# Credential

Credentials pertain to the details utilized to authenticate the identity of a user or system, allowing them access to particular resources or services. In the context of a payment gateway, these credentials might encompass a username and password or API keys employed to validate the identity of the individual or system initiating a payment request. This safeguards that only authorized individuals can execute payments and access confidential financial data.

### Sandbox Credential

{% hint style="info" %}
This credential is intended to be use during development or integration stage. Any request will be process as a mock transaction and contained within the sandbox environment.
{% endhint %}

The information provided below for sandbox credentials can be utilized to test general API connectivity during development. These credentials will accept generic requests and return generic responses. If you require specific responses based on transactions, it is advisable to obtain a Sandbox API key from your Onboarding Dashboard.
