# API Creator

> API Creator (API Creator), the component in the Apinizer platform that enables instant API creation from databases, scripts, or mock APIs without writing code. It has three main modules: DB-2-API (creating APIs from databases), Script-2-API (creating APIs from JavaScript/Groovy scripts), and Mock API Creator (creating mock APIs). It enables rapid API creation through form-based interfaces.

## API Creator and API Gateway Relationship

APIs created with API Creator are automatically published through API Gateway. Workflow:

```
API Creator
   │
   │ API Creation
   │ (DB-2-API / Script-2-API / Mock API)
   │
   ▼
API Gateway
   │
   │ Automatic Publishing
   │ Traffic Management
   │
   ▼
Client Requests
```
