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 Sellsy account
- A Relevance AI account with access to your workspace
- Authorization (you'll connect securely using API keys—no sensitive info stored manually)
Security & Reliability
The integration leverages secure OAuth authentication to safely access your Sellsy data, with Relevance AI managing API operations like GET, POST, PUT, PATCH and DELETE behind the scenes—eliminating concerns about authorization, formatting or rate limits.
Built-in request validation and response handling ensure reliable data exchange between your workflows and Sellsy's API endpoints.
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.
