# FAQ This page answers common questions about VirtualCar360, Player, Player 360, video, certificates and API integration. ## General ### What is VirtualCar360? VirtualCar360 is a solution for presenting vehicles online using photos, 360° galleries, interactive Players, hotspots, video materials, certificates and API integrations. ### What is the difference between the Player and the API? The Player is a ready-made component embedded as an `iframe`. The API is used to retrieve data such as galleries, photos, hotspots and video links for custom implementations. ### When should I use the Player? Use the Player when you want to quickly embed a complete vehicle presentation without building a custom gallery. ### When should I use Player 360? Use Player 360 when you want to present a smooth interactive 360° rotation of a vehicle. ### When should I use the API? Use the API when you want to build your own gallery, import data into another system, archive photos or integrate with CRM, DMS or a classified portal. ## Access and authorization ### How do I get an API key? Contact VirtualCar360 support. The key can be assigned to one location or multiple locations as a group key. ### Is the API key required? Yes. API calls require the `key` query parameter. Player URLs also require a key when they retrieve data from VirtualCar360. ### Can one key work for multiple locations? Yes. A group key can be configured by support for multi-location or multi-brand organizations. ## Player ### How do I embed the Player? ```html ``` ### Does the Player require a backend? No. For simple embedding, the Player can be used directly as an iframe. ### Can the Player load by VIN? Yes. Use the `vin` parameter. ### Can the Player load by registration number? Yes. Use the `numberplates` parameter. ### Can the Player load by `carId`? Yes. `carId` points to a specific Player presentation. ### Does the Player support hotspots? Yes, if hotspots are available for the gallery. ### Can the Player show certificates? Yes, if a certificate is available and configured for the vehicle. ## Player 360 ### What is Player 360? Player 360 is a Player variant for smooth interactive vehicle rotation. ### How many frames does Player 360 use? Depending on configuration, Player 360 can use 180 or 360 frames. ### Are all frames real photos? No. Intermediate frames can be generated by AI from 4 or 8 original vehicle shots. ### Do AI-generated frames have hotspots? No. Hotspots can be available only on original photos. ### How does zoom work? When zooming, the Player moves to the nearest original photo and zooms into that source image. ## Video ### Is video available by default? Not always. Contact support to enable video generation. ### What does the default video show? It shows a 360° vehicle rotation, usually around 20 seconds long, generated from 4 or 8 photos. ### Where is video stored? In VirtualCar360 and on Vimeo. On request, it can also be uploaded to the customer's YouTube channel. ## Certificate ### Can certificates be retrieved by VIN? Yes. The Certificate API retrieves certificates by VIN. ### What does the Certificate API return? It returns URLs for `widget`, `onepage` and available `pdf` files. ### Can I embed a certificate in iframe? Yes. Use the `widget` URL for embedding. ## Troubleshooting ### The Player does not show a gallery. What should I check? Check the API key, vehicle identifier, location access and whether the vehicle has a gallery. ### The API returns `404`. What does it mean? Usually no data was found for the provided VIN, registration number or `carId`. ### Video is missing. Why? Video may not be enabled, may not have been generated yet or YouTube integration may not be configured. ### Certificate PDF link does not work. Why? The PDF URL may be temporary. Fetch a fresh certificate response from the API.
