# Configuration overview

> All configuration layers — node, environment, integrations, and build export.

**Configuration** in Phinite spans several surfaces. Each layer applies at a different stage of **Design → Save → Build → Deploy**.

## Typical order

1. Configure nodes in Studio — see [Graph Studio](/graph-studio/overview) (nodes, variables, RAG).
2. Set **Env. variables** for DEV / UAT / PROD.
3. Connect **Integrations** (channels, triggers, predefined tools).
4. **Save** the graph, then **Build** — pin versions; optionally [export config to build](/configure/build-export).
5. **Deploy** or **Expose as A2A**.

<Note>
  **Save** persists the draft graph. **Build** freezes graph + tool versions — env variables and integration configs are resolved at runtime per environment, not baked into the graph JSON.
</Note>

## Layer details

### Node config (Graph Studio)

| Tab                  | Configures                                   |
| -------------------- | -------------------------------------------- |
| **Details / Prompt** | Agent mission, instructions, model selection |
| **Tools**            | Published tools attached to this node        |
| **RAG**              | Workspace collections for retrieval          |
| **Variables**        | Input and capture variables for the node     |
| **Decision**         | Conditional routing edges                    |

See [Graph Studio — Agent configuration](/graph-studio/interface/node-library) for drawer documentation.

### Environment variables

Store API keys, database URLs, and feature flags per environment. Tools reference env variable names — values differ between DEV, UAT, and PROD without code changes.

See [Env. variables](/configure/env-variables).

### Integrations

| Integration type     | Purpose                                                |
| -------------------- | ------------------------------------------------------ |
| **Channels**         | WhatsApp, Slack, Teams, web chat, voice, email         |
| **Triggers**         | API webhooks, cron, background tasks                   |
| **Predefined tools** | Third-party APIs authenticated once, enabled per graph |

See [Integrations](/configure/integrations) and [Integrations Hub](/integrations-hub/overview).

### Build export

When you **Build** or **Expose as A2A**, Phinite pins tool versions and optionally exports MCP connections and env bindings into the immutable artifact.

See [Build export](/configure/build-export).

<Tip>
  Configure integrations in DEV first, validate with **Test** and observability logs, then promote builds to UAT and PROD.
