SMS Webhooks: Automatically Route Incoming SMS Messages to Slack, Telegram, and any API
Businesses increasingly rely on SMS not only for customer communication but also as a trigger for automated workflows. Whether you're collecting leads, receiving customer replies, processing support requests, or monitoring critical alerts, manually checking incoming SMS messages is inefficient and difficult to scale.
With SMS Webhooks, every incoming message received on your virtual phone number can be instantly forwarded to one or multiple destinations, including Slack channels, Telegram chats, CRM systems, helpdesk platforms, and custom API endpoints.
This approach transforms SMS from a simple communication channel into a powerful automation tool that integrates seamlessly with your existing business processes.
What Are SMS Webhooks?
An SMS webhook is an HTTP callback that automatically sends information about an incoming SMS message to a specified URL in real time.
When a message arrives on your phone number, the platform immediately generates an HTTP request containing the message details and delivers it to your configured endpoint. This enables external systems to process incoming SMS messages without polling APIs or manually monitoring inboxes.
Typical data delivered through SMS webhooks includes:
SMS message content
Sender ID or originating phone number
Recipient phone number
Date and time of receipt
Message metadata
Delivery information
The webhook payload can be formatted as JSON, form data, or plain text depending on your integration requirements.
Why Businesses Use SMS Webhooks
Modern organizations often use SMS as part of larger business workflows. Incoming messages frequently contain valuable information that should be routed directly into business systems.
Common use cases include:
Lead Management
Automatically send incoming inquiries from SMS-enabled phone numbers into CRM platforms such as HubSpot, Salesforce, Zoho CRM, or Microsoft Dynamics.
Customer Support
Convert incoming SMS messages into support tickets and route them to helpdesk systems for immediate handling.
Team Notifications
Forward important customer replies directly to Slack channels or Telegram groups to ensure teams respond quickly.
Workflow Automation
Trigger automation platforms such as Zapier, Make, n8n, or custom applications whenever a new SMS is received.
Compliance and Monitoring
Archive incoming communications for auditing, reporting, and regulatory compliance purposes.
Multiple Webhooks Per Phone Number
One of the most powerful capabilities of modern SMS routing is the ability to configure multiple webhooks for a single phone number.
Instead of sending incoming messages to only one destination, businesses can simultaneously distribute the same SMS to several systems.
For example, when a customer sends an SMS:
The message is forwarded to a HubSpot CRM contact record.
A notification is posted to a Slack channel.
The message is stored in an internal database via API.
A Telegram notification is sent to the support team.
This multi-destination routing ensures that every department receives the information it needs without manual intervention.
Unlike traditional SMS integrations that support only a single callback URL, multiple webhook routing enables organizations to build sophisticated communication workflows from a single phone number.
