(PHP Extension) ETrade OAuth1 Authorization (3-legged) Step 1

Demonstrates the first step in 3-legged OAuth1 authorization for the ETrade REST API. This example sends an HTTP request to the "request token URL" to get a request token that begins the OAuth1 process. (See https://developer.etrade.com/ctnt/dev-portal/getDetail?contentUri=V0_Documentation-AuthorizationAPI-GetRequestToken )

This example uses the sandbox request token URL. The live request token URL would be "https://etws.etrade.com/oauth/request_token".

Note: Requires Chilkat v9.5.0.64 or later.

<?php

// The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number.
// For example, if using Chilkat v9.5.0.48, then include as shown here:
include("chilkat_9_5_0.php");

//  Requires Chilkat v9.5.0.64 or later.

//  This requires the Chilkat API to have been previously unlocked.
//  See Global Unlock Sample for sample code.

//   At this point, your application should load the URL in a browser.
//   For example,
//   in C#:  System.Diagnostics.Process.Start(urlForBrowser);
//   in Java: Desktop.getDesktop().browse(new URI(urlForBrowser));
//   in VBScript: Set wsh=WScript.CreateObject("WScript.Shell")
//                wsh.Run urlForBrowser

//   Add the code to load the url in a web browser here...
//   Add the code to load the url in a web browser here...
//   Add the code to load the url in a web browser here...
// System.Diagnostics.Process.Start(urlForBrowser);

//  The ETrade account owner will login and grant access to the application.
//  A short verifier code will be displayed (as shown below), and this must be copy-and-pasted
//  into the next step to Complete the 3-legged OAuth1 Authorization

//  Note: The browser will NOT automatically direct you to the next page.
//  You should copy the verifier code, close the browser, and then paste the verifier
//  code into your application.
