(PHP ActiveX) HMRC OAuth2 Access TokenDemonstrates how to get an HMRC OAuth2 access token from a desktop (installed) application or script. This example gets an HMRC MTD VAT read/write access token.
<?php // This example requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. // For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.OAuth2') $oauth2 = new COM("Chilkat.OAuth2"); // This should be the port in the localhost callback URL for your app. // Important: Make sure the callback URI in your HMRC developer app // is exactly "http://localhost:3017/". Don't forget the ending "/" char. // The callback URL would look like "http://localhost:3017/" if the port number is 3017. // IMPORTANT: Don't forget to setup your HMRC application to use the Redirect URI "http://localhost:3017/" as shown // here: Configure Redirect URI for HMRC application $oauth2->ListenPort = 3017; $oauth2->AuthorizationEndpoint = 'https://test-api.service.hmrc.gov.uk/oauth/authorize'; $oauth2->TokenEndpoint = 'https://test-api.service.hmrc.gov.uk/oauth/token'; // Replace these with actual values. $oauth2->ClientId = 'HMRC-CLIENT-ID'; $oauth2->ClientSecret = 'HMRC-CLIENT-SECRET'; // The scopes are documented in the HMRC reference documentation for each API. // This example gets a read/write access token for the HMRC MTD VAT API. $oauth2->Scope = 'read:vat write:vat'; // Begin the OAuth2 three-legged flow. This returns a URL that should be loaded in a browser. $url = $oauth2->startAuth(); if ($oauth2->LastMethodSuccess != 1) { print $oauth2->LastErrorText . "\n"; exit; } // For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Http') $http = new COM("Chilkat.Http"); // 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 GitHub 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... // Now wait for the authorization. // We'll wait for a max of 120 seconds. $numMsWaited = 0; while (($numMsWaited < 120000) and ($oauth2->AuthFlowState < 3)) { $oauth2->SleepMs(100); $numMsWaited = $numMsWaited + 100; } // If there was no response from the browser within 30 seconds, then // the AuthFlowState will be equal to 1 or 2. // 1: Waiting for Redirect. The OAuth2 background thread is waiting to receive the redirect HTTP request from the browser. // 2: Waiting for Final Response. The OAuth2 background thread is waiting for the final access token response. // In that case, cancel the background task started in the call to StartAuth. if ($oauth2->AuthFlowState < 3) { $oauth2->Cancel(); print 'No response from the browser!' . "\n"; exit; } // Check the AuthFlowState to see if authorization was granted, denied, or if some error occurred // The possible AuthFlowState values are: // 3: Completed with Success. The OAuth2 flow has completed, the background thread exited, and the successful JSON response is available in AccessTokenResponse property. // 4: Completed with Access Denied. The OAuth2 flow has completed, the background thread exited, and the error JSON is available in AccessTokenResponse property. // 5: Failed Prior to Completion. The OAuth2 flow failed to complete, the background thread exited, and the error information is available in the FailureInfo property. if ($oauth2->AuthFlowState == 5) { print 'OAuth2 failed to complete.' .
