# Technical and Security Aspects

## Authentication

The Merchant API requires you to authenticate with the email and password of a user account you will have to create on the Merchant Panel. Once you request to authenticate to the [Login Endpoint](/english/api-documentation/reconciliation-api/endpoints.md#login-enpoint)**,** we will respond with a cookie called **BEARER\_TOKEN** containing a **token** you have to use in the next API calls to remain authenticated.

{% hint style="info" %}
 The **BEARER\_TOKEN** cookie will expire after 15 minutes of its last request. Otherwise, you may use the [**Logout Endpoint**](/english/api-documentation/reconciliation-api/endpoints.md#login-enpoint) to invalidate the cookie for future usage.
{% endhint %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.tupayonline.com/english/api-documentation/reconciliation-api/technical-and-security-aspects.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
