Kanboard Skill

Overview

Kanboard uses JSON-RPC 2.0 over HTTP POST. All calls go to a single endpoint.

Auth modes

Application API skips permission checks and has no session. Use it for automation. User API respects project permissions; required for "My…" procedures.

Core Helper

Always use this shell function to call the API:

kb() {
  local method="$1"
  local params="${2:-{}}"
  local user="${KANBOARD_USER:-jsonrpc}"
  local pass="${KANBOARD_PASS:-$KANBOARD_API_TOKEN}"

  curl -s -X POST \
    -u "$user:$pass" \
    -H "Content-Type: application/json" \
    -d "{\"jsonrpc\":\"2.0\",\"method\":\"$method\",\"id\":1,\"params\":$params}" \
    "${KANBOARD_URL}/jsonrpc.php" | jq .
}

Check for errors in every response:

# Always verify result is not null/false
result=$(kb getMe | jq '.result')
if [ "$result" = "null" ] || [ "$result" = "false" ]; then
  echo "Error: $(kb getMe | jq -r '.error.message // "unknown error"')"
fi

Common Workflows

Create project with full setup

# 1. Create project
project_id=$(kb createProject '{"name":"Sprint 1"}' | jq '.result')

# 2. Add columns
kb addColumn "{\"project_id\": $project_id, \"title\": \"Backlog\"}"
kb addColumn "{\"project_id\": $project_id, \"title\": \"In Progress\", \"task_limit\": 3}"
kb addColumn "{\"project_id\": $project_id, \"title\": \"Review\"}"
kb addColumn "{\"project_id\": $project_id, \"title\": \"Done\"}"

# 3. Add swimlane
kb addSwimlane "{\"project_id\": $project_id, \"name\": \"Team Alpha\"}"

# 4. Show board
kb getBoard "{\"project_id\": $project_id}"

Move task through workflow

task_id=42
project_id=1

# Get column IDs first
columns=$(kb getColumns "{\"project_id\": $project_id}" | jq '.result')
in_progress_col=$(echo $columns | jq '[.[] | select(.title=="In Progress")][0].id')

# Move task
kb moveTaskToColumn "{
  \"project_id\": $project_id,
  \"task_id\":    $task_id,
  \"column_id\":  $in_progress_col,
  \"position\":   1
}"

Create task with subtasks

# Create parent task
task_id=$(kb createTask '{
  "title":      "Implement feature X",
  "project_id": 1,
  "priority":   2
}' | jq '.result')

# Add subtasks
kb createSubtask "{\"task_id\": $task_id, \"title\": \"Write spec\"}"
kb createSubtask "{\"task_id\": $task_id, \"title\": \"Implement\"}"
kb createSubtask "{\"task_id\": $task_id, \"title\": \"Write tests\"}"
kb createSubtask "{\"task_id\": $task_id, \"title\": \"Code review\"}"

Bulk close completed tasks

project_id=1

# Get all open tasks, close those tagged "done"
kb getAllTasks "{\"project_id\": $project_id, \"status_id\": 1}" \
  | jq -r '.result[] | select(.tags[]? == "done") | .id' \
  | while read task_id; do
      kb closeTask "{\"task_id\": $task_id}"
      echo "Closed task $task_id"
    done

Error Handling

# Robust call wrapper
kb_safe() {
  local result
  result=$(kb "$@")
  local error=$(echo "$result" | jq -r '.error // empty')
  if [ -n "$error" ]; then
    echo "❌ API Error: $(echo "$result" | jq -r '.error.message')" >&2
    return 1
  fi
  echo "$result" | jq '.result'
}

# Usage
kb_safe getAllProjects
kb_safe getTask '{"task_id": 99999}'  # returns error if not found

Setup & Configuration

Add to your OpenClaw environment:

# Required
export KANBOARD_URL="https://kanboard.example.com"
export KANBOARD_API_TOKEN="your_token_from_settings_page"

# Optional (for User API / "My…" procedures)
export KANBOARD_USER="your_username"
export KANBOARD_PASS="your_password_or_personal_token"

Getting your API token:

1. Log in to Kanboard as admin
2. Go to Settings → API
3. Copy the token shown there

Personal API token (User API):

1. Click your profile avatar → My Profile
2. Click "Generate a new API token" in the API section
3. Use as KANBOARD_PASS with your username as KANBOARD_USER

Notes

• All dates use YYYY-MM-DD format or Unix timestamps
• Task priority: 0=low, 1=normal, 2=high, 3=urgent
• Kanboard supports batch requests — multiple JSON-RPC calls in one HTTP request (useful for bulk ops)
• status_id for tasks: 1=open, 2=closed
• API endpoint is always <KANBOARD_URL>/jsonrpc.php
