README

This repository contains a PHP SDK for use with the Alpaca API.

DISCLAIMER: This is NOT an official SDK, it is not affiliated with nor endorsed by Alpaca in any way.

Release Notes

v3.0.0

With the release of v3.0.0 of this library we use the Alpaca Data API v2. The getLastTrade and getLastQuote methods are backwards compatible and require no changes to your codebase.

⚠️ The getBars method is NOT backwards compatible so you will need to update your codebase to use the new method signature found in the Market Data section below.

v2.0.0

With the release of v2.0.0 of this library we use v2 of the Alpaca API. However, the methods are all backwards compatible with v1.0.0 of this library and v1 of the Alpaca API so upgrading should be as simple as updating the package version in your composer.json file and installing. Everything should work as it did before but now you'll have access to the new methods and new method parameters.

Installation

NOTE: This package currently requires PHP >= 7.2.5

$ composer require jeffreyhyer/alpaca-trade-api-php

Usage

From within your PHP application you can access the Alpaca API with just a couple of lines:

<?php

require './vendor/autoload.php';

use Alpaca\Alpaca;

$alpaca = new Alpaca("--KEY--", "--SECRET--");

$positions = $alpaca->getPositions();

OAuth

From v2.1.0 this package supports authenticating users via OAuth to the Alpaca API. For a detailed explanation on the OAuth flow, see the Alpaca Docs.

The following methods can be used to request Authorization to access an external users Alpaca account and retrieve an access token to make API calls on their behalf.

getOauthAuthorizeUrl($client_id, $redirect_uri, $scope = "", $state = null)

Provide your applications $client_id and an authorized/whitelisted $redirect_uri as well as your desired $scope and a random $state value. This function will return the URL to which you should redirect your user to in order to Authorize your application to access their account.

getOauthAccessToken($code, $client_id, $client_secret, $redirect_uri)

Once the user has authorized your application to access their account, Alpaca will redirect the user back to your application ($redirect_uri). In the URL will be a code parameter, you will pass that as the $code parameter to this function along with your $client_id and $client_secret and your original $redirect_url. This function will return an access token that can then be used to call the Alpaca API on behalf of that user/account.

To start using the access token call setAccessToken($token) with the value of the token.

Once authenticated, you can call getOauthAccessTokenDetails() to get the details of the access token (status, validity, etc).

API

Constructor

To get started initialize the Alpaca class with your Alpaca Key and Secret. You can also set the third parameter to enable or disable paper trading. The default is true to enable calling against the paper trading endpoint.

use Alpaca\Alpaca;

$alpaca = new Alpaca("KEY", "SECRET", true);

// This call will now work as expected if your KEY and SECRET are valid.
// If not, the response will contain an error explaining what went wrong.
$resp = $alpaca->getAccount();

You can change these values after initialization if necessary using the following methods:

setKey($key)

Set your Alpaca Key

setSecret($secret)

Set your Alpaca Secret

setPaper(true)

Enable or disable paper trading. true = Paper Trading, false = Live Trading.

Response

All methods return an instance of the \Alpaca\Response class which has a number of convenient methods for working with the API response.

getCode()

Returns the HTTP status code of the request (e.g. 200, 403, etc).

getReason()

Returns the HTTP status reason of the request (e.g. OK, Forbidden, etc).

getResponse()

Returns the JSON decoded response. For example:

print_r($alpaca->getAccount()->getResponse());

/*

    [id] => null
    [status] => ACTIVE
