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 Missive account
- A Relevance AI account with API access
- Authorization credentials (you'll connect securely using OAuth—no sensitive info stored manually)
Security & Reliability
The Missive & Relevance AI integration utilizes secure OAuth authentication, ensuring that only authorized workflows can access your Missive data. Relevance AI manages API operations (such as listing contacts, creating drafts, and posting notifications) in the background—so you don’t have to worry about errors, formatting, or limits.
Built-in validation and type conversion guarantee that your workflows operate smoothly, even when data formats differ.
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 Missive + Relevance AI integration without writing code:
- Start with a well-organized contact book: Ensure clear naming conventions and consistent data formats for contacts.
- Utilize pre-built workflows: Relevance AI provides templates for managing contacts, creating drafts, and posting notifications—perfect for quick setup.
- Authenticate carefully: Double-check your OAuth credentials and permissions to ensure proper access to Missive.
- Test your API calls: Use test data to validate your integration before deploying it in a live environment.
- Monitor API usage: Keep an eye on rate limits and implement caching strategies to optimize performance.
