Yeah, Ive hit this - had to license the mailbox - so it has a direct login. 😞

Here is the hook by the way. Vote for its implementation if you think it's of any use. that hook sends the order details to the admin email and saves it in a txt file under "logs" folder

As you might know, whmcs has a problem with stripe: when the payment is not immediately confirmed by stripe (but requires to clic "capture" on stripe dashboard), whmcs does not record the order and the customer details and does not even send any notification to whmcs admin or to the customer. We solved with a hook that sends us an email with the order details, so that: - we know that there was a order attempt - we know that there might be a payment in stripe that requires manual "capture" - if necessary, we have all the client and order details in order to recreate the both client account and order. Here is the hook. <?php if (!defined("WHMCS")) { die("This file cannot be accessed directly"); } /** * Save all checkout data to a TXT file * AND email it to admin * Runs BEFORE order/invoice creation, and before redirect to Stripe. */ add_hook('ShoppingCartValidateCheckout', 1, function ($vars) { // --- 1. Clone and sanitise incoming data ------------------------------- $data = $vars; // Mask any possible card data (good practice even if Stripe never posts it) $sensitiveFields = [ 'ccnumber', 'cccvv', 'ccexpirymonth', 'ccexpiryyear', 'password', 'password2', ]; foreach ($sensitiveFields as $field) { if (!empty($data[$field])) { $data[$field] = '***masked***'; } } // --- 2. Attach cart contents from session (products, domains, etc.) --- $cart = isset($_SESSION['cart']) ? $_SESSION['cart'] : []; $payload = [ 'timestamp' => date('Y-m-d H:i:s'), 'ip' => $_SERVER['REMOTE_ADDR'] ?? null, 'user_agent' => $_SERVER['HTTP_USER_AGENT'] ?? null, 'checkoutFields' => $data, 'cart' => $cart, ]; // --- 3. Build a text representation (for file & email) ---------------- $entry = "==============================\n"; $entry .= "Checkout submitted: " . $payload['timestamp'] . "\n"; $entry .= "IP: " . ($payload['ip'] ?? 'N/A') . "\n"; $entry .= "User-Agent: " . ($payload['user_agent'] ?? 'N/A') . "\n\n"; $entry .= "DATA:\n" . print_r($payload, true) . "\n\n"; // --- 4. Save to TXT file ---------------------------------------------- $logDir = __DIR__ . '/../../logs'; $logFile = $logDir . '/pre_stripe_checkout.txt'; if (!is_dir($logDir)) { @mkdir($logDir, 0700, true); } @file_put_contents($logFile, $entry, FILE_APPEND); // --- 5. Send email to admin ------------------------------------------- // This uses WHMCS' built-in admin notification helper. // The "system" type means it goes to the system email / admin notifications. if (function_exists('sendAdminNotification')) { $subject = 'Pre-Stripe Checkout Captured'; // Use <pre> so the print_r formatting is readable in HTML email $message = nl2br(htmlspecialchars($entry)); sendAdminNotification('system', $subject, '<pre>' . $message . '</pre>'); } // IMPORTANT: Do NOT return an error. Just let checkout continue. return; }); I suggest to implement it. It would be great if it would offer some sort of customization in the admin area.

Please get in touch with us here https://whmcsglobalservices.com/whmcs-custom-development/ , and we can develop the custom Telegram module as we developed for WhatsApp, so Telegram is not a big deal for us.

Hey WHMCS Community So here’s the thing… I love WHMCS. It’s great. But right now, it has a little “quirk” when it comes to shared mailboxes. Imagine this: I’ve got my main mailbox doing its thing, happily bringing in emails. But then there’s the shared mailbox, the one that all the support team emails go to. WHMCS? It sees it… but then pretends it doesn’t exist. 😅 Here’s the geeky version: WHMCS currently uses /me/messages from Microsoft Graph API. This only fetches emails from the authenticated user’s mailbox. Shared mailbox? Nope, invisible. Even if Full Access is granted in Exchange and you’ve got all the delegated permissions like Mail.Read.Shared, WHMCS is like, “I don’t see anything here. Must be Monday.” The right way (according to Microsoft Graph) is: GET https://graph.microsoft.com/v1.0/users/{shared-mailbox}/mailFolders/inbox/messages Yes, WHMCS, that mailbox does exist, and yes, I do have permission to read it. What I’m asking: Can WHMCS please natively support shared mailbox imports? Guidance on exactly which delegated permissions are needed (so I don’t go on a wild goose chase for nothing). Support for the correct Graph API endpoint. Bonus points: documentation for optional PHP session settings for cross-site OAuth flows (because apparently, cookies are shy and need proper settings to stick around). Expected outcome: Fetch emails from shared mailboxes without needing a license for it. Less headache, more sanity. WHMCS behaving like the email superhero it’s meant to be. Anyone else banging their head on the “shared mailbox wall”? Let’s commiserate, share workarounds, and maybe get WHMCS to notice that shared mailboxes exist in the universe. Thanks!

