FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

Basic Usage Examples
Creating a server instance
Server methods that return more than one object will return a collection, which can be treated like an array.
Requesting Carousel Resources
All of the requests for Carousel resources are created by instantiating a ModelRequest with the appropriate Model class name and passing that to the server's get method. Passing an array of parameters to the ModelRequest is also important so that your query is limited to the items you want to get.
For example, to get a set of bulletins in a given zone:
Saving a Resource
New or existing resources can be saved by passing them to the save method on a server instance.
Creating a Bulletin From A Template
Usually you will be creating new bulletins from existing templates. More information on Bulletins below.
Creating Content from File Uploads
You can create new Media and Bulletins by uploading a file to the Carousel Server. This is done by instantiating a FileUploadRequest with the appropriate Model class name and an array of parameters passed to the request. ZoneID is required. You will then add the files you wish to upload by chaining addFile methods and then pass the request to the server's upload method. This will return an array of models, one for each file that was added.
