(datain) {
if (!datain) return “Missing datain”;
if (!datain.externalid) return “Missing externalid”;
if (!datain.name) return “Missing name”;
if (!datain.primaryparent) return “Missing primaryparent”;
if (!datain.pagetitle) return “Missing pagetitle”;
 
var record = nlapiCreateRecord(‘commercecategory’);
record.setFieldValue(‘name’, datain.name);
record.setFieldValue(‘catalog’, ‘1’);
if (datain.urlfragment) {
record.setFieldValue(‘urlfragment’, datain.urlfragment);
}
else {
record.setFieldValue(‘urlfragment’, datain.name.replace(/ /g, ‘-‘));
}
record.setFieldValue(‘primaryparent’, datain.primaryparent);
record.setFieldValue(‘externalid’, datain.externalid);
record.setFieldValue(‘pagetitle’, datain.pagetitle);
if (datain.metakeywords) record.setFieldValue(‘metakeywords’, datain.metakeywords);
if (datain.metadescription) record.setFieldValue(‘metadescription’, datain.metadescription);

try {
var id = nlapiSubmitRecord(record);
return id;
}
catch (ex) {
return ex.message ;
}
}
