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.
