ClickUp OAuth Access Token Guide

Integrating with ClickUp via its public API starts with secure authentication. This how-to guide walks you through using OAuth 2.0 to obtain an access token so your app can safely call the ClickUp API on behalf of a user.

Understanding ClickUp OAuth 2.0 flow

The ClickUp API uses the standard OAuth 2.0 authorization code flow. In this flow, your application redirects users to authorize access, receives an authorization code, then exchanges that code for an access token.

This process involves three main stages:

1. Register an app and obtain credentials.
2. Send users to an authorization URL.
3. Exchange the returned code for an access token.

The steps below are based strictly on the official reference documentation at ClickUp OAuth access token endpoint.

ClickUp app prerequisites

Before you can request tokens from the authorization server, you need to configure an app in the developer settings.

Core requirements for a ClickUp app

• Client ID: Identifies your application to the authorization server.
• Client Secret: A confidential value used when exchanging the authorization code.
• Redirect URI: The URL where users are redirected after they authorize your integration.

Keep your client secret safe and never expose it in client-side code or public repositories.

ClickUp authorization URL setup

Your first step in the OAuth flow is to send the user to the authorization URL. From there, they grant your app permission to access their workspace data.

Constructing the ClickUp authorization request

The authorization request is typically an HTTP GET to the authorization endpoint with query parameters. While the official token reference focuses on the exchange step, a correct authorization request usually includes:

• client_id
• redirect_uri
• response_type=code
• state (recommended for CSRF protection)

After the user approves access, the service redirects to your redirect_uri with a temporary authorization code in the query string.

ClickUp access token endpoint overview

Once you have the authorization code, you exchange it for an access token using the token endpoint described in the ClickUp API reference.

HTTP method and endpoint

The token exchange uses an HTTP POST request. Per the official documentation, the request is sent to the token endpoint described on the reference page. The request body must be URL-encoded form data with specific fields explained below.

Required ClickUp token request parameters

The access token request typically contains the following OAuth 2.0 fields, as outlined in the reference:

• client_id: Your app’s client ID.
• client_secret: Your app’s client secret.
• code: The authorization code obtained from the redirect.
• redirect_uri: Must match the value used during authorization, if required by your configuration.

Send these as application/x-www-form-urlencoded data in the POST body.

Step-by-step: Request a ClickUp access token

Follow these steps to perform the full token exchange.

1. Capture the authorization code

1. User is redirected to the authorization page and consents.
2. ClickUp redirects back to your configured redirect_uri.
3. Parse the code query parameter from the redirect URL on your server.

Do not attempt this exchange from the browser; it should run on a secure backend environment.

2. Build the ClickUp token POST request

Create a POST request to the token endpoint specified in the official documentation. Include the required parameters in the body, for example:

• client_id=YOUR_CLIENT_ID
• client_secret=YOUR_CLIENT_SECRET
• code=AUTH_CODE_FROM_REDIRECT
• redirect_uri=YOUR_REDIRECT_URI (if applicable)

Set headers such as:

• Content-Type: application/x-www-form-urlencoded

3. Send the ClickUp OAuth request

From your backend service, send the POST request with the encoded body. Common options include:

• Using curl in a shell script.
• Using fetch or axios in a Node.js server.
• Using an HTTP client in your preferred language (Python, Java, Go, etc.).

4. Handle the ClickUp token response

If the request is valid, the server responds with a JSON payload containing the access token fields described in the reference. Typical values include:

• access_token: The token you use in API calls.
• token_type: Usually Bearer.
• Additional metadata depending on the implementation.

Store the token securely. Many integrations place it in an encrypted database column associated with the authenticated user.

Using your ClickUp access token

After a successful exchange, you can call protected endpoints by passing the token in the request headers.

Authorize ClickUp API requests

Include the token in the Authorization header:

• Authorization: Bearer YOUR_ACCESS_TOKEN

Every secured endpoint you call should validate this header before returning data.

Token lifetime and renewal

The reference page focuses on obtaining an access token. Depending on the implementation details of the broader OAuth setup, you may need to handle token expiration and refresh flows. Always consult the rest of the official API documentation to confirm whether refresh tokens are provided and how long access tokens remain valid.

ClickUp OAuth security best practices

Because OAuth handles sensitive data, treat every step in the flow with care.

Secure handling of ClickUp credentials

• Store the client secret only on the server side.
• Use environment variables or a secrets manager, not hard-coded values.
• Avoid logging the full authorization code or token in plaintext.

Protect redirect URIs

• Use HTTPS for all redirect endpoints.
• Validate the state parameter, if you implement it, to mitigate CSRF risks.
• Verify that the incoming redirect path matches a registered URI.

Safely storing ClickUp tokens

• Encrypt stored tokens at rest.
• Restrict database access to only required services.
• Rotate credentials and tokens periodically when supported.

Troubleshooting ClickUp OAuth integration

When something goes wrong, error messages from the token endpoint provide clues. Common issues include invalid parameters or mismatched redirect URIs.

Typical ClickUp token errors

• Invalid client: Check your client ID and client secret.
• Invalid grant: The authorization code may be expired, already used, or incorrect.
• Redirect mismatch: Ensure the redirect URI in the token request matches what you configured.

Review each request against the official reference at ClickUp OAuth token documentation to confirm that all parameters and formats are correct.

Next steps for scaling your ClickUp integration

Once you have a reliable OAuth implementation, you can build more advanced workflows around the API. These might include automated task creation, synchronization with external systems, or analytics dashboards.
