How to Use the ClickUp Create Chat Message API

The ClickUp Create Chat Message API endpoint lets you programmatically add messages to task comments, Chat views, and Dashboard cards so you can automate collaboration inside ClickUp workspaces.

This step-by-step guide walks you through the endpoint requirements, authentication, request format, and practical implementation details based strictly on the official API reference.

Overview of the ClickUp Create Chat Message Endpoint

The Create Chat Message endpoint is a REST API method that posts a new message into an existing chat location in your workspace. You can use it to:

  • Send automated status updates to a task comment thread.
  • Post bot notifications into a Chat view.
  • Push alerts into a Dashboard card.

The endpoint is documented here: Create Chat Message API reference.

ClickUp API Endpoint and HTTP Method

The Create Chat Message method uses a POST request to a chat-specific URL. The base format from the documentation is:

POST https://api.clickup.com/api/v2/chat/{chat_id}/message

Key points:

  • {chat_id} is the unique identifier of the chat where the message will be posted.
  • The request body must be JSON.
  • You must include your personal token as an authorization header for ClickUp API access.

Authentication for ClickUp API Requests

To call this endpoint, you need a valid ClickUp API token. The token is passed as a header using the format defined in the reference page.

Required Headers for ClickUp Chat Requests

  • Authorization: Your ClickUp personal token.
  • Content-Type: application/json

Example headers:

Authorization: <your_clickup_token>
Content-Type: application/json

Never commit your ClickUp token to public repositories or expose it in client-side code.

Required Path and Body Parameters in ClickUp

The Create Chat Message API uses a path parameter for the chat ID and a JSON body containing the message content and optional settings.

Path Parameter

  • chat_id (string): The ID of the chat, task comment thread, or Dashboard chat location you want to post to.

JSON Body Fields

Based on the official reference, the primary body fields include:

  • message (string, required): The text of the message you want to send.
  • notify_all (boolean, optional): Whether to notify all members in the chat, if supported for that location.
  • attachments (array, optional): A list of attachment objects if the endpoint supports files or links in your ClickUp plan.

Only include supported fields noted in the reference. Additional or invalid fields may cause validation errors.

Step-by-Step: Send a ClickUp Chat Message

Follow these steps to post a new message using the ClickUp API:

1. Get Your ClickUp API Token

  1. Log in to your workspace.
  2. Generate or copy your personal API token from your settings, as instructed in the API documentation.
  3. Store the token securely, such as in an environment variable.

2. Identify the Target Chat in ClickUp

You need the chat_id for the location where the message will be added. This can correspond to:

  • A task comment thread.
  • A Chat view.
  • A Dashboard card with chat capability.

Use the appropriate ClickUp API endpoints or UI methods (as described in the platform docs) to find or obtain this ID.

3. Build the Request URL

Use the standard format and insert your chat ID:

https://api.clickup.com/api/v2/chat/<chat_id>/message

Ensure the ID is URL-safe and exactly matches the value returned by other API calls in ClickUp.

4. Create the JSON Request Body

A minimal valid body typically includes only the message text:

{
  "message": "Deployment completed successfully."
}

You can add optional parameters as documented in the reference. Keep the body fields aligned with what ClickUp supports for this endpoint.

5. Send the HTTP POST Request

Use your preferred HTTP client or library. The conceptual structure is:

POST /api/v2/chat/<chat_id>/message
Host: api.clickup.com
Authorization: <your_clickup_token>
Content-Type: application/json

{
  "message": "Deployment completed successfully.",
  "notify_all": true
}

The ClickUp API will validate your token, check the chat ID, and then create the new message if everything is correct.

Understanding ClickUp API Responses

On success, the endpoint returns a JSON response that includes key details about the created message. While the exact schema is in the official reference, you can generally expect fields such as:

  • The unique ID of the message.
  • The text content that was stored.
  • Timestamps for creation.
  • User or bot information associated with the message, depending on how ClickUp logs it.

Use these values to confirm that your automation or integration is working correctly.

Common Issues When Using the ClickUp Chat Endpoint

When working with the Create Chat Message endpoint, you may encounter these issues:

Invalid or Missing ClickUp Token

If the Authorization header is missing or incorrect, the API will reject the request. Verify that:

  • The token is copied exactly from your ClickUp workspace.
  • There are no extra spaces or line breaks.
  • The token has not been revoked.

Incorrect Chat ID in ClickUp

If the chat_id is wrong or refers to a location you cannot access, the request can fail with a not found or permission error. Confirm the ID using the relevant APIs or workspace configuration tools.

Invalid Body Fields

Sending unsupported properties, wrong data types, or missing required fields can produce validation errors. Always align with the exact structure defined in the official ClickUp reference.

Best Practices for Automating Chat in ClickUp

To make your integrations reliable and maintainable, follow these practices:

  • Store your ClickUp token in secure environment variables.
  • Log request and response details for debugging, without exposing secrets.
  • Implement retry logic for transient network issues.
  • Validate message content before sending it to the API.

When you build larger workflow automations, you can combine this endpoint with others in the ClickUp platform to create complete notification and collaboration flows.

Advanced Use Cases with the ClickUp API

Using the Create Chat Message endpoint as a building block, you can design more complex systems, such as:

  • Deployment pipelines that report status to a Chat view.
  • Monitoring scripts that post alerts into a Dashboard card.
  • Chat-based summaries after bulk operations in your ClickUp space.

Each integration still relies on the same core pattern: authenticated POST requests with a valid chat ID and JSON body formatted according to the documentation.
