# Atera Customer Management

## Overview

Customers in Atera represent the organizations you provide IT services to. Each customer can have multiple contacts (end users), agents (managed devices), contracts, and associated tickets. Proper customer management is essential for organized service delivery.

## Anti-triggers

- **The client's commercial record** — an Atera customer scopes
  monitoring, not contracts or billing. The company of record lives in
  `connectwise-psa-companies`, `autotask-crm`, `syncro-customers`, or
  `superops-clients`; onboarding a client in the wrong system is the
  expensive version of this mistake.
- **The endpoints a customer owns** — a customer owns agents; list them
  with `atera-agents` filtered by `CustomerID`.
- **Documentation about the client** — passwords, configurations, and
  procedures live in `hudu-companies` or `itglue-organizations`.

## Common Workflows

### New Customer Onboarding

1. **Create customer record** - Add company information
2. **Add primary contact** - Create main point of contact
3. **Set custom fields** - Add contract type, billing info
4. **Deploy agents** - Install on managed devices
5. **Configure alerts** - Set up monitoring profiles

### Customer Search Flow

1. **Search by name** - Query customers endpoint
2. **Filter results** - Match by domain or other criteria
3. **Get details** - Retrieve full customer record
4. **List contacts** - Get associated contacts

### Customer Deactivation

1. **Review active tickets** - Close or transfer
2. **Remove agents** - Delete from managed devices
3. **Archive data** - Export if needed for records
4. **Delete customer** - Remove from system

## Error Handling

### Common API Errors

| Code | Message | Resolution |
|------|---------|------------|
| 400 | Invalid customer ID | Verify customer exists |
| 400 | Email already exists | Contact email must be unique |
| 401 | Unauthorized | Check API key |
| 403 | Forbidden | Verify permissions |
| 404 | Customer not found | Confirm customer ID |
| 429 | Rate limited | Wait and retry (700 req/min) |

### Validation Errors

| Error | Cause | Fix |
|-------|-------|-----|
| Name required | Missing CustomerName | Add customer name |
| Email required | Missing contact email | Add email address |
| Invalid email | Malformed email address | Fix email format |
| Duplicate email | Email exists for another contact | Use unique email |

## Best Practices

1. **Use consistent naming** - Follow naming conventions
2. **Complete all fields** - Better data = better reporting
3. **Set primary contact** - Mark IsContactPerson for main contact
4. **Use custom fields** - Track contract and billing info
5. **Keep data current** - Update when information changes
6. **Audit regularly** - Review and clean stale records
7. **Link domains** - Associate email domains for routing
