ClickUp Common Errors

Overview

Reference for ClickUp API v2 errors. All errors return JSON with err (message) and optionally ECODE (error code).

Error Response Format

json
{
  "err": "Space not found",
  "ECODE": "ITEM_015"
}

HTTP Status Errors

400 Bad Request

Situation Response Fix
Missing required field {"err": "Task name required"} Include name in request body
Invalid field value {"err": "Invalid priority"} Priority must be 1-4 or null
Malformed JSON {"err": "Unexpected token"} Validate JSON before sending
Invalid custom field value {"err": "Invalid value for field"} Match value to field type

401 Unauthorized — OAuth Errors

ECODE Cause Solution
OAUTH_017 Token malformed or missing Include Authorization: <token> header
OAUTH_023 Workspace not authorized for token User must re-authorize workspace in OAuth flow
OAUTH_026 Token revoked by user Generate new personal token or re-authenticate
OAUTH_027 Workspace not authorized Re-authorize via OAuth, ensuring workspace scope
OAUTH_029-045 Various workspace auth failures Re-run OAuth flow for the specific workspace
bash
# 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

bash
# 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
bash
# 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
# X-RateLimit-Remaining: 95
# X-RateLimit-Reset: 1695000060  (Unix timestamp)

500/503 Server Errors

Check ClickUp Status Page first.

bash
# Quick status check
curl -s https://status.clickup.com/api/v2/summary.json | \
  jq '.status.description'

Diagnostic Script

bash
#!/bin/bash
echo "=== ClickUp API Diagnostics ==="

# 1. Auth check
echo -n "Auth: "
HTTP_CODE=$(curl -s -o /dev/null -w "%{http_code}" \
  https://api.clickup.com/api/v2/user \
  -H "Authorization: $CLICKUP_API_TOKEN")
[ "$HTTP_CODE" = "200" ] && echo "OK" || echo "FAILED ($HTTP_CODE)"

# 2. Rate limit check
echo -n "Rate limit remaining: "
curl -s -D - https://api.clickup.com/api/v2/user \
  -H "Authorization: $CLICKUP_API_TOKEN" 2>&1 | \
  grep "X-RateLimit-Remaining" | awk '{print $2}'

# 3. Workspace access
echo "Workspaces:"
curl -s https://api.clickup.com/api/v2/team \
  -H "Authorization: $CLICKUP_API_TOKEN" | jq -r '.teams[] | "  \(.id): \(.name)"'

Error Handler Pattern

typescript
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}`);
  }
}
