# Making request

To run a request against TCP eStreaming API you should make a proper GET request against on of the API methods, providing all required params.

## Authorization

To authorize you against the API we use `AuthToken` header, which should be passed with each and every request. You always receive one, when you register in TCP.

## Request URL

Typical request URL looks like that:

> <https://api.travelcloudpro.eu/v1/cache/shopping?searchPhrase=20181009IEVIST20181015ISTIEV&pointOfSale=UA&ptc=ADT>

Request URL consists of the following elements:

| **URL part**                    | **Description**                                        |
| ------------------------------- | ------------------------------------------------------ |

## 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://cee-systems.gitbook.io/tcpapi/estreaming-api/estreaming/making-request.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.
