## Key Endpoints

### Contacts

POST   /api/Contact/Query                # Query contacts (bulk)
POST   /api/Contact/Transaction          # Import contact (recommended)
```

### Gifts
```
GET    /api/Gift/:giftId                 # Get single gift
POST   /api/Gift/Query                   # Query gifts (bulk)
POST   /api/Gift/Transaction             # Import gift (recommended)
GET    /api/Gift/ByContact/:contactId    # Gifts for contact
```

### Recurring Gifts

POST   /api/RecurringGift/Query
GET    /api/RecurringGift/ByContact/:contactId
```

### Projects
```
GET    /api/Project/:projectId
POST   /api/Project/Query
```

### Tasks
```
POST   /api/Task                         # Create task

GET    /api/Task/Types                   # Get task types
```

## Best Practices

1. **Use Transaction Endpoints** for Gifts and Contacts to avoid duplicates
2. **Use Webhooks** instead of polling for updates
3. **Use Bulk Endpoints** (Query) when fetching multiple records
4. **Check Response Messages** on non-200 status codes
