**Preparing the Integration for External HTTP API Access**
Integration Gateway integrations are exposed via their URL. We need to make two changes to our integration to prepare it for external calls. Start by navigating to the **Build page,** right-clicking on the integration, and selecting *Configure*.
1. Remove spaces from the integration's Path Name so it can be used in a URL.\
Change `User Management (Tutorial)` to `user_management_tutorial`
2. Enable HTTP API access by checking the *Enable API Access* box.
