# Collections

Collections are the containers for NFTs shared with you, your community, and your product.

On this page, we'll dive into the different Collection endpoints you can use to manage Collections programmatically. We'll look at how to query and create Collections.

Collections represents a group of related NFTs. A Collection is itself an NFT. For example, a Collection can be a group of NFTs where each NFT is a membership pass. 

## The Collection Model

The Collection model contains all the information about your Collection, such as their mint address, name, and image.
