ClickUp is one of the most feature-rich project management tools available today. It helps teams plan, organize, track and manage work across projects. With capabilities like customizable workflows, tasks, docs, goals, reminders and more, ClickUp can be the central hub for your team's work. But to truly unlock ClickUp's potential, you need to connect it to other tools you use. This is where ClickUp's robust API comes in. In this article, we'll explore the capabilities of ClickUp's API and how you can use it build custom automations and integrations.

Why Use the ClickUp API?
Here are some of the key reasons to use the ClickUp API:
Overview of ClickUp's API Capabilities
ClickUp's API allows full access to its platform capabilities. With it, you can:
- Manage projects, lists, tasks and all ClickUp entities
- Automate workflows and business logic
- Build custom reports and analytics
- Integrate with other tools your team uses
- Create custom ClickUp experiences tailored to your workflows
Here are some of the key things the API provides access to:
Automate Processes
You can use the API to automate everyday workflows and processes in ClickUp. For example, you could build a Zapier integration that automatically assigns new tasks in ClickUp based on form submissions. Or use ClickUp webhooks to trigger actions when a task status changes. The automation possibilities are endless.
Sync Data
Sync data between ClickUp and other tools you use. Create ClickUp tasks from Slack or auto-populate custom fields from your CRM. Keep the data between systems up-to-date automatically.
Enhance Functionality
Add new features to ClickUp that don't exist yet. Build browser extensions, custom reports, new visualization apps and more on top of the core ClickUp API capabilities.
Centralize Information
Pull data from multiple sources into ClickUp using the API. Centralize project information in ClickUp by importing task data from Jira, Trello, Asana and other tools. Create a single source of truth.
Custom Integrations
Build entirely new integrations with ClickUp as the hub. For example, integrate ClickUp tasks into a live chat app to allow support agents to create tasks as they chat. Or show ClickUp task statuses on a digital signage screen in the office.
As you can see, the API opens up many possibilities for customizing and extending ClickUp. Next let's look at how the API works.

How the ClickUp API Works
The ClickUp API is a REST API that uses predictable URLs and common HTTP response codes. It returns data in JSON format.
Here is a quick overview of how it works:
Authentication
To call API endpoints, you need to authenticate with an access token. You can generate a personal token on your ClickUp profile or create an OAuth app for more advanced use cases.
Pass the token in the Authorization header of API requests.
Resources
The API exposes "resources" that you can create, read, update, and delete (CRUD). For example, some resources include:
- Tasks
- Lists
- Folders
- Teams
- Goals
- Comments
You perform CRUD operations on these resources using HTTP methods like GET, POST, PUT, DELETE.
Endpoints
The API endpoints follow predictable patterns like:
Copy codeGET /task/{task_id} - Get a taskPUT /task/{task_id} - Update a taskPOST /list/{list_id}/task - Create a task in a list
It's easy to guess what an endpoint does just by the structure of the URL.
Webhooks
You can also use ClickUp webhooks to receive real-time notifications when certain events happen (e.g a task status changes). This lets you build reactive integrations.
Overall the API is well-designed and easy to work with.
Core API Capabilities
Now that you understand the basics, let's explore some of the core things you can do with the ClickUp API:
Manage Tasks
The core of ClickUp is tasks organized into lists. The API provides full CRUD (Create, Read, Update, Delete) access to tasks and lists. This includes:
- Creating tasks
- Updating task details like name, description, status, priority etc.
- Adding tasks to lists
- Changing task order and indentation
- Marking tasks as completed
- Deleting tasks
- And more!

