### Query Type

Sketchub Web API is based on HTTPS requests for general operations. Mostly `POST` method as `multipart/form-data` structure and all the response will be in `JSON` format.

### API Errors

You will receive error in form of json

```
{
  "status": "failed",
  "message": "API Key is missing, please add your API key as 'api_key' in POST method.",
  "status_code": "ERR_INVALID_PARAMETER"
}
