How to Get Accessible Custom Fields with the ClickUp API

The ClickUp API lets you programmatically retrieve all custom fields that are available to a specific workspace, so your integrations can stay in sync with your teams and spaces. This guide walks you through the Get Accessible Custom Fields endpoint step by step, from permissions to request and response handling.

Understanding ClickUp Accessible Custom Fields

Before you call the endpoint, it helps to understand what accessible custom fields are and how they behave in the platform.

Accessible custom fields are fields that a user or token can use in a given workspace, even if those fields are defined at different levels in the hierarchy.

They can include:

• Workspace-level custom fields
• Space-level custom fields
• Folder-level or list-level custom fields
• Fields created by you or shared with you

The endpoint described in the ClickUp API documentation returns these fields in one place so you can build smarter automations, reports, and external apps.

Prerequisites for Using the ClickUp API

To get accessible custom fields, you need several prerequisites in place.

Required ClickUp Permissions and Scopes

Make sure your app or token has the correct scopes to read custom fields from the workspace.

• A valid ClickUp API token (user or app token)
• Read access to the workspace containing the fields
• Any additional scopes required by your app configuration

Without these, the request may return an authorization error or an empty result.

Endpoint Overview in ClickUp

The endpoint for getting accessible custom fields is available in the public developer documentation. You can review the full reference here: ClickUp Get Accessible Custom Fields reference.

This endpoint is read-only and is typically used when an app or integration needs to:

• Render dropdowns or selectors with all usable custom fields
• Validate custom field IDs before updating tasks
• Map external data sources to internal fields in a workspace

Key Request Properties

In the reference, you will find details such as:

• HTTP method: The request type used to call the endpoint
• Base URL: The ClickUp API base URL to prepend to the path
• Path parameters: Values like the workspace ID that you must include
• Headers: Required headers, including your authorization token

How to Call the ClickUp Accessible Custom Fields Endpoint

Use these steps to make a successful request from your integration or testing tool.

1. Identify the Workspace

You need the workspace identifier before you call the endpoint. You can obtain this from other API methods or from the app configuration if your integration already knows the workspace.

• Locate the workspace ID in your existing API responses
• Store it securely in your app configuration or environment variables

2. Prepare the Request URL

Combine the base URL with the documented path for the accessible custom fields endpoint. Insert the workspace ID into the path where required.

For example, your URL structure will typically look like:

• https://api.clickup.com/api/v2/<path-with-workspace-id>

Confirm the exact path and parameters using the official ClickUp reference page.

3. Set Required Headers

Every request to this endpoint must include the correct headers. According to the reference, the most important header is the authorization token.

• Authorization: your ClickUp API token
• Content-Type: usually application/json if you send a body

Enter these headers in your HTTP client, SDK, or server-side code before sending the request.

4. Send the Request

You can test the endpoint with tools like cURL, Postman, or your preferred HTTP client library in languages such as JavaScript, Python, or Java.

The basic flow is:

1. Open your HTTP client
2. Choose the documented HTTP method
3. Paste the full URL with the workspace ID
4. Add the required headers
5. Send the request and inspect the response

Interpreting the ClickUp Response

The response body includes details about each accessible custom field. Use this information to map, filter, or present fields in your app UI.

Common Response Properties

While field names may evolve, the response usually contains properties similar to:

• id: Unique identifier of the custom field
• name: Human-readable field name shown in the workspace
• type: Data type (for example, text, number, dropdown)
• options: Values for fields like dropdowns or labels
• required flags: Whether a field must be completed

Use the id when you create or update tasks using other ClickUp endpoints that support custom fields.

Handling Errors in ClickUp Integrations

If something goes wrong, the API returns an error status code and a response body that explains the issue.

Common errors include:

• Missing or invalid authorization token
• Using the wrong workspace ID
• Lacking permissions to read custom fields

Implement error handling in your integration to surface clear messages to users and to log details for troubleshooting.

Best Practices for Using ClickUp Custom Field Data

Once you can read accessible custom fields, apply these best practices to keep your integration reliable and maintainable.

Cache ClickUp Field Metadata

Custom field metadata usually changes less often than task data. To improve performance:

• Cache the list of accessible custom fields in your database
• Refresh the cache periodically or on demand
• Avoid calling the endpoint on every user action

Validate Field IDs Before Writes

Always confirm that a field ID you plan to use exists in the workspace’s accessible custom fields list.

• Fetch the list from the ClickUp endpoint
• Check that the ID is present and the type matches your expected value
• Only then send create or update requests to other endpoints

Design Flexible Mapping for ClickUp Fields

When you build an integration that syncs data between systems:

• Let admins choose which custom fields to map
• Store mappings by ClickUp field ID, not just by name
• Handle cases where a field is removed or renamed gracefully

Where to Learn More Beyond the ClickUp Endpoint

If you are planning a larger integration project around this feature, you may want help with architecture, optimization, or long-term maintenance.
