Phaxio is a modern REST API that enables developers to send and manage faxes programmatically. By integrating with Relevance AI, you can enhance your applications with intelligent fax capabilities that streamline communication and automate tasks.


Phaxio allows you to send and manage faxes programmatically through a modern REST API. With Relevance AI, you can leverage these capabilities to create intelligent workflows that automate faxing processes and enhance communication efficiency.
Secure Document Orchestration
Enables the agent to securely route, process, and manage sensitive fax communications while maintaining compliance standards
Automated Workflow Mastery
Equips the agent to create and execute sophisticated document processing workflows without human intervention
Smart Content Analysis
Enables the agent to extract, classify, and act upon faxed document content using advanced OCR and NLP capabilities
Relevance AI integrates seamlessly with Phaxio to enhance your workflows by adding powerful fax capabilities.
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 Phaxio account
- A Relevance AI account
- Authorization credentials from both platforms (API keys will be required)
Security & Reliability
The Phaxio integration utilizes secure OAuth authentication, ensuring that only authorized applications can send and manage faxes through the Phaxio API. Relevance AI facilitates API operations (like sending faxes, checking statuses, and making custom API calls) in the background—so you don’t have to worry about errors, formatting, or limits.
Built-in validation and type conversion ensure your fax operations run smoothly, even when dealing with various document formats and phone number standards.
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.
