ClickUp Core Workflow A — Task Management
Overview
CRUD operations on ClickUp tasks via API v2. Tasks live in Lists and support assignees, priorities (1-4), statuses, due dates, tags, checklists, and custom fields.
Endpoints
| Operation | Method | Endpoint |
|-----------|--------|----------|
| Create task | POST | /api/v2/list/{list_id}/task |
| Get task | GET | /api/v2/task/{task_id} |
| Update task | PUT | /api/v2/task/{task_id} |
| Delete task | DELETE | /api/v2/task/{task_id} |
| Get tasks in list | GET | /api/v2/list/{list_id}/task |
| Add task to list | POST | /api/v2/list/{list_id}/task/{task_id} |
| Create subtask | POST | /api/v2/list/{list_id}/task (with parent field) |
Create Task
interface CreateTaskBody {
name: string; // Required
description?: string; // Plain text
markdown_description?: string; // Markdown (use instead of description)
assignees?: number[]; // Array of user IDs
tags?: string[]; // Tag names
status?: string; // Status name (e.g., "to do", "in progress")
priority?: 1 | 2 | 3 | 4 | null; // 1=Urgent, 2=High, 3=Normal, 4=Low
due_date?: number; // Unix timestamp in milliseconds
due_date_time?: boolean; // true = show time, false = date only
start_date?: number; // Unix ms
start_date_time?: boolean;
time_estimate?: number; // Time estimate in milliseconds
notify_all?: boolean; // Notify assignees
parent?: string; // Parent task ID (creates subtask)
links_to?: string; // Task ID to link to
custom_fields?: Array<{
id: string; // Custom field UUID
value: any; // Type-dependent value
}>;
}
async function createTask(listId: string, task: CreateTaskBody) {
return clickupRequest(`/list/${listId}/task`, {
method: 'POST',
body: JSON.stringify(task),
});
}
// Example: Create an urgent task with assignee
await createTask('900100200300', {
name: 'Fix production bug in auth module',
markdown_description: '## Bug\nLogin fails for SSO users\n\n## Steps\n1. Go to /login\n2. Click SSO',
assignees: [183],
priority: 1,
status: 'in progress',
due_date: Date.now() + 3600000,
due_date_time: true,
tags: ['bug', 'production'],
});
Get Tasks (with Filtering)
async function getTasks(listId: string, params: Record<string, string> = {}) {
const query = new URLSearchParams({
archived: 'false',
include_closed: 'false',
subtasks: 'true',
...params,
});
return clickupRequest(`/list/${listId}/task?${query}`);
}
// Filter by assignee and status
const tasks = await getTasks('900100200300', {
'assignees[]': '183',
'statuses[]': 'in progress',
order_by: 'due_date',
reverse: 'true',
page: '0', // Pagination: 100 tasks per page
});
// Response: { tasks: [...] }
Update Task
// Only include fields you want to change
async function updateTask(taskId: string, updates: Partial<CreateTaskBody>) {
return clickupRequest(`/task/${taskId}`, {
method: 'PUT',
body: JSON.stringify(updates),
});
}
// Change status and add assignee
await updateTask('abc123', {
status: 'complete',
assignees: { add: [456], rem: [] }, // Add/remove pattern for assignees on update
});
Create Subtask
await createTask('900100200300', {
name: 'Write unit tests for auth fix',
parent: 'abc123', // Parent task ID makes this a subtask
assignees: [183],
priority: 3,
});
Bulk Operations
// Get all tasks across workspace with team-level endpoint
async function searchTasks(teamId: string, query: string) {
return clickupRequest(`/team/${teamId}/task?${new URLSearchParams({
page: '0',
order_by: 'updated',
reverse: 'true',
include_closed: 'true',
subtasks: 'true',
})}`);
}
Error Handling
| Status | Cause | Solution |
|--------|-------|----------|
| 400 | Missing name field | Task name is required |
| 401 | Invalid token | Re-authenticate |
| 404 | Invalid list_id or task_id | Verify IDs via GET endpoints |
| 403 | No permission on this list | Check workspace membership |
