SYNOPSIS

use WebService::HMRC::HelloWorld;
my $hmrc = WebService::HMRC::HelloWorld->new();

# Hello World endpoint requires no authorisation
my $result = $hmrc->hello_world()
print $result->data->{message} if $result->is_success;

# Hello Application endpoint requires a server token
$hmrc->auth->server_token( $my_server_token );
$result = $hmrc->hello_application();
print $result->data->{message} if $result->is_success;

# Hello User endpoint requires an access token
$hmrc->auth->access_token( $my_access_token );
$result = $hmrc->hello_user();
print $result->data->{message} if $result->is_success;

DESCRIPTION

Perl module to interact with the UK's HMRC Making Tax Digital `Hello World` API. This is often used as a basic test of configuration and credentials before using their more involved APIs for managing corporate and personal tax affairs.

For more information, see: https://developer.service.hmrc.gov.uk/api-documentation/docs/api/service/api-example-microservice/1.0

REQUIRES

WebService::HMRC

EXPORTS

Nothing

PROPERTIES

Inherits from WebService::HMRC::Request.

METHODS

Inherits from WebService::HMRC::Request.

hello_world()

Retrieve a "Hello World" message. Does not require authorisation.

Returns a WebService::HMRC::Response object.

hello_application()

Retrieve a "Hello Application" message. This is an application-restricted endpoint which requires that this module's server_token property be set.

Returns a WebService::HMRC::Response object.

hello_user()

Retrieve a "Hello User" message. This is a user-restricted endpoint requiring permission for the hello service scope.

Returns a WebService::HMRC::Response object.

INSTALLATION

To install this module, run the following commands:

perl Makefile.PL
make
make test
make install

AUTHORISATION

Except for a small number of open endpoints, access to the HMRC APIs requires appliction or user credentials. These must be obtained from HMRC. Application credentials (and documentation) may be obtained from their Developer Hub

Access to the HMRC Hello World service requires that an application be registered with HMRC and 'subscribed' for this api.

This module allows all three of the possible authorisation types to be exercised.

The hello_world() method accesses an 'open' endpoint and does not require authorisation.

The hello_application() method accesses an 'application-restricted' endpoint and therefore requires a server token for authorisation. This is issued when the application is registered with HMRC and may be retrieved from the HMRC Developer Hub.

The hello_user() method accesses a 'user-restricted' endpoint and therefore requires an access token for authorisation, obtained when a user grants permission to the application for the hello service scope.

For more details on obtaining and using access tokens, See WebService::HMRC::Authenticate.

Further information, application credentials and documentation may be obtained from the HMRC Developer Hub.

TESTING

The basic tests are run as part of the installation instructions shown above and do not require authorisation with HMRC. A call will be made to the open /hello/world api endpoint, which requires a working internet connection and that the HMRC sandbox test environment is operational.

Developer pre-release tests may be run with the following command:

prove -l xt/

With a working internet connection and appropriate HMRC credentials, specified as environment variables, interaction with the protected HelloWorld endpoints can be tested:

• Test access to an application-restricted endpoint:

  HMRC_SERVER_TOKEN=[MY-SERVER-TOKEN] make test TEST_VERBOSE=1

• Test access to a user-restricted endpoint:

  HMRC_ACCESS_TOKEN=[MY-SERVER-TOKEN] make test TEST_VERBOSE=1
