ClickUp API Authentication Guide

The ClickUp developer platform lets you connect apps, workflows, and automation to your workspace, but every integration must authenticate correctly before it can access data. This guide explains how to set up secure authentication with the ClickUp API using personal tokens and OAuth 2.0 so you can start building safely and efficiently.

All details in this how-to are based on the official authentication documentation provided by the ClickUp developer site.

Understanding ClickUp API authentication options

Before writing code, you need to choose the right authentication method for your use case. The ClickUp API supports two main options, each intended for specific scenarios.

Personal token authentication in ClickUp

Use a personal token when you are:

• Building scripts or tools for your own workspace only
• Running server-side utilities that do not require user-by-user permissions
• Testing or prototyping with the ClickUp API quickly

With this method, all requests run with the permissions of the user who created the token. It is simpler than OAuth 2.0 but not suitable for public apps where multiple users must authorize individually.

OAuth 2.0 authentication with ClickUp

Use OAuth 2.0 when you are:

• Creating a public or multi-tenant app
• Allowing different users or teams to connect their own workspaces
• Needing fine-grained, user-approved access scopes

With OAuth 2.0, each user explicitly authorizes your application, and the ClickUp platform issues access tokens on a per-user basis. This is the recommended method for production-grade integrations distributed to others.

How to authenticate with a ClickUp personal token

Personal token authentication is a straightforward way to get started with the API. Follow these steps to create and use a token securely.

Step 1: Generate a personal token in ClickUp

1. Log in to your workspace on the web app.
2. Open your user settings and navigate to the section related to apps or API tokens (as described in the developer docs).
3. Create a new personal token and copy it immediately. For security reasons, you may not be able to view it again.

Store this token in a secure place such as an environment variable or a secrets manager, not directly in your code or version control.

Step 2: Add the ClickUp token to API requests

When calling the API, you must send the token in the request headers. The standard format is:

• An Authorization header where the value is the token string provided by ClickUp.
• Optionally, a Content-Type: application/json header for POST or PUT requests.

Every request made with this header will execute actions and retrieve data according to the permissions of the token owner.

Step 3: Follow security best practices with ClickUp tokens

To keep your workspace safe, follow these rules:

• Never commit tokens to public repositories.
• Do not embed tokens in client-side JavaScript or mobile apps.
• Rotate tokens periodically and immediately if you suspect exposure.
• Use different tokens for development, staging, and production environments.

If a token is compromised, revoke it from your account settings and generate a new one before updating your applications.

How to use OAuth 2.0 with ClickUp

For apps used by many people or organizations, OAuth 2.0 is the correct way to authenticate with the ClickUp API. It introduces a more advanced flow but provides stronger control and security.

Step 1: Register your ClickUp OAuth app

1. Visit the official developer portal at the ClickUp authentication documentation.
2. Create a new app and provide required details such as the app name and redirect URI.
3. After registration, note your client ID and client secret, which will be used during the OAuth exchanges.

The redirect URI must match exactly what you configure in your app and on the ClickUp developer portal, or the authorization request will fail.

Step 2: Send users to the ClickUp authorization URL

Your application must redirect users to the authorization endpoint exposed by ClickUp. In that request, include parameters such as:

• client_id: The client ID from your registered app.
• redirect_uri: Where ClickUp should send users back after approval or denial.
• state: A unique string to protect against CSRF attacks.

The user will see a consent screen explaining the access your app is requesting. If they approve, ClickUp will redirect them back to your redirect URI with an authorization code.

Step 3: Exchange the code for a ClickUp access token

Once you receive the authorization code, your backend server should:

1. Validate the state parameter to ensure it matches the value you originally sent.
2. Send a secure POST request to the ClickUp token endpoint with the authorization code, client ID, client secret, and redirect URI.
3. Receive an access token (and possibly a refresh token, depending on the implementation) from the response.

Store the tokens securely on the server side. Future API calls on behalf of that user will include the access token in the Authorization header, similar to how personal tokens are sent.

Step 4: Manage token lifecycle with ClickUp

Tokens may expire or be revoked. To keep your integration reliable:

• Handle HTTP 401 or 403 errors by re-authenticating when required.
• If refresh tokens are supported by the current ClickUp OAuth implementation, use them to obtain new access tokens without asking the user to reapprove every time.
• Offer a clear way for users to disconnect your app, revoking access on both your side and the ClickUp side if applicable.

Choosing the right ClickUp authentication method

Use these guidelines to decide which method works best for your project:

• Personal token: Ideal for internal tools, one-off scripts, admin utilities, and quick testing of the ClickUp API where a single account’s permissions are enough.
• OAuth 2.0: Best for commercial apps, integrations shared with many customers, or any scenario where each user should explicitly grant and control access to their own workspace.

You can even combine both approaches: rely on personal tokens for admin automation and use OAuth 2.0 for user-facing integrations tied directly to each person’s workspace in ClickUp.

Next steps for building with ClickUp

After setting up authentication, you can explore endpoints for tasks, lists, spaces, and more. Review request limits, error formats, and any additional security recommendations in the official documentation before deploying to production.
