How to Delete Task Dependencies in ClickUp via API

The ClickUp developer platform provides a dedicated endpoint to delete task dependencies so you can manage complex workflows programmatically. This guide walks you through every detail of the Delete Dependency endpoint, including URL structure, headers, parameters, and response handling.

Understanding the ClickUp Delete Dependency Endpoint

The Delete Dependency endpoint removes an existing dependency relationship between two tasks in a workspace. It is useful when a task should no longer be blocked by another task or should no longer be marked as blocking another task.

This operation is performed with an authenticated HTTP DELETE request. No request body is required; all relevant data is passed through the URL path and query parameters.

ClickUp Delete Dependency Endpoint Overview

To remove a dependency, you call the following endpoint on the ClickUp API:

DELETE /task/<task_id>/dependency/<dependency_id>

The endpoint requires:

• A valid API token in the headers.
• A target task identifier in the URL path.
• One dependency identifier in the URL path.
• A dependency type specified as a query parameter.

This design lets you remove either a blocking or a blocked task relationship precisely.

Prerequisites for Using the ClickUp Dependency API

Before calling the Delete Dependency endpoint, make sure you have:

• An active ClickUp account with access to the target workspace and tasks.
• A personal API token or OAuth token with permission to modify tasks.
• The task_id of the task whose dependency you want to remove.
• The dependency_id of the related task in the dependency relationship.

You can obtain the task and dependency IDs from other task-related endpoints or from task URLs in the ClickUp interface, depending on your workflow.

Required Headers for ClickUp Delete Dependency Requests

Every request to the ClickUp Delete Dependency endpoint must include authentication headers. At minimum, you need:

• Authorization: Your API token.
• Content-Type: application/json (recommended for consistency, even though no body is sent).

A sample header set might look like this:

Authorization: <your_clickup_api_token>
Content-Type: application/json

URL Parameters and Query Parameters in ClickUp

The endpoint uses both path parameters and a query parameter. You must supply accurate values for the operation to succeed.

ClickUp Path Parameters

• task_id: The main task from which the dependency will be removed. This is the task currently marked as either blocking or blocked.
• dependency_id: The other task involved in the dependency relationship.

Example URL pattern:

https://api.clickup.com/api/v2/task/{task_id}/dependency/{dependency_id}

ClickUp Dependency Type Query Parameter

The Delete Dependency endpoint requires a query parameter to specify the type of dependency relationship you want to remove:

• dependency_type (string, required)

Accepted values typically indicate whether the dependency represents a blocking or blocked relationship. You must pass the correct value to match the relationship you intend to delete. If the type does not match an existing dependency between the two tasks, the API will not find the relationship to remove.

Example URL with query parameter:

https://api.clickup.com/api/v2/task/{task_id}/dependency/{dependency_id}?dependency_type=blocking

Step-by-Step: Delete a Dependency in ClickUp

Follow these steps to remove a dependency between two tasks using the ClickUp endpoint.

1. Collect Task and Dependency IDs from ClickUp

1. Identify the primary task whose dependency you want to modify.
2. Copy or retrieve its task_id from your ClickUp workspace or prior API responses.
3. Identify the related task that is either blocking or blocked.
4. Copy or retrieve its dependency_id.

2. Determine the ClickUp Dependency Type

1. Review the existing relationship between the tasks.
2. Confirm whether the relationship is a blocking dependency or a blocked dependency.
3. Select the correct value for the dependency_type query parameter based on the documented options for the endpoint.

3. Build the ClickUp Delete Dependency Request

1. Construct the endpoint URL by replacing {task_id} and {dependency_id} with real values.
2. Append the dependency_type query parameter.
3. Set the HTTP method to DELETE.
4. Add the Authorization header with your API token.

Example structure:

DELETE https://api.clickup.com/api/v2/task/123/dependency/456?dependency_type=blocking
Authorization: <your_clickup_api_token>

4. Send the ClickUp API Request

1. Use a tool such as curl, Postman, or your backend code to send the request.
2. Verify that the HTTP method is DELETE and the URL is correct.
3. Submit the request and wait for the server response.

5. Handle ClickUp Delete Dependency Responses

When the dependency is deleted successfully, the endpoint returns a status code that indicates completion, usually with an empty or minimal response body. You should:

• Check the HTTP status code for success (for example, 200 or 204, as documented).
• Implement error handling for invalid IDs, missing permissions, or incorrect dependency types.
• Log the response for auditing and debugging.

If the API returns an error, review the message and correct the request parameters or authentication token before retrying.

Best Practices for Managing ClickUp Dependencies via API

When automating workflows, it is important to manage dependencies safely. Consider the following practices:

• Always read the current task details before deleting dependencies.
• Confirm that the dependency is no longer needed from a business perspective.
• Use application logs to track when dependencies are removed.
• Implement role-based access controls around scripts that call the ClickUp API.

These habits help prevent accidental workflow disruptions when removing relationships between tasks.

Summary: Using the ClickUp Delete Dependency Endpoint Safely

The Delete Dependency endpoint is a powerful part of the ClickUp developer toolkit. By sending an authenticated DELETE request with the correct path parameters and dependency type, you can keep your task relationships aligned with real-world workflows.

Always verify task IDs, dependency IDs, and the dependency type before calling the endpoint. Combined with solid logging and permission controls, this approach ensures you manage ClickUp task dependencies reliably and securely across your automation stack.
