Front platform integrations for Sea Haven Industries. Two scheduled Lambdas:

1. **SLA Monitor** — checks Front conversations for SLA breaches and sends tiered Slack alerts
2. **User Sync** — pulls Google Workspace user profiles and syncs job title + phone to Front teammate custom fields

## Architecture

```
EventBridge (every 15 min, 8 AM-5 PM ET, Mon-Fri)
    |
    v
front-sla-monitor (Python 3.12, arm64)
    |
    +-- Secrets Manager --> front-integrations/front-api-token
    +-- Secrets Manager --> front-integrations/slack-bot-token
    |
    +-- GET Front API /inboxes --> filter to configured inboxes
    +-- GET Front API /inboxes/{id}/conversations --> open conversations
    |
    +-- DynamoDB (front-sla-alerts) --> dedup + first-run-of-day detection
    |
    +-- Morning (first run) --> summary to #front-sla-alerts
    +-- Tier 1 (1 hr) --> Slack DM assignee or #front-sla-alerts
    +-- Tier 2 (1 day) --> Slack DM Adam


EventBridge (weekdays 6:00 AM ET)
    |
    v
front-user-sync (Python 3.12, arm64)
    |
    +-- Secrets Manager --> front-integrations/google-service-account
    +-- Secrets Manager --> front-integrations/front-api-token
    |
    +-- GET Google Admin Directory API --> list users in target OUs
    +-- PATCH Front API /teammates/alt:email:{email} --> update custom_fields
```

## SLA Rules

| Tier | Threshold | Action |
|---|---|---|
| 1 | 1 business hour without reply | Slack DM the assignee, or post to #front-sla-alerts if unassigned |
| 2 | 1 business day without reply | Slack DM Adam |

Business time counts weekday hours only (Mon-Fri, Eastern time). Alerts are only sent during business hours (8 AM-5 PM ET). Overnight breaches produce a single morning summary.

## AWS Resources

- **Stack:** `front-integrations` (SAM, us-east-1)
- **Lambda:** `front-sla-monitor` — Python 3.12, arm64, 256 MB, 300s timeout, 60-day log retention
- **Lambda:** `front-user-sync` — Python 3.12, arm64, 256 MB, 300s timeout, 60-day log retention
- **DynamoDB:** `front-sla-alerts` — alert history per conversation + monitor state, 7-day TTL
- **EventBridge:** SLA check every 15 min during business hours; user sync daily at 6 AM ET weekdays

## Secrets (Secrets Manager)

| Secret | Purpose |
|---|---|
| `front-integrations/front-api-token` | Front API token (shared by both Lambdas) |
| `front-integrations/slack-bot-token` | Slack Bot User OAuth Token for SLA alerts |
| `front-integrations/google-service-account` | Google Cloud service account JSON key |

## Setup

### 1. Create the Slack App

1. Go to https://api.slack.com/apps and create **Front SLA Monitor** (see `slack-app-manifest.yaml`)
2. Add Bot Token Scopes: `chat:write`, `users:read`, `users:read.email`
3. Install to workspace, copy Bot User OAuth Token
4. Create `#front-sla-alerts` channel and invite the bot

### 2. Create a Front API Token

1. Front > Settings > Developers > API tokens
2. Create a token with conversation read + teammate read/write scope

### 3. Set Up Google Workspace Service Account

1. Enable **Admin SDK API** in Google Cloud Console
2. Create service account `front-directory-sync`, create JSON key
3. Enable Domain-Wide Delegation, copy Client ID
4. In Google Workspace Admin: Security > API Controls > Domain-Wide Delegation
5. Add Client ID with scope: `https://www.googleapis.com/auth/admin.directory.user.readonly`

### 4. Create Custom Fields in Front

1. Settings > Custom Fields > Teammates tab
2. Create: **Job Title** (String) and **Phone** (String)

### 5. Store Secrets in AWS

```bash
aws secretsmanager create-secret \
  --name "front-integrations/front-api-token" \
  --secret-string "YOUR_FRONT_API_TOKEN" \
  --region us-east-1

aws secretsmanager create-secret \
  --name "front-integrations/slack-bot-token" \
  --secret-string "xoxb-YOUR-SLACK-BOT-TOKEN" \
  --region us-east-1

aws secretsmanager create-secret \
  --name "front-integrations/google-service-account" \
  --secret-string file://path-to-service-account-key.json \
  --region us-east-1
```

### 6. Deploy

```bash
sam build
sam deploy --guided
```

Or push to `main` to trigger the GitHub Actions deploy workflow.

### 7. GitHub Actions Secrets

| Secret | Value |
|---|---|
| `AWS_DEPLOY_ROLE_ARN` | Org-wide OIDC deploy role (set after OIDC role is added) |
| `SAM_PARAMETER_OVERRIDES` | `FrontApiTokenSecretArn=arn:... SlackBotTokenSecretArn=arn:... GoogleServiceAccountSecretArn=arn:... SlackAlertChannel=CXXXXXXXXXX` |

## Manual Testing

```bash
aws lambda invoke --function-name front-sla-monitor --payload '{}' /dev/stdout --region us-east-1
aws lambda invoke --function-name front-user-sync --payload '{}' /dev/stdout --region us-east-1
```
