Connect any system to Fin with a custom REST API data connector
Overview
Fin's REST API connector lets you integrate any internal or external system, giving Fin access to proprietary data sources with no off-the-shelf connector required.
How it works
Go to Fin AI Agent → Train → Tasks → Manage Data connectors. Select a template, use an AI recommendation, or create a custom connector.
Set up the API call to your REST API system. Configure request parameters, authentication (token-based or OAuth), and map the response fields Fin should use.
Data connectors require JWT user authentication to go live. Connectors can only be fully tested in production, not in test workspaces.
Configure
Data connectors support both read and write operations. Fin can fetch data to personalize answers and execute actions like processing refunds, updating accounts, or modifying subscriptions in connected systems.
