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 Nusii Proposals account
- A Relevance AI account with API access
- Authorization (you'll connect securely using OAuth—no sensitive info stored manually)
Security & Reliability
The integration uses secure OAuth authentication, ensuring only authorized workflows access your Nusii Proposals data. Relevance AI handles API operations (like GET, POST, PUT, DELETE) in the background—so you don't have to worry about authentication headers, request formatting, or API limits.
Built-in validation and path handling ensure your proposals and client data sync smoothly across the platform.
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.
