# API credentials

After successfully creating a sandbox application on the dashboard, you will be provided with a set of essential API credentials: (`client_id` and `client_secret`). These credentials are specific to your application and are required to authenticate your app for every API request.

The `client_secret`, as its name suggests, must be stored securely to ensure that **only your servers** have access to it. This security measure is essential to safeguard your application and prevent unauthorized access or actions.

  It's important to note that sandbox applications are intended exclusively for testing purposes and come with a user limit.

When you are ready to transition to a production environment, you can activate your account on our dashboard if you use the payment solution, for other solutions please contact the Bridge Team that will create the environnement for you and you will be able to retrieve your production credentials autonomously.

> ❗️ Important

> Please refrain from using your sandbox credentials in a production environment.