Hey Bruxs In the first test today it looks working. He generated a username now, that looks good. Thank you for your time and helpfull answer!

Email Verify Pro Automates email verification with customizable blocking overlay. What it does: Sends verification email on registration Blocks unverified users with full-screen overlay Cryptographically secure 32-byte tokens Configurable expiry and rate limiting Full overlay customization (colors, fonts, animations) Admin verification status display Features: Token expiry configuration (default: 60 minutes) Resend cooldown (default: 2 minutes) Max resend attempts (default: 7 per 24 hours) Database-backed rate limiting CSRF protection on all endpoints Automatic token cleanup via daily cron Email change re-verification Compatible with WHMCS native verification Technical Details: Addon module with hook integration Uses existing WHMCS database columns (email_verified_at, email_verification_token, email_verification_token_expiry) Creates two tables: mod_email_verify_pro (settings), mod_email_verify_pro_rate_limit (tracking) No core table modifications Verification URL: index.php?m=email_verification&verify=TOKEN Languages: English, Russian, Dutch Requirements: WHMCS 8.0+, PHP 7.4+, MySQL 5.7+ Installation: Upload modules folder to WHMCS root Activate in Setup → Addon Modules Configure token expiry and rate limits Customize overlay appearance Edit email template in Setup → Email Templates → "Email Verification" Client Features: Receives verification email on registration Clicks link to verify Re-verify required on email change Resend verification email (rate limited) Admin Features: View verification status in client profile Configure token expiry Set rate limit parameters Full overlay styling control Automatic cleanup of expired tokens Why it exists: Built because WHMCS native email verification doesn't block access. Users could skip verification and access the client area. This module enforces verification with a blocking overlay and adds rate limiting to prevent abuse.

Yes, you'll need some coding work to achieve this. When you use product type "Other" with a custom Hostname field, WHMCS doesn't automatically pass that value to your provisioning module. You need a hook that maps the custom field to the domain field.

We've finally solved with a hook that catch all the necessary data when the "pay now" button is clicked. I wonder why whmcs doesn't want to implement something like that... @whmcs team.. any reason???

Most of the users who sign up for whmcs are mostly to reduce the cost of creating a complete system, that includes the payments that whmcs supports, even if the website administrator has the ability to code, we still can't see or find the problem because the stripe module is encrypted by whmcs, most of the people here have tried to contact stripe, stripe pushes it to whmcs, in the end the people who actually pay to use the services of both sides have to find a solution to the problem of both sides.

Hi there! We'd love to go over the individual requirements together and get started on this Telegram integration with you. We've just sent you an email with the info you need to get started. Looking forward to hearing from you soon!

Yes, I also thought the same. But we provisioned the server automatically after payments. If I create a custom field for the hostname, how is the server going to use that hostname? I think we’ll need some coding work to achieve this

HI You can find a couple at https://marketplace.whmcs.com/search?search=Telegram+Notification, but if you still need your ow,n then please contact me at https://www.whmcsservices.com/customworks.php

I've not tried any alternatives - this issue aside, I do like WHMCS. Instead, I implemented Stripe directly into our website and just register the payments in WHMCS using the API. It was a bit painful because Stripe offers like a million different options, but it works now and we have 0 uncaptured payments.

Can you not set as other and create a custom field for the product and label it Hostname

That's a nice idea, but this way the hostname option we offer will be gone

Yes, just use the product category Other, not VPS type.

If a client purchases a service using the credit on his account how come I cannot refund it to credit? I understand why you might not be able to refund to a credit card or PayPal since the funds did not come from that source. But I should always be able to refund to the credit balance. Now I have to add the credit manually and I cannot even mark the invoice refunded. I don't know what to do with the invoice now.

Update v 1.0.4 based on feedback from peers using this addon. Added a Monitoring system and Queue system to prevent overloading the WHMCS database during data iteration. UI and Ajax system optimization within the queue system. Added Event Type / Hook Type to the queue system. Added several event notifications. Improved error handling for compatibility with the latest WHMCS version. Optimized integration with several WhatsApp gateway providers, resolving frequent timeout issues previously experienced with one specific provider. Tested: Successfully sent 3600 messages in 1 hour to 200+ WhatsApp numbers.
