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 Telnyx account
- A Relevance AI account with API access
- Authentication credentials from both platforms (API keys will be required)
Security & Reliability
The Telnyx integration utilizes a unified API interface to provide robust communication capabilities, including SMS, voice, fax, and phone number management. This integration allows developers to seamlessly implement enterprise-grade communication features into their applications.
With secure OAuth authentication, only authorized workflows can access your Telnyx data. The integration handles API operations (like sending messages, making calls, and sending faxes) in the background—eliminating concerns about errors, formatting, or limits.
Built-in validation ensures that phone numbers are in the correct E.164 format, and type conversion guarantees that your workflows run smoothly, even when data formats vary. Additionally, webhook-based event notifications keep your application updated with real-time events.
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 0CodeKit + Relevance AI integration without writing code:
- Start with a clear setup: Ensure your 0CodeKit account is properly configured with the necessary OAuth credentials and permissions.
- Utilize example code: Leverage the provided code snippets for PDF compression and barcode reading to jumpstart your integration.
- Validate inputs: Always check your input parameters for correctness before making API calls to avoid unnecessary errors.
- Test with sample data: Run your automations using test PDFs and images to ensure everything works smoothly before going live.
- Monitor API usage: Keep an eye on your API calls to avoid hitting rate limits, and implement caching where appropriate.
