# Using webhooks to receive inbound messages

> Using webhooks to receive inbound SMS and MMS messages with the Wavix Messaging API.

When building Wavix integrations, you might want your applications or services to receive inbound messages as soon as they reach an SMS-enabled phone number on your account. This allows your backend systems to process them accordingly.

To activate this feature, set a webhook URL as the default SMS endpoint for your SMS-enabled DID, or your Wavix account. You can do this using the Wavix GUI, the Wavix Profile API, or the Wavix DID numbers API.

Once a message is received by an SMS-enabled DID on your Wavix account, Wavix will automatically forward the message to a webhook registered to the DID, if one is specified. In cases where no webhook is registered to the DID, the platform will automatically forward the message to a webhook configured in your account.

<Info>
  If you need to allow Wavix IP addresses in your firewall settings, see [Webhook IP addresses](/messaging/webhook-ip-addresses).
