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 Flexmail account
- A Relevance AI account with access to your projects and datasets
- Authorization (you'll connect securely using API keys—no sensitive info stored manually)
Security & Reliability
The Flexmail integration with Relevance AI utilizes secure OAuth authentication, ensuring that only authorized workflows can access your email campaign management and contact operations. Relevance AI manages API operations (such as creating, updating, subscribing, and unsubscribing contacts) in the background—eliminating concerns about errors, formatting, or API limits.
With built-in validation and type conversion, your workflows will operate seamlessly, even when dealing with varying data formats. This integration streamlines contact management and subscription handling, allowing for automated processes that enhance your email marketing efforts.
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.
