# Getting Started

#### Authentication

Secoda API's require an Authorization header with a Bearer token. You can generate an API key in your workspace, as outlined [here](https://docs.secoda.co/api/authentication).

#### Base URL and API Versioning

To determine the base URL of your API requests, please refer to the chart below.

| Workspace URL  | Base URL       |
| -------------- | -------------- |
| app.secoda.co  | api.secoda.co  |
| eu.secoda.co   | eapi.secoda.co |
| apac.secoda.co | aapi.secoda.co |

For teams with an On Premise or Managed instance with a custom domain, the Base URL is the custom domain followed by the appropriate API version path (e.g., `/api/v1/` or `/api/v2/`).
