README

The SDK provides convenient access to the Currency API for applications written in the PHP Programming Language.

Requirements

PHP 7.x.x and later.

Dependencies

The library require the following extensions in order to work properly:

• Guzzle

If you use Composer, these dependencies should be handled automatically. If you install manually, you'll want to make sure that these extensions are available.

Development

Instructions for installing Composer on macOS, Linux, Unix and Windows are available here.

Install dependencies:

composer install

Installation

Install Currency API PHP SDK by running the following command:

composer require horisystems/fxdatapi

Usage Example

## create a file called currency_api.php
<?php

// Log in to the API and obtain a token (if necessary)
$loginResult = $fxdatapi->login($username, $password);
