What is Sendly SMS Integration?
This Openclaw Skills extension enables AI agents to interact with the Sendly SMS platform seamlessly. It supports single message delivery, batch processing for up to 10,000 recipients, and advanced scheduling capabilities within a five-day window. Whether you need to send one-time passwords, order confirmations, or promotional content, this skill provides the necessary endpoints and SDK methods to handle global SMS delivery with built-in sandbox testing.
By leveraging this skill, developers can ensure their AI agents handle communication workflows with precision, utilizing either the high-level Node.js SDK or the raw REST API. It includes built-in logic for handling message types and compliance, making it an essential tool for any agent-driven communication stack.
Sendly SMS Integration Use Cases
- Automated transactional notifications such as order shipping updates or OTP codes.
- Scheduled appointment reminders to reduce no-shows by setting triggers up to five days in advance.
- High-volume marketing campaigns with batch sending capabilities for up to 10,000 messages per request.
- Two-way conversation management for customer support interactions using the Conversations API.
- Cost-free sandbox testing of message flows using dedicated magic numbers to simulate various carrier responses.
How Sendly SMS Integration Works
- The AI agent initializes the skill using a Sendly API key (test or live) stored in the SENDLY_API_KEY environment variable.
- The agent identifies the message category, choosing between transactional for immediate alerts or marketing for promotional content to maintain regulatory compliance.
- Recipient numbers are validated against the E.164 format before the request is dispatched to the Sendly API.
- For scheduled messages, the system queues the content for the specified timestamp, while batch requests process multiple recipients simultaneously.
- The skill receives a structured JSON response containing message IDs, status, and credit usage, which is then used to update the internal application state.
Sendly SMS Integration Setup
To integrate this skill into your workflow, install the Sendly Node.js SDK and configure your authentication credentials.
npm install @sendly/node
export SENDLY_API_KEY='your_sk_live_or_test_key'
You should use sk_test keys initially to utilize magic numbers for testing without consuming credits.
Sendly SMS Integration Data Schema & Taxonomy
The skill organizes SMS data and metadata using the following structure to ensure transparency in delivery and billing:
| Field | Type | Description |
|---|---|---|
| id | String | Unique identifier for the message (e.g., msg_abc123) |
| to | String | Recipient phone number in E.164 format |
| status | String | Current delivery state (sent, delivered, failed) |
| messageType | String | Classification: transactional or marketing |
| segments | Integer | The number of SMS segments required for the text |
| creditsUsed | Integer | Total credits deducted based on destination and length |
| metadata | Object | Custom key-value pairs (up to 4KB) for internal tracking |
Sendly SMS Integration Advanced Features
- Intelligent Conversation Threading: Automatically groups sent and received messages into coherent conversation objects.
- AI-Suggested Replies: Utilizes the Conversations API to generate context-aware response suggestions for active threads.
- Marketing Quiet Hours: Built-in enforcement of quiet hours (9pm–8am) for marketing messages based on recipient local time.
- Full-Text Search: Query message history using keywords, status filters, and pagination limits.
- Sandbox Magic Numbers: Specialized test numbers that allow developers to simulate carrier rejections or routing errors without real-world impact.
