# HttpRequestData- Scoped

The HttpRequestData API provides methods to build and manipulate a REST request before applying a signature and sending it to an endpoint.

Generate outbound signing requests using these APIs in the following order:

1.  HttpRequestData: Build the API request.
2.  AuthCredential: Create a credential object or update an existing one. Use the credential to sign the request through the RequestAuthAPI class.
3.  RequestAuthAPI: Sign the request and return an HttpRequestAuthedData object.
4.  HttpRequestAuthedData: Get information about the signed request.
5.  GlideHTTPRequest: Send the signed request.

Before using these APIs, you must [configure an authentication algorithm](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/platform-security/configure-authentication-algorithm.md) to sign the request and associate it with the credential used to authenticate the request.

Use this API in scoped scripts with the `sn_auth` namespace identifier. You can instantiate this class using the constructor, or you can return an HttpRequestData object from the getHttpRequestData\(\) method in the RequestAuthAPI class.

Date: 1349333576093
```

## HttpRequestData - getDirective\(\)

## HttpRequestData - getExpiry\(\)

Returns the time in seconds before the signature expires starting when the request was signed using the generateAuth\(\) method in the RequestAuthAPI class.

The expiration is commonly set by the third-party service you are sending the request to, which overrides any value set by the setExpiry\(\) method. For example, if the expiration is set to 900 seconds by the third-party service and you use the setExpiry\(\) method to set the expiration to 300 seconds, the getExpiry\(\) method returns 900 seconds.
