# Business::US::USPS::WebTools(3pm)

Use the US Postal Service Web Tools

## NAME

Business::US::USPS::WebTools - Use the US Postal Service Web Tools

## SYNOPSIS

```
        use Business::US::USPS::WebTools;
        # see subclasses for API details
```

## DESCRIPTION

\*\*\* THIS IS ALPHA SOFTWARE \*\*\*

This is the base class for the WebTools web service from the US Postal Service. The USPS offers several services, and this module handles the parts common to all of them: making the request, getting the response, parsing error reponses, and so on. The interesting stuff happens in one of the subclasses which implement a particular service. So far, the only subclass in this distribution is `"Business::US::USPS::WebTools::AddressStandardization"`.

- new( ANONYMOUS\_HASH )

  Make the web service object. Pass is an anonymous hash with these keys:

  ```
          UserID          the user id provided by the USPS
          Password        the password provided by the USPS
          Testing         true or false, to select the right server
  ```

  If you don't pass the UserID or Password entries, `"new"` looks in the environment variables USPS\_WEBTOOLS\_USERID and USPS\_WEBTOOLS\_PASSWORD.

  If `"new"` cannot find both the User ID and the Password, it croaks.

  If you pass a true value with the Testing key, the object will use the testing server host name and the testing URL path. If the Testing key is false or not present, the object uses the live server details.

- userid

  Returns the User ID for the web service. You need to get this from the US Postal Service.

- password

  Returns the Password for the web service. You need to get this from the US Postal Service.

- url

  Returns the URL for the request to the web service. So far, all requests are GET request with all of the data in the query string.

- tx

  Returns the transaction from the Mojo::UserAgent request.

- response

  Returns the response from the web service. This is the slightly modified response. So far it only fixes up line endings and normalizes some error output for inconsistent responses from different physical servers.

- is\_error

  Returns true if the response to the last request was an error, and false otherwise.

  If the response was an error, this method sets various fields in the object:

  ```
          $self->{error}{number}
          $self->{error}{source}
          $self->{error}{description}
          $self->{error}{help_file}
          $self->{error}{help_context}
  ```

- live\_server\_host

  This is production.shippingapis.com. The modules choose this host when you have not set `"Testing"` to a true value.

- test\_server\_host

  For most APIs, this is testing.shippingapis.com. The modules choose this host when you have set `"Testing"` to a true value.