Manage Lists
Lists in ClickUp represent task lists and kanban boards. The API provides capabilities like:
- Create, update and delete lists
- Get all the tasks in a list
- Add tasks to a list or remove them
So you can integrate list structures and task organization from other tools into ClickUp.
Users and Teams
The API allows you to manage ClickUp users and permissions programmatically:
- Invite, update or remove users
- Create and modify custom roles
- Update user permissions and access
For example, you could provision or deprovision users automatically based on data from your HR system.
Comments
The Comments API lets you add, update and fetch comments on tasks, lists and team chat posts in ClickUp. This allows you to sync comments bi-directionally with tools like Slack, GitHub, Jira and more.
Custom Fields
ClickUp allows creating custom fields to capture additional information for your tasks. The API provides access to custom fields, so you can:
- Get custom field values
- Update custom field values
- Create and delete custom fields (for developers building on ClickUp)
Relationships & Dependencies
The API provides access to the relationships between tasks like:
- Subtasks - Manage parent-child task relationships
- Dependencies - Link dependent tasks that have precedence
Time Tracking
ClickUp offers sophisticated time tracking. The API enables:
- Recording time against tasks
- Getting time reports
- Changing tracked time
- Managing timers
So you can build custom time tracking and reporting.
Attachments
Attaching files to tasks is exposed through the API as well. You can programmatically attach files from cloud storage like Google Drive or Box.
Search and Filtering
The search and filtering capabilities let you find tasks that match specific criteria. You can then sync these filtered task sets into other apps.
Much More
This just scratches the surface. Other notable API capabilities include:
- Webhooks for event-driven integrations
- Folders, spaces and hierarchy management
- Goals, key results and Objectives and Key Results (OKRs)
- Checklists and checklist items
- Due dates, reminders and scheduling
- Email notifications
- Tags and tag management
- Dependencies between tasks
- Contact and account data
- Teams, groups and permissions
- And much more
As you can see, the ClickUp API provides extensive capabilities to manipulate and extract data from ClickUp.
Example API Uses and Integrations
Now that you have a sense of what's possible, let's look at some specific examples of how you could use the API:
Sync Assigned Tasks to Google Calendar
Build a simple script that fetches all tasks assigned to a user and creates corresponding calendar events in Google Calendar to represent them. Automatically update events as task details change in ClickUp. This keeps calendars in sync.
Create GitHub Issues from ClickUp Tasks
When a task is marked "In Progress" in ClickUp, use the API to automatically create a new issue in GitHub for developers to work on. Close the issue when the task status changes to "Complete".
Generate Invoices from Logged Time
Fetch time logged on tasks through the API and automatically compile invoices based on billable hours tracked. Email invoices to clients or sync to accounting software.
ClickUp Chatbot
Build a chatbot interface using tools like Dialogflow that allows creating tasks through natural language conversations. Understand requests like "schedule a meeting for Friday at 2pm".
Automatic Lead Assignment
Create rules that watch for new tasks in certain lists and automatically assign them to sales reps based on mappings you define. Help route leads faster.
Password Reset Workflow
When a user forgets their ClickUp password, collect their email through a form on your site. Use the API to send them a password reset link from ClickUp's native system.
Custom Reporting
Pull data from ClickUp into a business intelligence tool to build custom reports. Create views like burndown charts, resource allocation over time and more.
Third-Party App Reviews
Show latest app reviews from the ClickUp Marketplace on your website using the API. Keep users up-to-date on the best new app releases.
Submit Timesheets to Payroll Apps
Developers could build an integration that submits logged hours from ClickUp to payroll apps like Gusto automatically each pay period. Smooth out the payroll process.
The possibilities are endless when you have access to a robust platform like ClickUp through API access.
Getting Started with the ClickUp API
Ready to start building with the ClickUp API? Here are a few tips to get started:
Step 1 – Get API Credentials
First, you'll need to grab API credentials:
- Navigate to the Apps section in your ClickUp profile
- Click "Create New App"
- Give the app a name and click Create
- Grab the Client ID and Client Secret
For personal apps, you can also use your personal API token found in your ClickUp profile.
The ClickUp API offers three authentication mechanisms:
API Tokens
API tokens provide personalized access to ClickUp resources owned by that user.
Each user can generate a token from their ClickUp profile settings.
API requests are then authenticated by passing this token in the header.
Copy codeAuthorization: pk_123456789_ABCD1234ABCD1234ABCD1234
OAuth 2.0
For building applications used by multiple users, ClickUp recommends OAuth 2.0 authentication.
The OAuth flow involves:
- Registering an OAuth application in ClickUp
- Redirecting users to authorize the app
- Exchanging the authorization code for an access token
- Using the access token to make API requests
This allows the app to access resources owned by each user who authorizes it.

Personal API Key
When using a personal API key, be cautious against using it in production applications used by others. If your key gets compromised, you may lose access. For multi-user apps, OAuth 2.0 is recommended.
Step 2 – Check Out the Documentation
Next, review the ClickUp Developer Documentation to get an overview of all available endpoints and capabilities. Having this handy will help you explore what's possible.

Step 3 – Make Sample API Calls
Using an API client like Postman or Insomnia, try out some sample API calls. Follow the docs to fetch a task, create a comment or update a custom field. This will familiarize you with the request formats and response structures.
Here are some test calls:
- Create a task - POST /task
- Update task name - PUT /task/{id}
- Get user details - GET /user

Plan an Integration
With the basics down, start brainstorming what kind of integration you want to build. Refer to the example ideas in this post for inspiration. Scope out something exciting and useful!
Start Small

Rome wasn't built in a day. Start by getting a very simple end-to-end integration working, even if it's just creating a task from a GET request. Get a "proof of concept" working, then iterate to add more capabilities.
Use curl or a tool like Postman to try some API requests. For example:
Copy codecurl -H "Authorization: pk_123456789" https://api.clickup.com/api/v2/user

See what information you get back for different endpoints like user, team, folder, task etc.
Leverage Webhooks
For dynamic integrations, make sure to leverage ClickUp's webhooks for real-time event monitoring. This saves you from having to poll the API constantly.
Read Sample Apps
Check out ClickUp's sample applications in their App Gallery for example implementations you can learn from. They even have open source code samples on GitHub in languages like Node, Python and C# that you can inspect. Great for jumpstarting your learning!
Create a ClickUp App
When creating a ClickUp App, it is recommended to use OAuth 2.0 authentication. Here is an overview of how OAuth 2.0 works with ClickUp:
- It uses the authorization code grant flow.
- First, you register your app in ClickUp and get a client ID and secret.
- When a user wants to sign in, you redirect them to ClickUp's OAuth URL along with your client ID.
- The user sees a consent screen and approves access to their ClickUp account.
- ClickUp redirects back with an authorization code in the callback URL.
- You exchange this authorization code for an access token via the API.
- You use the access token to make API calls on behalf of the user.
The benefits of OAuth 2.0 is that each user gets their own token, so you don't access others' data. And the user can revoke access anytime.

Step 4 - Build Something!
Once comfortable, you can start building your own scripts and apps to use the API:
- Automate repetitive processes
- Develop integrations
- Build reports
- Sync data
- And more!
The possibilities are endless once you start tapping into ClickUp's capabilities.
Conclusion
The ClickUp API opens up tremendous opportunities for automating workflows, building custom tools and centralizing your team's information. Whether you want to streamline repetitive tasks or create the next hot productivity app, the API provides the capabilities you need.
So put on your developer cape, dive into the docs and get ready to crush your productivity goals faster than a speeding bullet! Excelsior!
