-- Migration: Add webhook support tables
-- Description: Tables for tracking webhook events and configurations

-- Webhook logs table - tracks all incoming webhook events
CREATE TABLE IF NOT EXISTS webhook_logs (
  id SERIAL PRIMARY KEY,
  event_id VARCHAR(255) NOT NULL UNIQUE,
  entity_type VARCHAR(100) NOT NULL,
  entity_id INTEGER NOT NULL,
  event_type VARCHAR(50) NOT NULL, -- create, update, delete
  status VARCHAR(50) NOT NULL DEFAULT 'pending', -- pending, processed, failed
  error_message TEXT,
  source_ip VARCHAR(45), -- IPv4 or IPv6 address
  user_agent TEXT, -- User agent string from request
  received_at TIMESTAMP NOT NULL DEFAULT NOW(),
  processed_at TIMESTAMP,
  processing_time_ms INTEGER,
  payload JSONB NOT NULL,
  created_at TIMESTAMP NOT NULL DEFAULT NOW(),
  updated_at TIMESTAMP NOT NULL DEFAULT NOW()
);

-- Webhook configurations table - tracks which webhooks are configured
CREATE TABLE IF NOT EXISTS webhook_configs (
  id SERIAL PRIMARY KEY,
  entity_type VARCHAR(100) NOT NULL,
  event_types JSONB NOT NULL, -- array of event types: ["create", "update", "delete"]
  is_active BOOLEAN NOT NULL DEFAULT true,
  autotask_webhook_id VARCHAR(255), -- ID from Autotask webhook registration
  created_at TIMESTAMP NOT NULL DEFAULT NOW(),
  updated_at TIMESTAMP NOT NULL DEFAULT NOW(),
  UNIQUE(entity_type)

-- Indexes for webhook_logs
CREATE INDEX IF NOT EXISTS idx_webhook_logs_event_id ON webhook_logs(event_id);

-- Indexes for webhook_configs
CREATE INDEX IF NOT EXISTS idx_webhook_configs_entity_type ON webhook_configs(entity_type);
CREATE INDEX IF NOT EXISTS idx_webhook_configs_is_active ON webhook_configs(is_active);

-- Function to update updated_at timestamp
CREATE OR REPLACE FUNCTION update_webhook_updated_at()
RETURNS TRIGGER AS $$
BEGIN

-- Triggers for updated_at
