# FETCH

The FETCH function retrieves data from a specified URL in real time. It allows parameters and keys to be passed in order to extract specific values from the returned data. This function is commonly used to integrate external data sources, APIs, or dynamic content into calculations.

### Syntax

```javascript
FETCH(URL:string,key:string)
//fetches data from the specified URL
```

### Arguments

URL - It is used to specify the URL from which the data has to be fetched. String Argument (Required).

key- It specifies the key whose value is to be extracted. String Argument (Required).

### Example

In the report below, we have a list of Product IDs. Using the FETCH function we specify the URL, pass the product ID from our report and dynamically retrieve the associated details from a server(API call). 

Note that we have used the [CONCATENATE ](/formula-syntax/text-formatting-functions/concatenate.md)function to concatenate the URL and the Product ID to be passed to fetch the data. To extract the product name, we have used its key "title".

## 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.inforiver.com/formula-syntax/miscellaneous-functions/fetch.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.
