# Diagnose: verify your token works
curl -s -w "\nHTTP %{http_code}\n" \
https://api.clickup.com/api/v2/user \
-H "Authorization: $CLICKUP_API_TOKEN"
403 Forbidden
| Situation | Fix |
|---|---|
| No access to space/folder/list | Verify user has access to that part of the hierarchy |
| Insufficient role permissions | Need admin role for destructive operations |
| Guest access limitation | Guests have restricted API access |
404 Not Found
# Common causes: wrong ID, deleted resource, wrong hierarchy level
# Verify the resource exists:
curl -s https://api.clickup.com/api/v2/task/TASK_ID \
-H "Authorization: $CLICKUP_API_TOKEN" | jq '.id, .name'
429 Rate Limited
Rate limits vary by plan (per token, per minute):
- Free/Unlimited/Business: 100 req/min
- Business Plus: 1,000 req/min
- Enterprise: 10,000 req/min
# Check rate limit headers on any response
curl -s -D - https://api.clickup.com/api/v2/user \
-H "Authorization: $CLICKUP_API_TOKEN" 2>&1 | grep -i ratelimit
# Headers returned:
# X-RateLimit-Limit: 100

Error Handler Pattern
async function handleClickUpError(response: Response): Promise<never> {
const body = await response.json().catch(() => ({ err: 'Unknown' }));
switch (response.status) {
case 401:
throw new Error(`Auth failed (${body.ECODE}): Re-check token or re-authorize`);
case 429: {
const resetAt = response.headers.get('X-RateLimit-Reset');
const waitMs = resetAt ? (parseInt(resetAt) * 1000 - Date.now()) : 60000;
throw new Error(`Rate limited. Retry after ${Math.ceil(waitMs / 1000)}s`);
}
case 404:
throw new Error(`Resource not found: ${body.err}`);
default:
throw new Error(`ClickUp API ${response.status}: ${body.err}`);
}
