openapi: 3.0.3 info: title: Flickr Activity Reflection API description: 'The Flickr API exposes the photo, group, people, place, tag, gallery, and photoset capabilities that power flickr.com. Almost all flickr.com functionality is reachable through a single REST-like endpoint `https://api.flickr.com/services/rest` using a `method=flickr.{namespace}.{method}` query parameter and `format=json&nojsoncallback=1` for JSON output. This OpenAPI specification models a curated set of the most widely used methods across the Flickr API''s 250+ method namespaces (activity, auth, blogs, cameras, collections, commons, contacts, favorites, galleries, groups, groupsDiscuss, interestingness, machinetags, panda, people, photos, photos.geo, photos.licenses, photos.notes, photos.transform, photos.upload, photosets, places, prefs, profile, push, reflection, stats, tags, test, urls). Authentication is API key + OAuth 1.0a (HMAC-SHA1). Commercial use of the API requires prior permission from Flickr.
