Webform Yuboto

A Drupal module that provides a Webform handler to send SMS messages using the Yuboto SMS API. See more at the Yuboto Messaging Platform.

The latest Yuboto API version tested with this module is v1.10 (as of 2026-03-02).

Features

• Send SMS messages to webform submission phone numbers
• Configurable message templates with token support
• Global API key configuration through Drupal UI
• Support for custom sender names
• Comprehensive error handling and logging

Requirements

• Drupal 9, 10, or 11
• Webform module
• Yuboto SMS API account and API key

Configuration

1. Configure API Keys

Navigate to Administration > Configuration > Services > Yuboto SMS Settings (/admin/config/services/webform-yuboto):

Note: Access to this configuration page requires the "Administer Webform Yuboto SMS settings" permission, which should be granted to trusted administrators only.

Environment Control:

• The enable/disable toggle allows you to temporarily disable SMS sending without uninstalling the module, perfect for staging environments
• The debug mode toggle provides different error handling behaviors for development vs. production environments

Phone Number Validation: The module automatically validates and normalizes Greek mobile phone numbers:

• Only accepts Greek mobile numbers starting with 69
• 10-digit numbers (6912345678) are automatically prefixed with 30
• 12-digit numbers with country code (306912345678) are accepted as-is
• All normalized phone numbers use the format 3069XXXXXXXX (without + prefix)
• Invalid numbers are rejected and logged but don't interrupt form submission (unless debug mode is enabled)

2. Configure Webform Handler

1. Edit your webform
2. Go to Settings > Handlers > Add handler
3. Select Yuboto SMS from the list
4. Configure the handler settings:
   • Phone number field: Select the form field that contains the phone number
   • SMS Message: Enter the message to send (supports tokens) or leave to use the default
   • Sender Name: Enter the sender name for the SMS or leave to use the default

Token Support

You can use the following tokens in your message and sender fields:

• Webform tokens: [webform:title], [webform:id]
• Submission tokens: [webform_submission:value:field_name], [webform_submission:serial]
• Site tokens: [site:name], [site:slogan], [current-user:name]
• Global tokens: [current-date:custom:Y-m-d], etc.
