Add Task Dependencies in ClickUp via API

Learning how to add task dependencies in ClickUp through its API lets you automate task relationships, enforce workflows, and keep complex projects organized directly from your own systems.

This guide walks you through the official ClickUp Add Dependency endpoint, including URL structure, parameters, response details, and practical implementation tips.

What the ClickUp Add Dependency Endpoint Does

The Add Dependency endpoint creates a dependency between two existing tasks so that one task is blocked by, or waiting on, another.

In practice, use it to:

  • Block a task until another task is finished.
  • Represent task sequences in a project workflow.
  • Mirror dependency logic from other tools into ClickUp.
  • Automate dependency creation from scripts, integrations, or backend services.

The endpoint is available via HTTPS and uses a REST-style URL and JSON payload.

ClickUp API Endpoint Overview

The Add Dependency endpoint follows this pattern:

POST https://api.clickup.com/api/v2/task/<task_id>/dependency

Key points:

  • Method: POST
  • Authentication: Personal API token or OAuth2 token in request headers.
  • Base URL: https://api.clickup.com
  • API version: /api/v2

You call this endpoint for the task that will either be blocked or waiting on another task.

Required Authorization for ClickUp Requests

Every request to the ClickUp API must include a valid token in the header. You can use a workspace-level personal token for testing, or an OAuth2 access token in production applications.

Use this header format:

Authorization: <YOUR_CLICKUP_TOKEN>

Also include the appropriate Content-Type header:

Content-Type: application/json

ClickUp Add Dependency Request Structure

The Add Dependency endpoint accepts a JSON body describing the relationship between two tasks. You send the dependency type and the ID of the related task.

ClickUp dependency body parameters

The JSON payload supports these fields:

  • depends_on: (string) The ID of the task that another task depends on.
  • dependency_of: (string) The ID of the task that is dependent on another task.
  • type: (string) The dependency type, such as waiting_on or blocks, depending on how your integration is designed around the documentation.

You will typically provide one direction of the relationship in a call, specifying which task is waiting on or blocking the other.

Example ClickUp dependency request body

Below is a representative example of an Add Dependency payload. Adjust the field names and values based on the exact specification in the official docs:

{
  "depends_on": "task_id_that_must_be_done_first",
  "dependency_of": "task_id_that_is_blocked",
  "type": "waiting_on"
}

Replace each task ID with actual IDs from your ClickUp workspace.

Step-by-Step: Add a Dependency in ClickUp

Follow these steps to add a task dependency using the ClickUp API.

1. Get the required ClickUp task IDs

Before creating a dependency, you must know the task IDs. You can obtain them by:

  • Reading tasks via the ClickUp task API endpoints.
  • Copying IDs directly from the ClickUp task URL in the UI.
  • Retrieving them from your own database if you store ClickUp references there.

You will need two IDs:

  1. The task that must be completed first.
  2. The task that is blocked or waiting.

2. Choose dependency direction in ClickUp

Decide how the dependency should behave:

  • Task B depends on Task A being completed.
  • Task A blocks Task B until finished.

Using the body fields, you specify the direction so that ClickUp understands which task is the prerequisite and which one is constrained.

3. Build the ClickUp HTTP request

Construct the HTTP request with:

  • The correct URL including the primary task_id.
  • The Authorization header.
  • The JSON body describing the dependency.

An example using curl might look like this (simplified to match the documented structure):

curl -X POST \
  "https://api.clickup.com/api/v2/task/<task_id>/dependency" \
  -H "Authorization: <YOUR_CLICKUP_TOKEN>" \
  -H "Content-Type: application/json" \
  -d '{
    "depends_on": "<other_task_id>",
    "type": "waiting_on"
  }'

Ensure your JSON is valid and that the task IDs exist and belong to the same ClickUp workspace.

4. Send the request and review the ClickUp response

When the request succeeds, the API response will include information about the updated task, including its dependency details. You can use this data to:

  • Confirm the dependency was created.
  • Display updated information inside your own UI.
  • Log audit data for system integrations.

If the request fails, the API will return an error code and message that can help you correct your payload or authorization.

Handling ClickUp API Errors and Edge Cases

The Add Dependency endpoint can fail for several reasons. Common issues include:

  • Invalid or missing token: The Authorization header is absent or incorrect.
  • Nonexistent task IDs: One or both of the IDs do not match any task in ClickUp.
  • Permission issues: The token does not have access to one or more of the tasks.
  • Malformed JSON: The request body cannot be parsed by the API.

Typical HTTP status codes you may encounter include:

  • 200 / 201: Dependency successfully created.
  • 400: Invalid request, body, or parameters.
  • 401: Authentication failure.
  • 403: Insufficient permissions.
  • 404: Task not found.

Always log both the HTTP status code and the response body to simplify debugging when integrating with ClickUp.

Best Practices for Scaling ClickUp Dependencies

When building a system that creates dependencies programmatically in ClickUp, planning for reliability and maintainability is critical.

Validate tasks before dependency creation

Before calling the endpoint, validate that:

  • Both tasks exist in ClickUp.
  • They belong to projects or lists where dependencies make sense.
  • Your integration respects any workflow rules your team has established.

This prevents unnecessary failed calls and orphaned references in your own systems.

Respect ClickUp rate limits

If you create many dependencies at once, such as during a bulk migration, you should:

  • Throttle requests to stay within ClickUp rate limits.
  • Implement retry logic with exponential backoff for temporary errors.
  • Batch operations logically to avoid overwhelming your integration.

Keep dependency logic transparent

Document how your integration uses the Add Dependency endpoint so that project managers and administrators understand how task sequences in ClickUp are built and maintained. Clear documentation makes it easier to adjust workflows later.

Where to Learn More About the ClickUp API

The official reference for this endpoint and related operations is hosted in the ClickUp developer documentation. You can review parameters, sample requests, and up-to-date behavior details at the Add Dependency API reference.

If you need specialized guidance on building advanced integrations, automations, or SEO-focused documentation around the ClickUp platform, you can also work with experts at Consultevo for tailored consulting.

By following the steps in this guide and aligning closely with the official API reference, you can reliably create and manage task dependencies in ClickUp from your own applications and workflows.
