What you’ll need
You don't need to be a developer to set up this integration. Follow this simple guide to get started:
- A Relevance AI account
- An Airtable account with access to the base and table you'd like to use
- Authorization (you'll connect securely using OAuth—no sensitive info stored manually)
Security & Reliability
The Textline integration with Relevance AI utilizes secure OAuth authentication, ensuring that only authorized workflows can manage your SMS communications and contact data. Relevance AI handles API operations (like sending messages, creating contacts, and sending mass announcements) seamlessly in the background—so you don’t have to worry about errors, formatting, or rate limits.
Built-in validation and error handling ensure your workflows run smoothly, even when dealing with various phone number formats or potential delivery issues.
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 Textline + Relevance AI integration without writing code:
- Start with a clean contact list: Ensure all phone numbers are valid and formatted correctly to avoid delivery issues.
- Use templates: Relevance AI provides pre-built workflows for sending messages, creating contacts, and mass announcements—perfect for quick setup.
- Connect carefully: Verify that you have the correct OAuth credentials and permissions set up during integration.
- Test before scaling: Send messages to a small group or test contacts first to ensure everything works as expected.
- Monitor API usage: Keep an eye on rate limits and implement exponential backoff strategies to handle potential throttling.
