# Usage

Terminal Agent works as a proxy to all SensePass cloud API describes in this docs.

In addition, Terminal agent allows you to use specific API's created for the Terminal Agent software.

## Authentication

Stroing and sending Device ID in the request body is not required for all API requests, Terminal Agent stores and will append this data to your requests automatically.

## Web Server

Instead of calling our cloud API (api.sensepass.com / api.sandbox.sensepass.com) - just change the base URL of your requests to <http://localhost:8003/>

**Example**: <http://localhost:8003/api/transactions/init>

The schema of this requets is identical to the cloud API.

## 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.sensepass.com/sensepay/transaction-api/terminal-agent/usage.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.
