# Navigate

> Navigate the active tab to a URL with configurable wait strategy and timeout.

## Overview

The `/browser/sessions/{id}/navigate` endpoint navigates the currently active tab of a browser session to the given URL and blocks until the configured wait condition is met or the timeout elapses.

Only `http` and `https` URLs are accepted. The navigation is scoped to the active tab — use `POST /pages/{pageId}/activate` to switch active tabs first.

## Path Parameters

<ParamField path="id" type="string" required={true}>
  Browser session ID (UUID). Create via `POST /browser/sessions`.
</ParamField>

## Body

<ParamField body="url" type="string" required={true}>
  Absolute URL to navigate to. Must use the `http` or `https` scheme.
</ParamField>

<ParamField body="waitUntil" type="string" default="load">
  When to consider the navigation finished. One of `load`, `domcontentloaded`, `networkidle`.
</ParamField>

<ParamField body="timeout" type="integer" default="30000">
  Maximum time (ms) to wait for navigation. Range `0`–`120000`.
</ParamField>

<ParamField body="referer" type="string">
  Optional `Referer` header sent with this navigation request only. Does not persist to subsequent navigations.
</ParamField>

### Error Responses

| Status | Description                                                                     |
| ------ | ------------------------------------------------------------------------------- |
| `400`  | Invalid body — malformed URL, non-http(s) scheme, or unknown `waitUntil` value. |
| `401`  | Unauthorized — invalid or missing API key.                                      |
| `404`  | Session not found or not owned by the caller.                                   |
| `408`  | Navigation did not complete before `timeout` elapsed.                           |
| `503`  | The browser session is temporarily unreachable.                                 |

## Notes

* `waitUntil=load` waits for `document.readyState === "complete"`. `domcontentloaded` returns once the DOM parser finishes. `networkidle` waits for 500ms of no network activity (best-effort, capped at 10s).
* `referer` is per-request and does not persist to subsequent navigations.
