Agent Skills: Monday.com API

Monday.com API

Use the Monday.com GraphQL API via direct curl calls to manage boards, items, and project data.

Official docs: https://developer.monday.com/api-reference/

When to Use

Use this skill when you need to:

• Query boards and items from Monday.com
• Create, update, or delete items in boards
• Manage board columns and groups
• Sync data between Monday.com and other systems
• Automate project workflows

Prerequisites

1. Log in to Monday.com
2. Go to your avatar → Developers → My Access Tokens
3. Generate a new API token
4. Store it in the environment variable MONDAY_API_KEY

export MONDAY_API_KEY="your-api-token"

API Info

• GraphQL endpoint: https://api.monday.com/v2
• All requests are POST
• Requires Authorization header with API token
• Requires API-Version header (use 2024-10)

Important: When using $VAR in a command that pipes to another command, wrap the command containing $VAR in bash -c '...'. Due to a Claude Code bug, environment variables are silently cleared when pipes are used directly.

bash -c 'curl -s "https://api.example.com" -H "Authorization: Bearer $API_KEY"'

How to Use

All examples below assume you have MONDAY_API_KEY set.

1. Get Current User

Query the authenticated user's info:

Write to /tmp/monday_request.json:

{
  "query": "query { me { id name email } }"
}

Then run:

bash -c 'curl -s -X POST "https://api.monday.com/v2" --header "Authorization: ${MONDAY_API_KEY}" --header "API-Version: 2024-10" --header "Content-Type: application/json" -d @/tmp/monday_request.json'

2. List All Boards

Get all boards in your account:

Write to /tmp/monday_request.json:

{
  "query": "query { boards (limit: 10) { id name state items_count } }"
}

Then run:

bash -c 'curl -s -X POST "https://api.monday.com/v2" --header "Authorization: ${MONDAY_API_KEY}" --header "API-Version: 2024-10" --header "Content-Type: application/json" -d @/tmp/monday_request.json'

3. Get Board Details

Get a specific board with its groups and columns:

Write to /tmp/monday_request.json:

{
  "query": "query { boards (ids: <your-board-id>) { id name groups { id title } columns { id title type } } }"
}

Replace <your-board-id> with an actual board ID from the "List All Boards" response (example 2).

Then run:

bash -c 'curl -s -X POST "https://api.monday.com/v2" --header "Authorization: ${MONDAY_API_KEY}" --header "API-Version: 2024-10" --header "Content-Type: application/json" -d @/tmp/monday_request.json'

4. Get Items from a Board

Get items (rows) from a specific board:

Write to /tmp/monday_request.json:

{
  "query": "query { boards (ids: <your-board-id>) { items_page (limit: 10) { items { id name column_values { id text value } } } } }"
}

Replace <your-board-id> with an actual board ID from the "List All Boards" response (example 2).

Then run:

bash -c 'curl -s -X POST "https://api.monday.com/v2" --header "Authorization: ${MONDAY_API_KEY}" --header "API-Version: 2024-10" --header "Content-Type: application/json" -d @/tmp/monday_request.json'

5. Create a New Item

Create a new item in a board:

Write to /tmp/monday_request.json:

{
  "query": "mutation { create_item (board_id: <your-board-id>, group_id: \"<your-group-id>\", item_name: \"<your-item-name>\") { id name } }"
}

Replace the following values:

• <your-board-id>: An actual board ID from the "List All Boards" response (example 2)
• <your-group-id>: A group ID from the "Get Board Details" response (example 3, groups array)
• <your-item-name>: Your desired name for the new item

Then run:

bash -c 'curl -s -X POST "https://api.monday.com/v2" --header "Authorization: ${MONDAY_API_KEY}" --header "API-Version: 2024-10" --header "Content-Type: application/json" -d @/tmp/monday_request.json'

6. Create Item with Column Values

Create an item with specific column values:

Write to /tmp/monday_request.json:

