# Download campaign source

> Create a temporary download URL for a campaign CSV source.

Requires a Labs `super_user` OAuth bearer token. The campaign must belong to the selected workspace and use a CSV source. Other source types return `400`; a missing campaign returns `404`. The returned URL expires in 900 seconds. Treat the contact file and URL as sensitive.
