Player External API

The Player External JavaScript IFrame API provides third-party developers the ability to deeply integrate Seenic Tours to their solutions.

Using this API provides ability to make custom filtering, use your own website components to control Seenic Tours and make it look like part of your website/application.

What you can do

Send method calls from the parent window to the iframe
Subscribe to state and receive responses from the iframe
Use a simple, promise-based API from your application code

How it works

The library establishes a messaging channel between the parent page and the iframe. All communication uses the standard browser postMessage API.

Getting Started

Include the script

Add the API script to your page next to the iframe. Prefer loading it after the iframe so the target is available.

<iframe
  id="seenic-player"
  src="https://tour.seenic.io?locationId=5772"
></iframe>
<!-- Production (minified) -->
<script src="https://cdn.seenic.io/player-external-api.min.js"></script>
<!-- Or non-minified (debug) -->
<!-- <script src="https://cdn.seenic.io/player-external-api.js"></script> -->

Or load it as an ES module:

<iframe
  id="seenic-player"
  src="https://tour.seenic.io?locationId=5772"
></iframe>
<script
  type="module"
  src="https://cdn.seenic.io/player-external-api.js"
></script>

Download the script

Prefer to self-host? Download the embeddable script and serve it from your own domain:

player-external-api.min.js — minified, for production
player-external-api.js — non-minified, for debugging

You can also grab both files interactively from the Sandbox page.

Get the API instance

Obtain the client by passing the iframe element (or its selector):

const iframe = document.getElementById("seenic-player");
const api = PlayerExternalAPI(iframe);

// Or with a selector
const api = PlayerExternalAPI("#seenic-player");

Optionally enable strict origin validation (recommended only if your player origin is fixed):

const api = PlayerExternalAPI("#seenic-player", {
  targetOrigin: "https://tour.seenic.io",
});

Wait for the player

The player may take a moment to initialize after the iframe loads. Subscribe to on_ready before calling methods:

api.subscribe("on_ready", () => {
  console.log("Player is ready");
  // Safe to call api.send(), etc.
});

Call a method

Methods are sent to the iframe with a type and optional payload:

// With a response
const result = await api.send("set_point", { pointId: 123 });
console.log(result);

Listen for changes emitted from the iframe:

api.subscribe("subscribe_to_app_state", (data) => {
  console.log("State received:", data);
});

// Unsubscribe when done
const unsubscribe = api.subscribe("subscribe_to_app_state", handler);
unsubscribe();

API Overview

The Player External API object is created by calling PlayerExternalAPI(iframe, options?) with the target iframe element or a CSS selector string. Options may include targetOrigin, timeoutMs, and debug.

Client methods

Method	Description
`send(type, payload?)`	Sends a method call to the iframe. Returns a Promise that resolves with the response payload.
`subscribe(type, callback)`	Subscribes to an event from the iframe. Returns an unsubscribe function.
`destroy()`	Tears down listeners, rejects pending requests, and unsubscribes from all events.

Wire format

Outbound requests use kind: "PlayerExternalAPI:request" with { id, type, payload }. Subscriptions use kind: "PlayerExternalAPI:subscribe" / "PlayerExternalAPI:unsubscribe".

Inbound responses and events include a type string and optional payload. Failed requests reject with a PlayerExternalAPIError that may include data, responsePayload, and responseType from the player.

Naming

api.send() and api.subscribe() types use snake_case (for example get_tour_data, on_marker_click, subscribe_to_app_state).

});

await api.send("set_filtered_units", {
  units: [{ id: "Q1B1F1U0001" }],
});
await api.send("set_point", { pointId: 3 });

// Listen for events
api.subscribe("on_ready", () => console.log("Player is ready"));
api.subscribe("on_marker_click", (payload) =>
  console.log("Marker clicked:", payload),
);
api.subscribe("subscribe_to_app_state", (data) =>
  console.log("App state:", data),
);

Methods

Use the Sandbox page to run the player in an iframe and try send and subscriptions against the bundled player-external-api.js.

Methods are sent via api.send(type, payload) and return a Promise when the iframe responds. Use await api.send(...) to wait until the method has completed.
Events are subscribed via api.subscribe(type, callback), which returns an unsubscribe function.