{
  "query": "mutation ($boardId: ID!, $groupId: String!, $itemName: String!, $columnValues: JSON!) { create_item (board_id: $boardId, group_id: $groupId, item_name: $itemName, column_values: $columnValues) { id name } }",
  "variables": {
    "boardId": "<your-board-id>",
    "groupId": "<your-group-id>",
    "itemName": "<your-item-name>",
    "columnValues": "{\"status\": {\"label\": \"Working on it\"}, \"date\": {\"date\": \"2025-01-15\"}}"
  }
}

Replace the following values:

• <your-board-id>: An actual board ID from the "List All Boards" response (example 2)
• <your-group-id>: A group ID from the "Get Board Details" response (example 3, groups array)
• <your-item-name>: Your desired name for the new item

Then run:

bash -c 'curl -s -X POST "https://api.monday.com/v2" --header "Authorization: ${MONDAY_API_KEY}" --header "API-Version: 2024-10" --header "Content-Type: application/json" -d @/tmp/monday_request.json'

7. Update an Item

Update an existing item's column values:

Write to /tmp/monday_request.json:

{
  "query": "mutation ($boardId: ID!, $itemId: ID!, $columnValues: JSON!) { change_multiple_column_values (board_id: $boardId, item_id: $itemId, column_values: $columnValues) { id name } }",
  "variables": {
    "boardId": "<your-board-id>",
    "itemId": "<your-item-id>",
    "columnValues": "{\"status\": {\"label\": \"Done\"}}"
  }
}

Replace the following values:

• <your-board-id>: An actual board ID from the "List All Boards" response (example 2)
• <your-item-id>: An item ID from the "Get Items from a Board" response (example 4)

Then run:

bash -c 'curl -s -X POST "https://api.monday.com/v2" --header "Authorization: ${MONDAY_API_KEY}" --header "API-Version: 2024-10" --header "Content-Type: application/json" -d @/tmp/monday_request.json'

8. Delete an Item

Delete an item from a board:

Write to /tmp/monday_request.json:

{
  "query": "mutation { delete_item (item_id: <your-item-id>) { id } }"
}

Replace <your-item-id> with an actual item ID from the "Get Items from a Board" response (example 4).

Then run:

bash -c 'curl -s -X POST "https://api.monday.com/v2" --header "Authorization: ${MONDAY_API_KEY}" --header "API-Version: 2024-10" --header "Content-Type: application/json" -d @/tmp/monday_request.json'

9. Create a New Board

Create a new board:

Write to /tmp/monday_request.json:

{
  "query": "mutation { create_board (board_name: \"My New Board\", board_kind: public) { id name } }"
}

Then run:

bash -c 'curl -s -X POST "https://api.monday.com/v2" --header "Authorization: ${MONDAY_API_KEY}" --header "API-Version: 2024-10" --header "Content-Type: application/json" -d @/tmp/monday_request.json'

10. Search Items

Search for items across boards:

Write to /tmp/monday_request.json:

{
  "query": "query { items_page_by_column_values (limit: 10, board_id: <your-board-id>, columns: [{column_id: \"name\", column_values: [\"Task\"]}]) { items { id name } } }"
}

Replace <your-board-id> with an actual board ID from the "List All Boards" response (example 2).

Then run:

bash -c 'curl -s -X POST "https://api.monday.com/v2" --header "Authorization: ${MONDAY_API_KEY}" --header "API-Version: 2024-10" --header "Content-Type: application/json" -d @/tmp/monday_request.json'

Common Column Types

| Column Type | Value Format | |-------------|--------------| | Status | {"label": "Done"} | | Date | {"date": "2025-01-15"} | | Text | "Your text here" | | Number | "123" | | Person | {"id": 12345678} | | Dropdown | {"labels": ["Option1", "Option2"]} | | Checkbox | {"checked": true} |

Guidelines

1. Use variables for complex queries: GraphQL variables make escaping easier
2. Check column IDs: Use the board query to get exact column IDs before updating
3. API versioning: Always include API-Version header for consistent behavior
4. Rate limits: API has rate limits; add delays for bulk operations
5. Column values are JSON strings: When using column_values, pass as escaped JSON string
