+## 📡 API INTEGRATIONS
+
+### DeskCRM API v3
+```php
+Endpoint: https://desk.descomplicar.pt/api/
+Authentication: API Key + Bearer Token
+Rate Limit: 1000 requests/hour
+
+Entities:
+- Customers (GET, POST, PUT)
+- Invoices (GET, POST, PUT) 
+- Payments (GET, POST)
+- Projects (GET)
+```
+
+### Moloni API

+```
+
+## 🔄 SYNCHRONIZATION FLOWS
+
+### 1. Customer Sync (DeskCRM → Moloni)
+```php
+Trigger: New customer created in DeskCRM
+Process:
+1. Fetch customer data from DeskCRM
+2. Map fields to Moloni format
+3. Validate required fields
+4. Create/Update client in Moloni
+5. Store mapping in sync_mappings table
+6. Log operation result
+```
+
+### 2. Invoice Import (Moloni → DeskCRM)
+```php  
+Trigger: New invoice issued in Moloni
+Process:
+1. Fetch invoice data from Moloni
+2. Identify corresponding DeskCRM customer
+3. Map invoice fields to DeskCRM format
+4. Create invoice record in DeskCRM
+5. Update customer financial data
+6. Log operation result
+```
+
+### 3. Payment Reconciliation (Bidirectional)
+```php
+Trigger: Payment recorded in either system
+Process:
+1. Fetch payment data from source system
+2. Find matching invoice in target system  
+3. Update payment status
+4. Reconcile balances
+5. Generate reconciliation report
+```
+
