A collection is a container inside of a data source. A data source can have many collections, but a collection can only belong to one data source. A collection can be thought of as a tab or individual sheet in a spreadsheet file. In the case of a CSV file, there would only be a single collection. Each collection contains a schema, items, collection properties, and metadata collections.
The collection endpoints are responsible for creating, updating, and deleting collections. The individual endpoints are outlined below. Each endpoint takes optional access tokens to determine access to the requested collection. A user can only modify collections if they have access to the data source.
