## Typical Integration Flow

1. **Authenticate**
   * Obtain a JWT access token
   * Include it in all API requests
2. **Retrieve Master Data**
   * Fetch card types, categories, products, statuses, and groups
   * Use these identifiers when ordering or managing cards
3. **Manage Customers**
   * Retrieve customer profiles
   * Create sub‑customers if required
   * Update customer contact or address details
   * Control customer lifecycle (block, unblock, close)
4. **Order Cards**
   * Submit a card order request
   * Receive an asynchronous order reference
   * Optionally register for card creation webhooks
5. **Manage Cards**
   * Retrieve cards by identifier
   * Search and list cards using pagination
   * Perform lifecycle operations such as block, unblock, cancel, or replace
6. **Receive Webhook Events**
   * Register webhook subscriptions
   * Receive real‑time event payloads when card status changes, cards are created, or replaced
7. **Retrieve Transactions**
   * Fetch transactions by customer or card
   * Apply filters such as date range, billing status, and product identifiers
