# Choose your integration path

> Pick the guide that matches your organization type — merchant, PSP, or bank

Clausum onboarding sets your **`organization_type`**, which determines required API fields, dashboard navigation, and which modules apply to your contract.

<Note>
  Not sure which path you are on? Check **Dashboard → Configuración → Empresa** or ask your Clausum account team.

## How documentation is organized

| Layer                  | What it is                                                                            |
| ---------------------- | ------------------------------------------------------------------------------------- |
| **Segment guides**     | End-to-end checklist for *your* profile — what to integrate, in what order            |
| **Capability modules** | Deep dives per feature (assess, webhooks, payout, …) — linked from your segment guide |
| **Core concepts**      | Shared mechanics (auth, decisions, blocklists)                                        |
| **API reference**      | OpenAPI 1.3.0 playground                                                              |

See the full [capability catalog](/concepts/capabilities) for which modules each segment typically uses.
