How to Use the ClickUp Get Folder Available Fields Endpoint

The ClickUp Get Folder Available Fields API endpoint helps you discover which task fields can be used when creating or updating tasks in a specific Folder. This guide explains how to call the endpoint, what it returns, and how to use the data to build reliable, dynamic integrations.

What the ClickUp Folder Available Fields Endpoint Does

This endpoint is part of the public ClickUp REST API. It returns a list of all fields that are available for tasks within a given Folder, including:

  • Core system fields, such as status or priority
  • Custom Fields configured for that Folder
  • Information about whether a field is required, editable, or inherited

By using this information at runtime, your integration can adapt to each Workspace, Space, and Folder configuration instead of relying on hard-coded fields.

Where to Find the Official ClickUp Reference

The full technical reference for this endpoint is available in the official ClickUp API documentation. This how-to article focuses on practical usage and implementation best practices, fully aligned with the reference.

Prerequisites for Calling the ClickUp API

Before using this endpoint, make sure you have the following prerequisites in place:

  • ClickUp API token: A personal or app token with appropriate scopes.
  • Workspace access: Access to the Workspace, Space, and Folder you will query.
  • Folder ID: The numeric identifier for the Folder whose fields you want to inspect.
  • HTTP client: Such as curl, Postman, or a library in your preferred language.

ClickUp Endpoint Overview

The Get Folder Available Fields endpoint uses a GET request and follows this pattern:

GET https://api.clickup.com/api/v2/folder/{folder_id}/available_fields

Replace {folder_id} with the actual Folder ID. The response returns structured JSON describing every supported field for tasks within that Folder in ClickUp.

Required HTTP Headers for ClickUp

To authenticate and receive a proper response, include at least these headers:

  • Authorization: <your_api_token>
  • Content-Type: application/json (recommended)

Without a valid authorization header, ClickUp will return an authentication error and the request will fail.

Step-by-Step: Call the ClickUp Get Folder Available Fields Endpoint

Follow these steps to retrieve field information from your Folder.

Step 1: Locate the Folder ID in ClickUp

You need the Folder ID to build the request URL. You can obtain it by:

  • Using other API endpoints that list Spaces and Folders
  • Inspecting URLs in the web interface where the Folder is referenced

Keep the Folder ID handy, as you will insert it into the endpoint path.

Step 2: Build the Request URL for ClickUp

Once you have the Folder ID, construct the URL:

https://api.clickup.com/api/v2/folder/123456/available_fields

In this example, 123456 is the Folder ID. Replace it with your real ID.

Step 3: Send the HTTP Request

Use your preferred method to send the GET request. An example using curl might look like this:

curl -X GET 
  -H "Authorization: YOUR_CLICKUP_API_TOKEN" 
  -H "Content-Type: application/json" 
  "https://api.clickup.com/api/v2/folder/123456/available_fields"

If authentication and permissions are correct, ClickUp returns a JSON object describing the available fields.

Step 4: Inspect the Response Structure

The response contains an array of field definitions. Each element typically includes attributes such as:

  • id: The field identifier to use when creating or updating tasks
  • name: Human-readable label for the field
  • type: Data type, such as text, number, dropdown, date, or user
  • required: Whether the field must be filled in when creating a task
  • visible or similar flags: Indicate visibility and usage

Use these attributes to build forms, validation rules, and mapping logic in your integration.

Using ClickUp Folder Available Fields in Integrations

The main reason to use this endpoint is to make your solutions more resilient to configuration changes inside ClickUp. Instead of assuming which fields exist, your app can discover them on demand.

Validating Task Creation in ClickUp

Before creating a task in a Folder, you can:

  1. Call the Get Folder Available Fields endpoint.
  2. Identify which fields are required.
  3. Ensure your input data contains values for those required fields.
  4. Only send fields that exist in that Folder configuration.

This prevents validation errors and reduces maintenance when fields change in ClickUp.

Generating Dynamic Forms Based on ClickUp Fields

Many integrations and internal tools create forms that map directly to task fields. You can:

  • Fetch available fields for the Folder.
  • Render input controls based on field type.
  • Show or hide inputs depending on visibility or required flags.
  • Update your form automatically when ClickUp administrators modify fields.

This approach ensures that your form always matches the actual configuration of the Folder.

Keeping Custom Fields in Sync with ClickUp

Because Workspaces can change Custom Fields frequently, you can schedule periodic calls to this endpoint and:

  • Detect newly added Custom Fields.
  • Flag removed or deprecated fields.
  • Update internal mapping tables or schemas.

By relying on the official ClickUp definition, your integration stays aligned with how users configure their environment.

Error Handling and Best Practices for ClickUp Integrations

Robust integrations should anticipate common issues when working with the API.

Common Errors When Calling ClickUp

  • 401 Unauthorized: Invalid or missing API token in the Authorization header.
  • 403 Forbidden: Token does not have permission to access that Folder.
  • 404 Not Found: The Folder ID does not exist or is not accessible in your account.
  • 429 Too Many Requests: Rate limit exceeded; you should back off and retry later.

Always log error responses so you can troubleshoot configurations and permission problems within ClickUp.

Best Practices for Production Use in ClickUp

  • Cache the available fields for each Folder to reduce repeated calls.
  • Refresh the cache on a schedule or after relevant configuration changes.
  • Handle unknown or new field types gracefully in your code.
  • Validate data against field definitions before sending create or update requests.

These practices keep your applications efficient, scalable, and compatible with evolving ClickUp setups.

Next Steps to Improve Your ClickUp API Strategy

Once you are comfortable with the Get Folder Available Fields endpoint, extend your implementation by combining it with other endpoints that list Spaces, Folders, Lists, and tasks. Together, they provide a complete view of how work is structured inside ClickUp.
