App Integration

Build apps that integrate with external services via Membrane. Uses the Membrane CLI.

Use this skill when you need to add third-party integrations to a product — connecting customers to external apps, running actions on their behalf, syncing data, or providing AI agent tools.

How Membrane Works

Membrane is an integration engine. You define what your app needs (which external apps, what operations, what data) and Membrane handles authentication, API calls, and data transformation.

Core Concepts

Workspace — your project in Membrane. Contains all integrations, connectors, and configuration for your product.

Customer — a user or organization in your product. Each customer gets their own set of connections and integration state. Identified by a unique ID you choose (e.g. your user/org ID).

Connector — a pre-built adapter for an external app (e.g. Slack, HubSpot). Handles authentication (OAuth, API keys), API client setup, and connection testing. Membrane has connectors for thousands of apps — if one doesn't exist, Membrane Agent can build it.

Integration — the relationship between your product and an external app. Defined in your workspace, it groups connectors, actions, data collections, and flows for a specific app.
