# Base URLs

> Sandbox and production endpoints for the Onboard Business API.

The Onboard Business API is served over HTTPS. Pick the base URL for the
environment you're targeting and append the endpoint path from the API
reference.

| Environment            | Base URL                             |
| ---------------------- | ------------------------------------ |
| Production             | `https://business-api.onboard.xyz`   |
| Production (alternate) | `https://api-3p.onboard.xyz`         |
| Sandbox                | `https://external.dev.onboardpay.co` |

For example, [Get API Info](/api-reference/endpoints/info/get-api-info)
(`GET /exchange/api/info`) in production is:

```http theme={null}
GET https://business-api.onboard.xyz/exchange/api/info
```

## Production

`https://business-api.onboard.xyz` is the primary production base URL — use it
for new integrations. `https://api-3p.onboard.xyz` is an interchangeable alias
that resolves to the same production gateway, so integrations already pointed at
it keep working. Pick a single host per integration and use it consistently.

## Sandbox

Build and test your integration against sandbox before going live. No real
funds move on this environment.

<Note>
  Every request is authenticated regardless of environment — the same API key
  and HMAC signature are required in sandbox and production. See
  [Authentication](/api-reference/authentication).
