# Create Credentials

To use the **Mobile Calendar API v1**, you must first generate an API account and credentials in the main application.

***

## Steps to Create an API Account

1. **Log in** to your main account at [app.mobile-calendar.com](https://app.mobile-calendar.com).
2. Navigate to **Integrations > REST API**.
3. Click **Add API Account**.
4. Provide the required details:
   * **Account name** – informational label for your reference.
   * **Access scopes** – select which parts of the API this account can access.
   * **IP restrictions** – optionally restrict API requests to a specific IP or range.
   * **Expiration date** – optionally set an expiry date, after which the account becomes inactive.
5. After saving, a **login key** will be generated.

## Important Security Notice

{% hint style="warning" %}
 **The password is displayed only once – at the time of creation.**\
You must copy and securely store it immediately.\
Once closed, the password cannot be retrieved again.\
If lost, you will need to generate a new API account.
{% endhint %}

***

With these credentials (clientId and clientSecret), you can authenticate and obtain a **JWT token** via the `/auth/token` endpoint to access the API.
