Output

Similar to how we have on the item level, is there a way to export an entire collection to JSON or XML?

The most straightforward way is to use the API, and pass the collection id as a parameter:

/api/items?collection=1

Depending on the size of the collection and your settings for how many results the API returns, you might have to page through the results.

/api/items?collection=1&page=2

Thank you.I get a message back that the API is disabled: {"message":"API is disabled"} How do I turn it on?

Check the end user documentation for the API, and the developer documentation for the API.
