Bulk Deletion of Zoho Projects Using Node.js and Zoho Projects API

Bulk Deletion of Zoho Projects Using Node.js and Zoho Projects API

Zoho Projects currently does not provide a built-in option to delete multiple projects in bulk from the UI. When working with testing environments or large numbers of temporary projects, deleting them one by one becomes time-consuming.

To address this, I created a small automation using Node.js and the Zoho Projects API to programmatically delete projects.

Below are the steps I followed.

Prerequisites
• Node.js installed
• Access to Zoho Projects portal
• Zoho API Self Client for OAuth authentication

Step 1 – Install Node.js

Download and install Node.js from:
https://nodejs.org

Verify installation:

node -v
npm -v

Step 2 – Create a working directory

cd Desktop
mkdir zoho-delete-projects
cd zoho-delete-projects

Step 3 – Initialize the Node project

npm init -y

Step 4 – Install Axios (HTTP client)

npm install axios

Step 5 – Create the script file

notepad deleteProjects.js

Step 6 – Add the following script

const axios = require("axios");

const TOKEN = "YOUR_ACCESS_TOKEN";
const PORTAL_ID = "YOUR_PORTAL_ID";

function sleep(ms) {
return new Promise(resolve => setTimeout(resolve, ms));
}

async function deleteProjects() {
try {

const res = await axios.get(
`https://projectsapi.zoho.in/restapi/portal/${PORTAL_ID}/projects/`,
{
headers: {
Authorization: `Zoho-oauthtoken ${TOKEN}`
}
}
);

const projects = res.data.projects;

console.log("Projects found:", projects.length);

for (const p of projects) {

const projectId = p.id_string;

await axios.delete(
`https://projectsapi.zoho.in/restapi/portal/${PORTAL_ID}/projects/${projectId}/`,
{
headers: {
Authorization: `Zoho-oauthtoken ${TOKEN}`
}
}
);

console.log("Deleted:", p.name);

// Delay added to avoid Zoho API rate limits
await sleep(2000);
}

} catch (err) {
console.log(err.response?.data || err.message);
}
}

deleteProjects();

Step 7 – Create a Self Client in Zoho API Console

https://api-console.zoho.com

Scopes used:

ZohoProjects.projects.READ
ZohoProjects.projects.DELETE

Step 8 – Generate a Grant Token

Step 9 – Convert the Grant Token to an Access Token

curl -X POST "https://accounts.zoho.in/oauth/v2/token" ^
-d "grant_type=authorization_code" ^
-d "client_id=CLIENT_ID" ^
-d "client_secret=CLIENT_SECRET" ^
-d "redirect_uri=https://www.zoho.com" ^
-d "code=GRANT_TOKEN"

Step 10 – Copy the access_token from the response.

Step 11 – Find your Portal ID

Example:

https://projects.zoho.in/portal/yourportalname

Portal ID = yourportalname

Step 12 – Update the script

const TOKEN = "ACCESS_TOKEN";
const PORTAL_ID = "yourportalname";

Step 13 – Run the script

node deleteProjects.js

The script will fetch the list of projects and delete them sequentially while respecting Zoho API rate limits.

    • Tip of the Week: Task Sorting

      I believe that sorting of tasks helps managing the activities in a better fashion. You might second it too . By default, the tasks are listed chronologically. However, you can sort the tasks either by its title, start date, end date, priority, created by and percentage completion. All you have to do is, click the Task Sorting option and select the required criteria. Few points to be noted about task sorting: This option is available in the Classic View only (within My Tasks, Tasks & Milestones section).

    • Tip of the Week: Task Dependency (Duration in Hours)

      I hope the tip on task dependency helped in understanding how it works in Zoho Projects. In a real-time, the successor task may or may not start on the predecessor's completion date. On either case, a project management tool should allow the users to set dependency between tasks. Ain't it? In Zoho Projects, the Task Duration in Hours option allows the users to set dependency between tasks that ends and starts on the same day. The Portal Owner and Admin role users can activate this option from the

    • Tip of the Week: Drag and Drop option in Calendar

      As the thoughts flow in your mind, you plan the tasks, provide duration and assign users. While you go through the calendar later, you feel that a couple of tasks should needs to be postponed by a couple of days. Do you navigate to the Tasks & Milestones section and change the task duration? is the question I have for you. In case of YES, I would say that the task duration can be changed from the Calendar module itself. All you need to do is: Drag the task bar and Drop it on the required date. Note:
