Hi Syead,

Thank you for the response. The endpoint is not documented in the public API documentation. I can't speak to whether it is officially supported by Quorum, but I do know that campaign is a very important piece of the data model. I'm able to access the endpoint via URL like this: 

https://www.quorum.us/api/campaign/{id}/?username={name}&api_key={key}
