  title: 99designs Coupons API
  description: 'The 99designs API lets platforms and partners embed a fully-managed creative marketplace: search and match designers, collect design briefs, place orders against 99designs products, and generate partner coupons. Authentication uses a pair of API key headers (Api-Key-Id and Api-Key-Secret) issued by 99designs after a partner requests access.'
