Advertising units

Advertising units describe a sponsorship offering you sell to sponsors — the price, the format, the content rules, and the dates that are available. Each unit owns a set of advertising slots, one per date.

• title, description, behavior — what the sponsorship is and how it's displayed
• price — the cost in cents that a sponsor pays per slot
• allows_html, allows_image, max_characters — the content rules sponsors have to follow when submitting
• submission_deadline_days — how many days before a slot's date the sponsor must submit their content
• status — active or inactive (inactive units don't accept new bookings)

Creating or updating a unit's dates field automatically creates or removes the corresponding slots. Slots are where sponsor content lives and where the booking, content submission, and approval workflow happens.
