Security & Reliability
The ClickSend SMS integration enables seamless SMS messaging capabilities through a robust API interface, allowing you to programmatically send SMS messages, manage contact lists, and handle messaging workflows within your applications. This integration uses secure OAuth authentication, ensuring only authorized workflows access your SMS messaging functionalities.
Key benefits include simplified SMS messaging implementation, flexible sender ID management, and contact list integration capabilities. Relevance AI handles API operations (like sending messages) in the background—so you don’t have to worry about errors, formatting, or limits.
Built-in validation and type conversion ensure your workflows run smoothly, even when data formats vary, such as ensuring phone numbers are in E.164 format.
No training on your data
Your data remains private and is never utilized for model training purposes.
Security first
We never store anything we don’t need to. The inputs or outputs of your tools are never stored.

To get the most out of the ClickSend + Relevance AI integration without writing code:
- Start with a clean contact list: Ensure your contacts are formatted in E.164 format for seamless SMS delivery.
- Use templates: Relevance AI provides pre-built workflows for sending SMS messages—ideal for quick implementation.
- Connect carefully: Verify your ClickSend account and OAuth credentials during setup to avoid authentication issues.
- Test before scaling: Send test messages to a small group to ensure everything works as expected before launching to a larger audience.
- Watch for rate limits: Implement rate limiting strategies, such as exponential backoff, to manage API request limits effectively.
