(PHP Extension) Office365 IMAP with Client CredentialsSee more Office365 ExamplesDemonstrates how to interact with the Office365 IMAP server using OAuth2 client credentials. This example uses a new feature available starting in Chilkat v9.5.0.97, which is to provide the client ID, client secret, and tenant ID to Chilkat, and internally Chilkat will fetch OAuth2 access token via client credentials as necessary. Therefore, it is no longer necessary for the application to explicitly fetch the OAuth2 access token beforehand. Note: This requires the Azure Entra ID application to be configured for client credentials as detailed in this guide: Office365 App Setup for SMTP, POP, IMAP OAuth2 Client Credentials Note: This example requires Chilkat v9.5.0.97 or greater.
<?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"); // This example requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. // ---------------------------------------------------------------------------------------- // Important: // Your Azure Entra ID app must be explicitly setup to allow for the OAuth2 client credentials flow. // Please follow the detailed guide for how to do it here: // Office365 App Setup for SMTP, POP, IMAP OAuth2 Client Credentials // // Note: Your registered App must have the SMTP.SendAsApp permission. // ---------------------------------------------------------------------------------------- $json = new CkJsonObject(); // Use your App's actual client ID here: $json->UpdateString('client_id','2871da2c-8176-4b7f-869b-2311aa82e743'); // Use your App's actual client secret here: $json->UpdateString('client_secret','2hu9Q~r5QuryUcEkNbg1btLtnfU1VUXzhSCG6brH'); // Use this specific scope. $json->UpdateString('scope','https://outlook.office365.com/.default'); // Replace the tenant ID part of the URL with your tenant ID. $json->UpdateString('token_endpoint','https://login.microsoftonline.com/114d7ed6-71bf-4dbe-a866-748364121bf2/oauth2/v2.0/token'); $imap = new CkImap(); $imap->put_Ssl(true); $imap->put_Port(993); // Connect to the Office365 IMAP server. $success = $imap->Connect('outlook.office365.com'); if ($success != true) { print $imap->lastErrorText() .
