## General

The **General** section defines your API’s identity and access behavior.

### Project Name

The **Project Name** is your API’s internal reference name.

* Used for identification inside your dashboard
* Does not affect the public endpoint URL
* Can be changed at any time

This is useful when managing multiple APIs.

***

### Subdomain

The **Subdomain** determines where your API is hosted.

For example:

```
https://your-subdomain.avicenna.dev
```

Once saved, your API will be accessible through this subdomain.

<Note>
  Changing the subdomain may affect any applications currently using your endpoint.
</Note>

***

### Require Authentication

When **Require Authentication** is enabled:

* All incoming requests must include a valid API key
* Requests without a valid key will be rejected

API keys are managed in the **Authentication** section of your dashboard.

This setting is recommended for production APIs.

***

## Integrations

The **Integrations** section allows you to connect third-party services that can be used inside your endpoint flows.

Once connected, these integrations become available in relevant blocks (e.g., Generate Text, Send Email).

***

### ChatGPT

The **ChatGPT** integration enables:

* AI text generation
* AI image generation
* Prompt-based automation inside flows

Required for using the **Generate Text** block.

***

### Resend

The **Resend** integration enables:

* Sending transactional emails
* Sending broadcast emails
* Dynamic email content using variables

Required for using the **Send Email** block.

***

## Saving Changes

After modifying any settings:

1. Click **Save**
2. Changes are applied to your API project

Some changes (such as subdomain updates) may require a short propagation period before taking effect.

***

The **Settings** page centralizes your API’s identity, security configuration, and connected services, ensuring your endpoints run securely and integrate seamlessly with external tools.
