Getting Started with the ClickUp API

Ready to dive in? Here’s a quick overview of what you’ll need:

1. API Authentication: Secure your connection with API tokens.
2. Explore Endpoints: Familiarize yourself with available API endpoints for tasks, lists, spaces, and more.
3. Handle Rate Limits: Be mindful of API usage limits to ensure smooth operations.
4. Postman Collection: Use ClickUp’s Postman collection for easy API testing and exploration.

Authentication and API Access

Getting Started: API Authentication

ClickUp’s API uses two primary methods for authentication: Personal API Tokens and OAuth 2.0.

Personal API Tokens

1. Navigate to ‘Settings’ > ‘Apps’ in your ClickUp account.
2. Under “API Tokens”, click “Create new token”.
3. Copy the generated token. This will be used in the Authorization header of your API requests.

Example API request using a personal token:

OAuth 2.0 Authentication Flow

1. Register your application in the ClickUp API dashboard to obtain a Client ID and Client Secret.
2. Implement the OAuth 2.0 authorization code flow: a. Direct users to ClickUp’s authorization URL:

Copy
https://app.clickup.com/api?client_id=YOUR_CLIENT_ID&redirect_uri=YOUR_REDIRECT_URI&response_type=code

1. b. After user authorization, ClickUp redirects to your specified URI with an authorization code. Exchange the code for an access token:

bash
Copy
curl -X POST https://api.clickup.com/api/v2/oauth/token \     -d "client_id=YOUR_CLIENT_ID" \     -d "client_secret=YOUR_CLIENT_SECRET" \     -d "code=AUTHORIZATION_CODE" \     -d "grant_type=authorization_code"

1. d. The response will include an access token and refresh token.

Setting Up OAuth 2.0 for Multi-User Applications

1. In the ClickUp API dashboard, create a new OAuth application.
2. Set your redirect URI. This must match exactly in your authorization requests.
3. Obtain your Client ID and Client Secret.
4. Implement the OAuth 2.0 flow as described above.
5. Use the obtained access token in the Authorization header of API requests:

bash
Copy
curl -H "Authorization: Bearer ACCESS_TOKEN" \     -H "Content-Type: application/json" \https://api.clickup.com/api/v2/team

6. Implement token refresh logic using the refresh token when access tokens expire:

bash
Copy
curl -X POST https://api.clickup.com/api/v2/oauth/token \     -d "client_id=YOUR_CLIENT_ID" \     -d "client_secret=YOUR_CLIENT_SECRET" \     -d "refresh_token=REFRESH_TOKEN" \     -d "grant_type=refresh_token"

Key considerations:

• Store Client Secret securely; never expose it client-side.
• Implement PKCE (Proof Key for Code Exchange) for added security in public clients.
• Use state parameters in authorization requests to prevent CSRF attacks.
• Securely store and manage user tokens, preferably encrypted at rest.

By properly implementing these authentication methods, you ensure secure access to ClickUp’s API endpoints while adhering to OAuth 2.0 best practices for multi-user applications.
