Creatives are any entity that can be promoted in a campaign. Tweets can include text, images, GIFs, videos, or cards. Cards can include images or videos.
Image, GIF, or video creatives are uploaded using either the POST media/upload — a simple upload endpoint that only supports images — or the POST media/upload (chunked) endpoints. These can be added to
- POST accounts/:account_id/tweets - To add cards to Tweets, use the card_uri parameter.
