Twilio SMS Notification

Class: TwilioSMSNotificationBlockV1

Source: inference.core.workflows.core_steps.sinks.twilio.sms.v1.TwilioSMSNotificationBlockV1

The 📲 Twilio SMS Notification ✉️ block enables sending text message notifications via the Twilio SMS service, with flexible features such as dynamic content, message truncation, and cooldown management.

The block requires Twilio setup - this article may help you configuring everything properly.

✨ Key Features

• 📢 Send SMS: Deliver SMS messages to designated recipients.

• 🔗 Dynamic Content: Craft notifications based on outputs from other Workflow steps.

• ✂️ Message Truncation: Automatically truncate messages exceeding the character limit.

• 🕒 Cooldown Control: Prevent duplicate notifications within a set time frame.

• ⚙️ Flexible Execution: Execute in the background or block Workflow execution for debugging.

Type identifier

Use the following identifier in step "type" field: roboflow_core/twilio_sms_notification@v1to add the block as as step in your workflow.
