Connect custom APIs to Agent

By Steven Van · 2026-09-18

Pro and Enterprise workspace admins can now link Replit Agent to outside APIs with custom connectors, currently in beta.

Pro and Enterprise teams can now connect Replit Agent to APIs outside its integration library using custom connectors, in beta. Workspace admins add a base URL, describe the API and how Agent should use it, and configure authentication, then optionally test a read-only endpoint before saving.

Custom connectors are added to the workspace rather than a personal account, and only authorized workspace admins can create or manage them. Credentials go in the authentication fields only, not in the connector description or Agent instructions, which are capped at 500 characters. Full setup details are in the original announcement.
