# ListFunctions
<a name="API_ListFunctions"></a>

Retrieves all functions associated with your AWS account in the current Region. For more information about functions, see [Working with functions](https://docs.aws.amazon.com/mediatailor/latest/ug/monetization-functions.html) in the *MediaTailor User Guide*.

## Request Syntax
<a name="API_ListFunctions_RequestSyntax"></a>

```
GET /functions?MaxResults={{MaxResults}}&NextToken={{NextToken}} HTTP/1.1
```

## URI Request Parameters
<a name="API_ListFunctions_RequestParameters"></a>

The request uses the following URI parameters.

 ** [MaxResults](#API_ListFunctions_RequestSyntax) **   <a name="mediatailor-ListFunctions-request-uri-MaxResults"></a>
The maximum number of functions that you want MediaTailor to return in response to the current request. If there are more than `MaxResults` functions, use the value of `NextToken` in the response to get the next page of results.  
The default value is 100. MediaTailor uses token-based pagination, which means that a response might contain fewer than `MaxResults` items, including 0 items, even when more results are available. To retrieve all results, you must continue making requests using the `NextToken` value from each response until the response no longer includes a `NextToken` value.  
Valid Range: Minimum value of 1. Maximum value of 100.

 ** [NextToken](#API_ListFunctions_RequestSyntax) **   <a name="mediatailor-ListFunctions-request-uri-NextToken"></a>
Pagination token returned by the list request when results exceed the maximum allowed. Use the token to fetch the next page of results.  
For the first `ListFunctions` request, omit this value. For subsequent requests, get the value of `NextToken` from the previous response and specify that value for `NextToken` in the request. Continue making requests until the response no longer includes a `NextToken` value, which indicates that all results have been retrieved.

## Request Body

## Response Elements
<a name="API_ListFunctions_ResponseElements"></a>

If the action is successful, the service sends back an HTTP 200 response.

The following data is returned in JSON format by the service.

 ** [Items](#API_ListFunctions_ResponseSyntax) **   <a name="mediatailor-ListFunctions-response-Items"></a>
A list of functions associated with your account in the current Region.  
Type: Array of [Function](API_Function.md) objects

 ** [NextToken](#API_ListFunctions_ResponseSyntax) **   <a name="mediatailor-ListFunctions-response-NextToken"></a>
Pagination token returned by the list request when results exceed the maximum allowed. Use the token to fetch the next page of results.  
For the first `ListFunctions` request, omit this value. For subsequent requests, get the value of `NextToken` from the previous response and specify that value for `NextToken` in the request. Continue making requests until the response no longer includes a `NextToken` value, which indicates that all results have been retrieved.
