(PHP ActiveX) 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://apisb.etrade.com/docs/api/authorization/request_token.html )

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

$consumerSecret = 'ETRADE_CONSUMER_SECRET';

// Note: This example uses the sandbox request token URL.
// The live Get Request Token Request URL is:
// https://api.etrade.com/oauth/request_token
// This example will use the Sandbox Token Request URL:
$requestTokenUrl = 'https://apisb.etrade.com/oauth/request_token';

// If successful, the resp.BodyStr contains something like this:

// The next step is to form a URL to send to the authorizeUrl
// This is an HTTP GET that we load into a popup browser.

// At this point, your application should load the URL in a browser.
// For example, 
// in C#: System.Diagnostics.Process.Start(url);
// in Java: Desktop.getDesktop().browse(new URI(url));
// in VBScript: Set wsh=WScript.CreateObject("WScript.Shell")
//              wsh.Run url
// in Xojo: ShowURL(url)  (see http://docs.xojo.com/index.php/ShowURL)
// in Dataflex: Runprogram Background "c:\Program Files\Internet Explorer\iexplore.exe" sUrl        
// The Microsoft account owner would interactively accept or deny the authorization request.

// 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...

// 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.
