# What is a Collection

Collections are the outputs - reports, visualizations, APIs - built to embed and share with your end-users. Each collection is built using a model in Verb.  

### The 3 Collection Types

#### Dashboard Collection

The dashboard collection allows for a series of tiles/charts and filters to be added and designed. When embedding a dashboard collection the dashboard can be embedded with or separate from the filters. 

#### Contextual Tile Collection

A contextual tile collection contains a single tile/chart that is embedded individually and can accept filter criteria contextually. For example, embedding a sparkline chart in a table.

#### [API Collection](/collections/api-collections.md)

An API collection defines data, aggregations and filters that are made available as a REST API with auto-generated documentation. API collection can be used to create custom visualizations or to provision key-based access to external users.
