Remove a content item's tag

This example demonstrates how to find item's and the manipulation of content tags.

The example uses API authentication driven from JavaScript. See Authentication APIs for alternatives.

// URL of the Pyramid installation and the path to the API 2.0 REST methods
var pyramidURL = "http://mysite.com/api2/";


// step 1: authenticate admin account and get token
// NOTE: callApi method is a generic REST method shown below.
let token = callApi("auth/authenticateUser",{
	"data":{
		"userName":"adminUser",
		"password":"abc123!"
	}
},false);

//step 2: add a tag to the system
let addedTag = callApi("content/addTag ",{
	"tagData": {
	    "tagDescription":tagName,
	    "tagType":0
	},
	"auth": token
});

let tagId = addedTag.data.modifiedList[0].id;

//step 2: find/search for a Discover item called "sales figures"
let dataDiscovery = callApi("content/findContentItem",{
	"searchParams": {
		"searchString": "sales figures",
		"filterTypes": [3],
		"searchMatchType": 2,
		"searchRootFolderType":0
	},
	"auth": token // admin token generated above
});


let itemId = dataDiscovery.data[0].id;

//step 3: bind the new tag to this report
let itemIds = callApi("content/addTagToItem ",{
	"tagUsageApiData": {
	    "itemId":itemId,
	    "tagId":tagId
	},
	"auth": token
});


//step 4: get a specific tag object using its tag id
let getTag = callApi("content/getTag",{
	"tagId": tagId,
	"auth": token
})


//step 5: remove the tag from a specific content item
let removeTagFromItem = callApi("content/removeTagFromItem ",{
	"tagUsageApiData": {
	    "itemId":itemId,
	    "tagId":tagId
	},
	"auth": token
});

//step 6: delete the tag
let deleteTag = callApi("content/deleteTag ",{
	"tagId": tagId,
	"auth": token
});

//step 7: permanently delete the content item
let purgeContentItems = callApi("content/purgeContentItems",{
	"itemIds":[folderCreation.modifiedList[0].id],
	"auth": token
});



// ##### optional generic logging method for debugging ##############
function log(msg){
	document.write(msg);
	console.log(msg);

// ##### generic REST API calling method ##############
function callApi(path,data,parseResult=true){
	var xhttp = new XMLHttpRequest();
	xhttp.open("POST", pyramidURL+path, false);
	xhttp.send(JSON.stringify(data));
	if(parseResult){
		return JSON.parse(xhttp.responseText);
