ClickUp Task API How-To Guide

The ClickUp Tasks API lets developers programmatically create, read, update, and delete tasks so teams can automate workflows and integrate ClickUp with other systems.

This how-to guide walks you through the core endpoints, required fields, and practical examples you can use right away in your applications.

Understanding the ClickUp Tasks API basics

The Tasks API in ClickUp is organized around REST principles and uses predictable resource-oriented URLs. All responses are JSON-formatted, making it easy to use with most programming languages.

Key concepts in the ClickUp task model

Before calling the API, it is important to understand how tasks fit into the ClickUp hierarchy:

• Workspaces contain Spaces.
• Spaces contain Folders (optional) and Lists.
• Lists contain tasks.
• Tasks can have subtasks, checklists, assignees, priorities, and custom fields.

Most task endpoints require a List ID or Task ID. You can obtain these IDs from the ClickUp web app or other API endpoints.

Authentication for ClickUp API requests

All ClickUp API requests must be authenticated with an API token. The token is sent in the request header, typically as:

Authorization: <your-clickup-api-token>

Always keep your token secret and avoid hard-coding it in client-side code.

How to retrieve tasks from ClickUp

You can fetch tasks from a list or retrieve a single task by ID. This is useful for syncing ClickUp with other tools or reporting pipelines.

Get tasks in a ClickUp list

To list tasks in a specific list, use the endpoint described in the official documentation at ClickUp Tasks API docs.

Typical steps:

1. Locate the List ID in the ClickUp app or via the Lists API.
2. Send a GET request to the tasks endpoint for that list.
3. Apply query parameters to filter or paginate results.

Common query parameters include:

• page – For pagination of large result sets.
• order_by – Sort by attributes such as created or updated.
• statuses – Filter tasks by workflow status.
• include_closed – Include or exclude completed tasks.

The response contains an array of task objects, each including fields like id, name, status, priority, assignees, time_estimate, and more.

Get a single ClickUp task by ID

When you already know the Task ID, use the single-task endpoint. This is ideal for:

• Displaying task details in a custom dashboard.
• Checking the latest status before an automation runs.
• Fetching custom fields for a specific task.

The response includes detailed properties, including subtasks, custom fields, and related metadata depending on the options supported by the endpoint.

How to create tasks in ClickUp

You can create new tasks in a list to automate intake, ticketing, or project setup flows based on data from other systems.

Required fields when creating a ClickUp task

When sending a POST request to create a task, you typically must provide at least:

• name – The task name or title.
• description (optional but recommended) – Rich description or instructions.
• assignees (optional) – User IDs to assign the task.
• status – A valid status for the list’s workflow.
• priority (optional) – Priority level supported by ClickUp.
• due_date (optional) – Timestamp representing due date.

Additional optional fields may include tags, time estimates, and custom field values, depending on how your ClickUp workspace is configured.

Step-by-step: create a ClickUp task

1. Find the List ID

   Open the list in the ClickUp interface or use the Lists API to retrieve its ID.

2. Prepare your JSON payload

   Include the required task name and any optional properties such as assignees, description, and due date.

3. Send a POST request to the tasks endpoint

   Use your HTTP client or integration platform, adding the authorization header with your ClickUp API token.

4. Parse the response

   The API returns the full task object, including its new ID. Store this ID if you plan to update or delete the task later.

How to update tasks in ClickUp

To keep your data aligned across systems, you can update existing tasks in ClickUp. This includes changing the status, updating the due date, or modifying custom fields.

Partial updates to a ClickUp task

The update endpoint typically supports partial updates, so you only need to send the fields you want to change. Examples of updates include:

• Move a task from To Do to In Progress.
• Change the assignee when ownership changes.
• Adjust the priority when an urgent request comes in.
• Update the description with new details from another system.

Always check the response to confirm that the changes were applied successfully.

Workflow example: syncing status with ClickUp

A common automation pattern is syncing ticket or order status between another system and ClickUp:

1. Listen for status changes in your external system.
2. Map each external status to a corresponding ClickUp status.
3. Call the task update endpoint with the new status and Task ID.
4. Log the response or errors for monitoring.

How to delete tasks from ClickUp

You can delete tasks when they are no longer needed, subject to workspace permissions. Deleting tasks through the API should be used carefully, especially in production integrations.

Safe deletion best practices for ClickUp tasks

• Check permissions – Ensure the API token has rights to delete tasks.
• Soft-delete strategy – Consider updating a custom field or status instead of immediate deletion.
• Backups – Store task IDs and key metadata before deleting in case you need an audit trail.

After sending a delete request, verify the response code and behavior described by the ClickUp documentation.

Handling advanced ClickUp task capabilities

The Tasks API supports more advanced options so you can mirror the full power of ClickUp in your integrations.

Subtasks, checklists, and custom fields in ClickUp

Depending on the endpoint and your plan, you can work with:

• Subtasks – Create and manage child tasks for granular work tracking.
• Checklists – Manage checklist items inside a task for simple to-dos.
• Custom fields – Read and write structured data specific to your processes.

Use these features to design richer automations, such as building dynamic project templates or syncing CRM attributes into ClickUp custom fields.

Rate limits and performance considerations

When integrating heavily with ClickUp, keep these points in mind:

• Respect rate limits documented by ClickUp to avoid throttling.
• Batch reads where possible instead of making many single-task calls.
• Cache frequently-read data for short periods to reduce load.

These practices help maintain reliable, fast integrations for large teams.

Next steps for building with ClickUp

Using the Tasks API, you can connect ClickUp with CRMs, help desks, form tools, and internal applications. Start with a small proof-of-concept, then expand your automation as requirements grow.

For more detailed field definitions and up-to-date endpoint references, always refer to the official ClickUp Tasks API documentation.
