How to Set Up DLR Through Web Notification in BulkSMSOnline

DLR Through Web Notification allows your system to receive SMS delivery report updates from BulkSMSOnline through a callback URL. This is useful for businesses and developers who want to track SMS delivery status automatically instead of checking reports manually from the dashboard.

DLR stands for Delivery Report. It helps you understand the delivery status of your SMS messages after they are submitted to the mobile network. Depending on the destination country, route, and network support, DLR updates may help you track whether a message is delivered, pending, failed, rejected, expired, or still being processed.

  • Payment notifications
  • Booking confirmations
  • Delivery updates
  • Customer alerts
  • API-based SMS sending

Step 1: Log In to Your Account

First, log in to your BulkSMSOnline account using your registered username and password.

After logging in, you will be redirected to your dashboard. From there, you can manage your SMS campaigns, API settings, account settings, reports, billing details, and delivery tracking options.

Step 2: Open the Settings Page

Once you are inside your dashboard, look at the top-right corner of the screen and click your account name or username.

A dropdown menu will appear. Click Settings to open your account settings page.

Step 3: Find the DLR Through Web Notification Section

On the settings page, scroll until you find the DLR Through Web Notification section.

This section is where you can add the callback URL that will receive SMS delivery report updates from BulkSMSOnline.

Step 4: Enter Your DLR Callback URL

In the DLR URL field, enter or paste your callback URL. This should be a valid web address from your server or application where you want to receive delivery report notifications.

Example format:

https://yourdomain.com/dlr-callback

Make sure your URL is active, reachable, and configured to receive delivery report requests. If your server blocks incoming requests or the URL is incorrect, DLR notifications may not be received successfully.

Step 5: Save Your DLR Settings

After entering your DLR URL, click the Save button.

Your DLR Through Web Notification setting will now be stored in your BulkSMSOnline account. Future delivery report updates may be sent to the callback URL based on your route, destination, and delivery report availability.

Recommended DLR URL Requirements

Before saving your DLR URL, make sure it is properly prepared. A good DLR callback URL should:

  • Use a valid and working HTTPS URL where possible.
  • Be hosted on a reliable server.
  • Be accessible publicly from the internet.
  • Be able to receive incoming webhook or callback requests.
  • Respond quickly to incoming requests.
  • Log received delivery report data for troubleshooting.
  • Avoid redirect loops, expired links, or blocked firewall rules.

Important Notes About Delivery Reports

Delivery reports may depend on the destination country, mobile network, selected route, and operator support. In some cases, delivery report visibility may vary depending on the SMS route used for the campaign.

For important traffic such as OTP, login codes, payment alerts, and urgent notifications, choosing the right route is important. You can learn more about route options here:

Using DLR Web Notification With SMS API

DLR Through Web Notification is especially useful for businesses using SMS API integration. If your website, CRM, app, billing system, or backend service sends SMS automatically, DLR callbacks can help your system track delivery results programmatically.

You can use DLR notifications for:

  • Updating OTP delivery status
  • Tracking customer notification results
  • Updating CRM message logs
  • Monitoring transactional SMS
  • Recording failed or pending messages
  • Improving reporting for automated SMS workflows

Using DLR Reports With the Web SMS Platform

If you send SMS manually from the dashboard, you can also monitor delivery activity from your account reports where available. DLR web notification is mainly useful when you want delivery updates sent to your own system automatically.

Common DLR Statuses

DLR status names may vary depending on the route, destination, and network response. Common delivery report statuses may include:

  • Delivered: The message was delivered successfully where confirmation is available.
  • Pending: The message is still being processed or waiting for final status.
  • Failed: The message could not be delivered.
  • Rejected: The message was rejected by the system, route, or network.
  • Expired: The message was not delivered within the allowed delivery period.
  • Queued: The message is waiting to be processed.

If you need help understanding a specific DLR status, contact BulkSMSOnline support with the message ID, destination country, sending time, sender ID, and delivery status.

Testing Your DLR Web Notification

After saving your DLR URL, it is recommended to send a small test SMS campaign before using the setting for large-volume SMS traffic.

When testing, check the following:

  • The SMS message is submitted successfully.
  • Your callback URL receives the delivery report notification.
  • Your server logs the incoming request.
  • Your system stores the message status correctly.
  • Your application can handle repeated or delayed delivery updates.

Testing helps confirm that your DLR notification setup works correctly before you rely on it for production SMS traffic.

DLR Web Notification Best Practices

To improve reliability, follow these best practices when setting up your DLR callback URL:

  • Use HTTPS for better security.
  • Keep your callback endpoint stable and always available.
  • Log every incoming DLR request for future troubleshooting.
  • Store message IDs so you can match delivery reports with sent SMS records.
  • Do not expose sensitive credentials in your callback URL.
  • Make sure your server can handle repeated requests safely.
  • Use proper validation and security checks on your webhook endpoint.
  • Test the callback URL before sending large campaigns.

If your DLR web notification is not working, check the following:

  • Make sure the DLR URL was saved correctly in your account settings.
  • Confirm that the callback URL is active and publicly accessible.
  • Check whether your server firewall is blocking incoming requests.