Method and event type strings use snake_case (for example get_tour_data, on_marker_click).

Data & lists

get_markers_list

Returns all markers currently in the player as a JSON array.

Example:

const response = await api.send("get_markers_list");
console.log("Markers in player:", response.payload.markers);

Example response:

api.send() resolves with the full response envelope; the data is under payload.

    ]
  }
}

Events from iframe

Subscribe with api.subscribe(type, callback). The returned function unsubscribes.

on_ready

Fired once when the external API plugin inside the player has finished initializing. Subscribe as early as possible so you do not miss the event if the plugin is already ready when you attach.

Example:

api.subscribe("on_ready", (event) => {
  console.log("Player is ready", event.payload);
});

Example event:

The subscription callback receives the full response envelope; read the data from payload.

{
  "kind": "PlayerExternalAPI:response",
  "type": "on_ready",
  "status": "success",
  "payload": { "ready": true }
}

on_marker_click

Fired when the user clicks a marker in the player.

Payload: { markerId, text?, locationId, type?, unitId?, actionType?, actionPayload } (fields may vary by marker type)

Example:

api.subscribe("on_marker_click", (event) => {
  const marker = event.payload;
  console.log("Marker clicked:", marker.markerId, marker.unitId);
});

Example event:

{
  "kind": "PlayerExternalAPI:response",
  "type": "on_marker_click",
  "status": "success",
  "payload": {
    "markerId": "Q1B5S1F1U5111",
    "text": "Unit 5111",
    "locationId": 5772,
    "type": "Unit Preview",
    "unitId": "Q1B5S1F1U5111",
    "actionType": "Go To Location and Point",
    "actionPayload": {
      "hotspotId": null,
      "actionLocationId": null,
      "actionPointId": 3,
      "actionCycleId": null,
      "actionViewId": null,
      "actionEventData": null
    }
  }
}

subscribe_to_app_state

Streams app state updates on every heartbeat from the player. Uses camelCase for the subscription type name.

Example:

const unsubscribe = api.subscribe("subscribe_to_app_state", (event) => {
  console.log("App state update:", event.payload);
});
// Call unsubscribe() when you no longer need updates

Example event:

Each heartbeat pushes the same app-state shape returned by get_app_state, under payload.

{
  "kind": "PlayerExternalAPI:response",
  "type": "subscribe_to_app_state",
  "status": "success",
  "payload": {
    "locationId": 5772,
    "navigationMode": "points",
    "viewMode": "panorama",
    "floor": 1,
    "current": { "pointId": 3, "cycleId": null, "cycleViewId": null },
    "visibleMarkers": ["Q1B5S1F1U5111"],
    "motion": {
      "active": true,
      "targetType": "point",
      "targetPointId": 5,
      "targetCycleId": null,
      "targetCycleViewId": null,
      "targetLocationId": null,
      "progress": 0.42
    },

Filtering

set_filtered_units

  units: [{ id: "Q1B5S1F1U5111" }, { id: "Q1B1S1F2U1205" }],
});
console.log("Units hidden:", response.payload.filteredOutCount);

Example response:

{
  "kind": "PlayerExternalAPI:response",
  "type": "set_filtered_units",
  "status": "success",
  "id": "1717000000000:4",

if (firstMarkerId) {
  const response = await api.send("locate_marker", { markerId: firstMarkerId });
  console.log("Located at point:", response.payload.pointId);
}

Example response:

cycleId and viewId are only present when the location uses cycles navigation.

set_point

Moves the camera/view to a tour point (ID from get_tour_data). Optionally sets camera orientation in degrees when navigating to the point.

Payload: { pointId: number, pitch?: number, yaw?: number }

pitch and yaw are optional; when either is provided, both must be sent together.
pitch is in [-90, 90]; yaw is in [0, 360).

Example:

await api.send("set_point", { pointId: 3 });

// With camera angles
const response = await api.send("set_point", { pointId: 3, pitch: 0, yaw: 90 });
console.log(response.payload);

  "kind": "PlayerExternalAPI:response",
  "type": "set_point",
  "status": "success",
  "id": "1717000000000:6",

  "kind": "PlayerExternalAPI:response",
  "type": "set_cycle_view",
  "status": "success",
  "id": "1717000000000:7",
